Abstract:
Abstract Abstract 1040 Background: Iron(III) polymaltose complex (IPC) shows similar efficacy to ferrous sulfate for the treatment of iron deficiency anemia but with superior tolerability. The stable structure of IPC prevents unregulated uptake of iron from the gut, avoiding an increase in non-transferrin bound iron with associated oxidative stress. IPC similars have been developed which vary in structure from the originator IPC preparation (Maltofer®, IPCM). A direct comparison between the originator and IPC similars in their potential to induce oxidative stress has not been performed. In this study, we compared acute and early toxicity in the gastrointestinal (GI) tract and liver in healthy rats randomized to IPCM, an IPC similar (Vitalix, IPCV) or a control arm. Methods: LD50 values were determined by administering single increasing doses of IPCM or IPCV (each n=12) and counting deaths at 24 hours. Three groups of rats (each n=12) then received doses equivalent to 10% of LD50 for IPCM (280 mg iron/kg/day) or IPCV (280 mg iron/kg/day), or tap water (controls) for 28 days. Iron-induced lesions in the GI tract were scored: 1, superficial 1–5 hemorrhagic points; 2, superficial 6–10, hemorrhagic points; 3, sub-mucosal hemorrhagic lesions with small erosions; 4, severe hemorrhagic lesions and some invasive lesions. Iron deposits (Prussian blue) and tissue ferritin in the liver and small intestine were assessed by immunohistochemistry. Ferritin immunostaining in the small intestine was scored: 1, none; 2, mild; 3, moderate; 4, very intense. Results: LD50 was the same for IPCM and IPCV (>2800 mg iron/kg). Animals treated with IPCV had lower food consumption and body weight vs those treated with IPCM and controls. IPCV was associated with increased serum iron and transferrin saturation vs the IPCM group, suggesting bypass of the regulated iron uptake system. Microscopically, the villi/crypt ratio and the number of Goblet cells per villi in the small intestine were significantly lower with IPCV vs IPCM or controls, and the number of eosinophils per villi was increased in IPCV-treated animals. Gross anatomy and microscopy findings showed that IPCV- treated animals experienced variable degrees of inflammation in the GI tract while the IPCM and control groups showed no lesions. Ferritin immunostaining of liver tissue indicated that iron was appropriately stored in IPCM-treated within Kupffer's cells (Prussian blue). Ferritin deposits in the small intestine were also higher with IPCM. Differences were statistically inferior for IPCV versus IPCM for clinical and iron parameters, gross anatomy, microscopic findings and ferritin immunostaining (Table). Conclusions: IPCV showed the same LD50 as IPCM, but considerably greater early GI tract toxicity. Increased numbers of eosinophils in the IPCV group suggest an allergic component of the small intestine injury in these groups. Markers of iron transport and distribution indicated less well controlled uptake and storage following ingestion of IPCV compared to IPCM. The increased levels of ferritin deposits in the small intestine of IPCM-treated animals suggests that excess iron is stored in the gut wall instead of saturating the iron transport mechanism and increasing non-transferrin bound iron levels.

Abstract:
In this paper, gradual and symmetrical long-term potentiation (LTP) and long-term depression (LTD) were achieved by applying the optimal electrical pulse condition of the interfacial phase-change memory (iPCM) based on a superlattice (SL) structure fabricated by stacking GeTe/Sb2Te3 alternately to implement an artificial synapse in neuromorphic computing. Furthermore, conventional phase-change random access memory (PCRAM) based on a Ge–Sb–Te (GST) alloy with an identical bottom electrode contact size was fabricated to compare the electrical characteristics. The results showed a reduction in the reset energy consumption of the GeTe/Sb2Te3 (GT/ST) iPCM by more than 69% of the GST alloy for each bottom electrode contact size. Additionally, the GT/ST iPCM achieved gradual conductance tuning and 90.6% symmetry between LTP and LTD with a relatively unsophisticated pulse scheme. Based on the above results, GT/ST iPCM is anticipated to be exploitable as a synaptic device used for brain-inspired computing and to be utilized for next-generation non-volatile memory.

Abstract:
Various dielectric continuum models in Gaussian 03, based on the SCRF approach, PCM, CPCM, DPCM, IEFPCM, IPCM, and SCIPCM, have been tested on a set of 54 highly polar, generally polyfunctional compounds for which experimental solvation energies are available. These compounds span a range of 13 kcal/mol in ΔGt. The root-mean-square (RMS) errors for the full set of compounds range from 2.48 for DPCM to 1.77 for IPCM. For each method, classes of compounds which were not handled well could be identified. If these classes of compounds were omitted, the performance improved, and ranged from 1.58 (PCM, 39 compounds) to 1.02 (IPCM, 42 compounds). Models in the PCM family (PCM, CPCM, DPCM, and IEFPCM) with the recommended UAHF or UAKS sets of radii rely on a highly parameterized definition of the solvent cavity. Where this parameterization was inadequate, the calculated solvation energies were less reliable. This has been demonstrated by devising a new parameterization for PCM and halogen compounds, which markedly improves performance for polyhalogen compounds. The effective radius for the portion of the cavity centered on a halogen atom was assumed to be linear in the electron-withdrawing or -donating properties of the rest of the molecule as measured by Hammett σ (for halogens on aromatic rings) or Taft σ* (for halogens on aliphatic carbons). This new parameterization for PCM was tested on a set of 45 aliphatic and 22 aromatic polyhalogen compounds and shown to do well. IPCM, which was already the best of the methods in Gaussian, can be considerably improved by a parameterization to allow for cavitation, dispersion, and hydrogen bonding. A large set of compounds was used for the parameterization to have multiple examples for each parameter and as far as possible to have molecules with multiple instances of each structural feature. In the end, 15 parameters were found to be defined by the data for 241 compounds. With this parameter set, the RMS error for the set used for fitting was 0.81 kcal/mol, and the RMS error for the original set of 54 compounds was 0.85. With this new parameterization, IPCM is clearly the best of the methods available in Gaussian 03.

Abstract:
The inter-cluster separation (ICS) algorithm adds the separation item into the objective function to minimize the fuzzy Euclidean distance and maximize the inter-cluster separation. However, ICS is sensitive to noisy data, so an improved inter-cluster separation (IICS) algorithm is proposed to deal with this problem. It is claimed that IICS is an incorporation of ICS and improved possibilistic c-means (IPCM) clustering. IICS can produce both possibilities and memberships simultaneously, and it overcomes the noise sensitivity problem of ICS and the coincident clusters problem of possibilistic c-means (PCM) clustering. Further, IICS does not depend on the parameters that exist in IPCM. The experimental results show that IICS compares favorably with ICS.

Abstract:
AbstractGeTe/Sb2Te3 superlattices, also known as interfacial phase-change memory (iPCM), exhibit significantly faster switching and are characterized by much lower power consumption and longer data retention compared to devices based on alloyed materials. In early work, the superior performance of iPCM was linked to a crystal-crystal transition between the SET and RESET states. As the primary mechanism, a change in the stacking order of Ge and Te planes within a GeTe block was suggested. Subsequent STEM studies on epitaxial GeTe/Sb2Te3 superlattices demonstrated that the GeTe blocks were not located between Sb2Te3 quintuple layers but, were incorporated inside the latter, providing a serious challenge to the early explanation. In this work, we demonstrate that changes associated with the reconstruction of the SbTe terminating layers nearest to van der Waals gap leads to a pronounced change in the density of states and can serve as an alternative explanation for a large property contrast between the SET and RESET states in GeTe/Sb2Te3 superlattices.

Abstract:
Growth of Listeria monocytogenes strains V7, Scott A, and California (initial inoculum 103/ml) at 21 or 30°C in the presence of Streptococcus Iactis (initial inoculum 0.25 or 1.0%) was determined using a medium with internal pH control (IPCM-1). The pH of the uninoculated medium (control) was 7.0 before and after incubation. Populations of L. monocytogenes in IPCM-1 without S. lactis after 30 h at 21°C were ca. 107/ml for strains V7 and Scott A and ca. 106/ml for strain California, and at 30°C they were ca. 108/ml for all three strains. When data were plotted, areas of graphs between curves representing controls and treatments were calculated to quantitate the extent of inhibition of L. monocytogenes caused by S. lactis. Each such area is called the “area of inhibition” (AI). Growth of the pathogen was inhibited by S. lactis; the degree was dependent on temperature and concentration of lactic culture and, in some instances, strain of Listeria. Greatest inhibition of each strain occurred with the largest inoculum of S. lactis and at the highest temperature. No significant difference (p>0.05) in AI or pH among the three strains was observed at 21°C. At 30°C, strain California was inhibited significantly more (p<0.05) than V7 or Scott A by both concentrations of S. lactis at 24 and 30 h of incubation. No significant difference (p>0.05) in pH was found at this temperature regardless of concentration of S. lactis or strain of Listeria. IPCM-1 inoculated with a lactic starter culture is ready for use at pH 5.5 after 15–18 h of incubation. Inhibition of Listeria was not complete at this pH under any of the experimental conditions. Substantial numbers of L. monocytogenes (103–105 CFU/ml) were present when this medium was ready for use to produce cultured dairy foods.

Abstract:
An agitated medium with internal pH control (IPCM-2) was inoculated to contain Listeria monocytogenes (strain V7, Scott A or California) at ca. 103 CFU/ml and Streptococcus cremoris (Lactococcus lactis subsp. cremoris) or Streptococcus lactis (Lactococcus lactis subsp. lactis) at 0.25 or 1.0% The inoculated medium was incubated with shaking in a waterbath at 30°C for 30 h. L. monocytogenes and lactic acid bacteria were enumerated and pH was determined at appropriate intervals. The area on a figure between curves for the control and treatment and designated as the area of inhibition (AI) was calculated and used to quantify inhibition of each strain of L. monocytogenes for a particular set of conditions in IPCM-2. Statistical analysis of AI values calculated from data obtained at 6, 24, and 30 h of incubation revealed no significant (p < 0.05) difference in inhibition among the three strains of L. monocytogenes for each type of lactic streptococcus present. Streptococcus cremoris was significantly (0.01 < p < 0.05) more inhibitory to all three strains of L. monocytogenes than was S. lactis at 24 and 30 h of incubation. IPCM-2 is considered ready for use at a pH of 5.4 or less, which was reached between 12 and 15 h of incubation in samples containing 0.25 or 1.0% S. cremoris. Populations of L. monocytogenes in such samples were ca. 104 to 106 CFU/ml regardless of strain of Listeria or percentage of S. cremoris added as inoculum. In samples initially containing 0.25 or 1.0% S. lactis, pH 5.4 was not reached until after 18–24 h of incubation. At this point all three strains of L. monocytogenes had grown to ca. 105 CFU/ml regardless of percentage of S. lactis added as inoculum. Despite the inhibition seen, substantial numbers of the pathogen were present when the medium was ready for use.

The execution of experimental Flight Test Campaign (FTC) provides all information required for the aircraft development, operation and certification. Typically the execution of a FTC encompasses three major systems as follows: Flight Test Instrumentation System (FTI) that is basically a measurement system; Real-Time Telemetry Link (RTL); and Ground Telemetry System (GTS). At the early days, for the development of small aircrafts (i.e. Fighter), the primary source for FTI data was provided by the RTL due to inherent limitations of the open reel airborne data recorders (i.e. media and size), operating under high-dynamics condition. Nowadays with the introduction of solid-state data recording devices, data integrity and reliability is no longer an issue. At the ITC 2010 Blue Ribbon Panel, Mr. Thomas Beard, the executive Director of the Air Force Flight Test Center in Edwards Air Force Base emphasized the need to reduce refly and to improve FTC efficiency. Such statement imposes a new paradigm in Telemetry, which is to improve RTL integrity and reliability level equivalent to the solid-state data recording devices. Therefore the Telemetry community will be able to execute test point validation for refly reduction and quasi realtime data reduction analysis for efficiency improvement. The major solutions that address such issue are Spatial Diversity (SD) architectures and the iNet. The SD solution requires multiple antenna system (which is very expensive) that could still produce ineffective results at high-dynamics test points (e.g. Spin). At the beginning the iNet consortium proposed the usage of TCP protocol for data transmission. Problems associated with TCP limitations such as data latency and overhead lead to the usage of UDP protocol that does not guarantee the packet delivery. To properly address these issues the IPEV R&D group proposes the iPCM Telemetry architecture to be used as RTL. The iPCM uses hybrid architecture for data transmission taking the advantage of legacy digital transmitters combined with iNet-based transceivers to retrieve missing data. The development and the evaluation of iPCM architecture will be executed as a PhD Thesis in ITA University. The expected performance and benefits of iPCM are presented and discussed.

The aeronautical industries have been suffering financial cutbacks and the market has to face new challenges associated with new companies. Telemetry community has been facing the increase of the electromagnetic spectrum usage for a variety of applications (e.g. 4G), after all telemetry is everywhere. In view of these issues and focused on the inherent requirements of the Flight Test application, the IPEV R&D group proposes the iPCM Telemetry architecture as solution for the existing reliability and bandwidth issues associated with the telemetry link. In this article, as a proof-of-concept of the iPCM architecture, it has been performed an experimental assembly. The results demonstrate the iPCM's ability to regenerate corrupted data providing the required data integrity and reliability, besides the capability to dynamically select the FTI transmitted parameter list to optimize the bandwidth link.

Abstract:
Afin de faire face à la demande croissante de mémoires de plus en plus performantes dans les systèmes informatiques, de nouvelles technologies se sont développées. Parmi elles, les mémoires résistives à changement de phase (ou PCM pour Phase-Change Memory) ont des propriétés et une maturité suffisante pour développer les nouvelles mémoires SCM (pour Storage Class Memory) comme en témoigne la récente commercialisation des produits Optane par la firme INTEL®. Néanmoins, la consommation énergétique des PCM lors de leur programmation reste élevée, ce qui limite leurs performances. L’intégration de super-réseaux (GeTe)2/(Sb2Te3)m dans des mémoires dites iPCM (pour interfacial Phase-Change Memory) est une des voies les plus prometteuse pour permettre une diminution significative des courants de programmation. Cependant, le mécanisme de transition des iPCM et la structure du matériau dans ses deux états de résistances sont encore méconnus. Dans ce contexte, l’objectif de cette thèse est d’élaborer des super-réseaux (GeTe)2/(Sb2Te3)m (m=1,2,4 et 8) cristallins, de déterminer leur structure puis de les intégrer dans des dispositifs mémoires. La pulvérisation cathodique alternée des matériaux GeTe et Sb2Te3 dans un équipement industriel de dépôt est utilisée pour effectuer l’épitaxie van der Waals de ces super-réseaux. Une optimisation du procédé par l’ajout d’une cible de Te en co-pulvérisation avec la cible de Sb2Te3 montre l’obtention de super-réseaux stœchiométriques présentant la périodicité souhaitée, ainsi qu’une orientation des plans cristallins (0 0 l) parallèle à la surface du substrat. Une description de l’ordre atomique local des super-réseaux ainsi optimisés est ensuite menée par l’étude d’images HAADF-STEM couplée à des simulations. Celle-ci révèle un phénomène d’inter-diffusion entre les couches de GeTe et de Sb2Te3 déposées aboutissant à la formation locale de GexSbyTez rhomboédriques, des mesures quantitatives de l’occupation des plans atomiques en Ge/Sb confirment aussi le phénomène. De plus, un modèle de structure à longue distance de ces super-réseaux considérant un empilement aléatoire de blocs cristallins permet la simulation des courbes de diffraction obtenues expérimentalement. Enfin, les premières intégrations des super-réseaux (GeTe)2/(Sb2Te3)m dans des dispositifs mémoires mettent en évidence une réduction importante des courants de programmation jusqu’à 4 fois inférieurs à une PCM et avec une endurance dépassant les 10 millions cycles
In order to satisfy the demand for more and more efficient memory in computer systems, new technologies have been developed. Among the latter resistive phase-change memories (PCM) exhibit capacities and sufficient maturity to achieve the so-called new SCM (for Storage Class Memory) devices as evidenced by the recent commercialization of Optane products by INTEL®. Nevertheless, PCM still require strong electrical consumption limiting their performance. Integration of (GeTe)2/(Sb2Te3)m superlattices in so-called iPCM (for interfacial Phase Change Memory) was shown to permit a significant decrease in programming currents. However, the switching mechanism of this memory and the structure of the material in its two resistance states are still under debate. The aim of this thesis is therefore to deposit crystalline (GeTe)2/(Sb2Te3)m (m=1,2,4 et 8) superlattices, to determine their structure and to integrate them into memory devices. GeTe and Sb2Te3 materials are alternately deposited by means of sputtering in an industrial deposition tool to perform van der Waals epitaxy of these superlattices. Stoichiometric superlattices with the desired periodicity and with an orientation of the (0 0 l) crystalline planes parallel to the surface of the substrate are obtained by innovative co-sputtering of Sb2Te3 and Te targets during Sb2Te3 deposition. A description of the local atomic order of superlattices is then carried out by studying HAADF-STEM images coupled to simulations. Intermixing between GeTe and Sb2Te3 deposited layers is thus revealed, leading to the local formation of rhombohedral GexSbyTez. Quantitative measurements of the Ge/Sb atomic plans occupation in further confirm the phenomenon. A long-range order structural model of superlattices by means of random stacking of crystalline blocks allows the simulation of experimental diffraction curves. Finally, the first integrations of (GeTe)2/(Sb2Te3)m (with m=1,2,4 et 8) superlattices in devices demonstrate a programming current up to 4 times lower than a PCM reference with an endurance exceeding 10 millions cycles

Abstract:
The future of computing lies with distributed systems, i.e. a network of workstations controlled by a modern distributed operating system. By supporting load balancing and parallel execution, the overall performance of a distributed system can be improved dramatically. Process migration, the act of moving a running process from a highly loaded machine to a lightly loaded machine, could be used to support load balancing, parallel execution, reliability etc. This thesis identifies the problems past process migration facilities have had and determines the possible differing strategies that can be used to resolve these problems. The result of this analysis has led to a new design philosophy. This philosophy requires the design of a process migration facility and the design of an operating system to be conducted in parallel. Modern distributed operating systems follow the microkernel and client/server paradigms. Applying these design paradigms, in conjunction with the requirements of both process migration and a distributed operating system, results in a system where each resource is controlled by a separate server process. However, a process is a complex resource composed of simple resources such as data structures, an address space and communication state. For this reason, a process migration facility does not directly migrate the resources of a process. Instead, it requests the appropriate servers to transfer the resources. This novel solution yields a modular, high performance facility that is easy to create, debug and maintain. Furthermore, the design easily incorporates providing multiple migration strategies. In order to verify the validity of this design, a process migration facility was developed and tested within RHODOS (ResearcH Oriented Distributed Operating System). RHODOS is a modern microkernel and client/server based distributed operating system. In RHODOS, a process is composed of at least three separate resources: process state - maintained by a process manager, address space - maintained by a memory manager and communication state - maintained by an InterProcess Communication Manager (IPCM). The RHODOS multiple strategy migration manager utilises the services of the process, memory and IPC Managers to migrate the resources of a process. Performance testing of this facility indicates that this design is as fast or better than existing systems which use faster hardware. Furthermore, by studying the results of the performance test ing, the conditions under which a particular strategy should be employed have been identified. This thesis also addresses heterogeneous process migration. The current trend is to have islands of homogeneous workstations amid a sea of heterogeneity. From this situation and the current literature on the topic, heterogeneous process migration can be seen as too inefficient for general use. Instead, only homogeneous workstations should be used for process migration. This implies a need to locate homogeneous workstations. Entities called traders, which store and disseminate knowledge about the resources of several workstations, should be used to provide resource discovery. Resource discovery will enable the detection of homogeneous workstations to which processes can be migrated.

Abstract:
Smart materials have been widely used for control actuation. A robotic hand can be equipped with artificial tendons and sensors for the operation of its various joints mimicking human-hand motions. The motors in the robotic hand could be replaced with novel electroactive-polymer (EAP) actuators. In the three-finger gripper proposed in this paper, each finger can be actuated individually so that dexterous handling is possible, allowing precise manipulation. In this dissertation, a microscale position-control system using a novel EAP is presented. A third-order model was developed based on the system identification of the EAP actuator with an AutoRegresive Moving Average with eXogenous input (ARMAX) method using a chirp signal input from 0.01 Hz to 1 Hz limited to 7 ± V. With the developed plant model, a digital PID (proportional-integral-derivative) controller was designed with an integrator anti-windup scheme. Test results on macro (0.8-mm) and micro (50-μm) step responses of the EAP actuator are provided in this dissertation and its position tracking capability is demonstrated. The overshoot decreased from 79.7% to 37.1%, and the control effort decreased by 16.3%. The settling time decreased from 1.79 s to 1.61 s. The controller with the anti-windup scheme effectively reduced the degradation in the system performance due to actuator saturation. EAP microgrippers based on the control scheme presented in this paper will have significant applications including picking-and-placing micro-sized objects or as medical instruments. To develop model-based control laws, we introduced an approximated linear model that represents the electromechanical behavior of the gripper fingers. Several chirp voltage signal inputs were applied to excite the IPMC (ionic polymer metal composite) fingers in the interesting frequency range of [0.01 Hz, 5 Hz] for 40 s at a sampling frequency of 250 Hz. The approximated linear Box-Jenkins (BJ) model was well matched with the model obtained using a stochastic power-spectral method. With feedback control, the large overshoot, rise time, and settling time associated with the inherent material properties were reduced. The motions of the IPMC fingers in the microgripper were coordinated to pick, move, and release a macro- or micro-part. The precise manipulation of this three-finger gripper was successfully demonstrated with experimental closed-loop responses.

Abstract:
Ionic Polymer Metal Composite (IPMC) is a class of electroactive polymer , that is receiving great attention due to its advantages of large bending deflection, low power consumption and driving voltage. Although there is still no commercial application of IPMC, it has been actively investigated by researchers for the past decade. The IPMC has been identified as a potential material to be used in the specific application of sensor and/or actuation, such as microgripper and micropump. This research deals with the characterisation of small scale IPMC with the ultimate objective to develop a simple microgripper to demonstrate the ability of the IPMC to grasp a micro object. A vision system has been developed to perform image processing to measure the displacement of IPMC. New algorithms of edge detection and displacement measurement have been introduced to characterise the IPMC. Comparison between laser sensor measurements and vision systems measurement has been carried out and the results showed that the vision system is a reliable measurement. Characterisation of small scale IPMC is carried out to prove the claim that miniaturization of IPMC is possible without degrading its performance. The characterisation of the IPMC actuator is divided into two major works - the displacement and blocked force measurements. The results showed that small scale characteristics are in line with the results that have been published by other researchers for larger scale of IPMC, hence supported the claim. The dynamic sensory behaviour of the IPMC has also been characterised. The results showed that the sensor functions are better in terms of producing consistent output signals when it is dehydrated. With such finding, the possibility of using the IPMC as the actuator and sensor at the same time for micro gripper application is not promising because the actuator needs to be fully hydrated in order to work better while the sensor is working better in a dehydrated condition. The final part in this research work is to develop a simple micro gripper. A two-finger microgripper with size of lOmm x 2rnrn x O.2mm is controlled by a vision feedback system to grasp small objects. For a demonstration purposes, an object with diameter of lmm was successfully grasped in 4.6 seconds.

Abstract:
An ionic polymer-metal composite (IPMC) is an electroactive material that bends when electrically stimulated and generates electric current when bent. In this paper we investigate a coupled IPMC sensor-actuator using both the sensing and actuation properties of these electroactive materials. We describe the design of a coupled IPMC sensor-actuator, the feedback controller and the experimental evaluation of the system. Experimental results show the feasibility of closed-loop control of IPMC actuator with a mechanically coupled IPMC sensor.

Abstract:
An ionic polymer-metal composite (IPMC) consisting of a thin perfuorinated ionomer membrane, electrodes plated on both faces, undergoes large bending motion when a small electric field is applied across its thickness in a hydrated state. On the other hand, when small load is applied on IPMC, the electric field is induced in the polymer membrane depending on the magnitude of loading. The characteristics of IPMC are ease of miniaturization, low density and mechanical flexibility. Therefore, it is considered to have a wide range of applications from MEMS sensors to actuators. In this paper, we developed the fabrication process of IPMC actuator with palladium electrodes, which have lower stiffness than the conventional IPMC actuator with Au or Pt electrodes. The deformation of IPMC actuator is evaluated under various solvents, various temperatures, and various frequencies of input voltages. We developed the numerical model of IPMC actuator that can change the solution temperature and the ion species and compared the simulation results to the experimental results.

Abstract:
An ionic polymer-metal composite (IPMC) sensor typically consists of a thin ion-exchange membrane with electrodes on both surfaces. Such IPMC sensors respond to deflections in the beam-bending directions only and thus are considered one-dimensional. In this paper, a novel IPMC sensor capable of two-dimensional sensing is presented. This tubular thin-wall IPMC has one common inner electrode and four outer electrodes, which form four routes of common-ground outputs. The fabrication method is reported along with the sensor package. A custom-designed experimental setup, which provides dynamic tip bending with adjustable orientations and controlled bending amplitude, is used to characterize the sensor response (short-circuit current) to the 2D mechanical stimulus in air. Based on the characterization results, we further model the proposed 2D tubular IPMC sensor by treating pairs of infinitesimal portion of tube wall as one-dimensional IPMC sensors and integrating them around the tube. Experimental results show that the fabricated IPMC sensor responds to omnidirectional stimulus within the cross-section plane and the proposed model captures well the sensor responses, indicating that this tubular IPMC sensor can be potentially used for 2D flow and displacement sensing.
