Abstract. In this work we present near-field wireless sensing of single and multiple open-ended micro coils using an electrically small loop antenna. Wirelessly characterized parameters of open-ended micro coils include its resonance frequency, quality factor and inductance. Moreover a wireless frequency-dependent analytical model was developed. Micro coil inductance was extracted from the wirelessly measured signal using a constraint-based least-squares approach. Wireless measurements and analytical fit of micro coils are in strong agreement which validates the analytical model. Finite element method (FEM) simulations of the coupled system were done in COMSOL Multiphysics.

Abstract:
This project focuses on wireless power transmission (WPT). More specifically, the use of inductive coupling with resonance. The resonance phenomenon makes the transfer of power more efficient, through matching the inductive and capacitive reactances thus eliminating the reactive losses. A wireless smartphone charger has been built with this method for demonstration, and some tests were performed. The charger consisted of a primary “transmitting circuit” and a secondary “receiving circuit”. The built charger did not achieve full resonance, but it achieved longer wireless transmission distance compared to that of a commercial wireless phone charger. The first experiment confirmed the DC/AC characteristics of the transmitting circuit, and the ability for the voltage to oscillate at a higher level than the input voltage. The voltage oscillated at 45kHz. The second experiment confirmed the AC/DC characteristics of the receiving circuit, and the ability to regulate the voltage to a constant 5V. The minimum required input voltage for the receiving circuit, to achieve a constant 5V output, was approximately 6V. Frequencies from 100Hz to 350kHz were tested and it had no severe impact on stability of the output voltage. The third and last test used both circuits, and showed the relationship between input voltage and transmission distance. The maximum distance achieved for the complete device was ~4.3cm at an input voltage of ~20V. When having the coils touch (Transmission distance ~0cm), the minimum required voltage was 6.6V, whereas a commercial wireless charger needs 5V.

Abstract:

Exploitation of wireless sensor networks (WSNs) in ubiquitous computing environments is continuously increasing for gathering data. Contemporary distributed software systems on WSNs for pragmatic business applications have become extremely adaptive, dynamic, heterogeneous and large scaled. Management of such system is not trivial to fulfil these features, leading to more and more complex management and configuration. Along with encompassing state of art and novel techniques for such diversely dynamic system, in this thesis two alternative techniques namely “task initiation by command” and “run-time task deployment and processing” are compared, for such system’s setup and configuration. Both techniques have their own pros and cons which makes them suitable according to the requirements and contextual situations. A lot of effort has been put to make WSNs more and more efficient in terms of computations and power consumption. Hence comparative analysis of both techniques used in this report to setup and configure WSN can be a benchmark to lead towards most appropriate solution to compensate the need of efficient energy and resource consumption.Both alternative schemes are implemented to setup WSN on Sun Microsystems sunSPOT (Small Programmable Object Technology) sensor nodes which are embedded microcontrollers and programmed them in java (j2me). It performs radio communication between wireless sensors and host via sink node also called base station, along with over the air run-time management of sensors. SunSPOTs built in libraries and KSN libraries are used to implement these alternatives and compare the memory footprint, communication pattern and energy consumption.Exploitation of wireless sensor networks (WSNs) in ubiquitous computing environments is continuously increasing for gathering data.

Abstract:

This master's thesis will investigate some of the technological solutions available for the construction of a backbone for a wireless citywide network (CWN), such as Wireless Trondheim, and a special attention is given to the possible advantages of using infrastructure already in place. There are several different technologies which can be used as a backbone for the wireless CWN, and in this thesis strengths and weaknesses of the various solutions will be discussed. Some requirements, such as scalability to handle increased capacity demand from future access technologies, may be more important to satisfy than others, and the discussion will see how this might rule out or favor some technology choices. In addition to demands from regular traffic to be carried in the network, also research traffic should be allowed. It is discussed how different requirements as a consequence of this research traffic will set limitations to which technology to use. While the performance of each of the technologies are relatively constant for all cases and easy to determine, the cost of using the different technologies is not. For this reason most effort is put into the analysis of this decision factor. Different possible scenarios are introduced, and the costs of using various technologies in the different scenarios are calculated. The results from the calculations are then discussed in more detail, and an important part of this discussion is sensitivity analysis. The values for several of the parameters used in the calculations will be changed, and the various analyses show how the change of one parameter will affect the result of the calculations. Based on the calculation results and the discussion of the results, some principles which can be used as guidelines in planning and deployment of a backbone for a wireless CWN will be suggested.

Abstract:
This dissertation considers wireless sensor networks (WSNs) operating in severe environments where energy efficiency and security are important factors. This main aim of this research is to improve routing protocols in WSNs to ensure efficient energy usage and protect against attacks (especially energy draining attacks) targeting WSNs. An enhancement of the existing AODV (Ad hoc On-Demand Distance Vector) routing protocol for energy efficiency, called AODV-Energy Harvesting Aware (AODVEHA), is proposed and evaluated. It not only inherits the advantages of AODV which are well suited to ad hoc networks, but also makes use of the energy harvesting capability of sensor nodes in the network. In addition to the investigation of energy efficiency, another routing protocol called Secure and Energy Aware Routing Protocol (ETARP) designed for energy efficiency and security of WSNs is presented. The key part of the ETARP is route selection based on utility theory, which is a novel approach to simultaneously factor energy efficiency and trustworthiness of routes in the routing protocol. Finally, this dissertation proposes a routing protocol to protect against a specific type of resource depletion attack called Vampire attacks. The proposed resource-conserving protection against energy draining (RCPED) protocol is independent of cryptographic methods, which brings advantage of less energy cost and hardware requirement. RCPED collaborates with existing routing protocols, detects abnormal sign of Vampire attacks and determines the possible attackers. Then routes are discovered and selected on the basis of maximum priority, where the priority that reflects the energy efficiency and safety level of route is calculated by means of Analytic Hierarchy Process (AHP). The proposed analytic model for the aforementioned routing solutions are verified by simulations. Simulations results validate the improvements of proposed routing approaches in terms of better energy efficiency and guarantee of security.

Abstract:
This paper presents a wireless ultrasound sensor that uses frequency conversion to convert the ultrasound signal to a microwave signal and transmit it directly without digitization. Constructed from a few passive microwave components, the sensor is able to sense, modulate, and transmit the full waveform of ultrasound signals wirelessly without requiring any local power source. The principle of operation of the unpowered wireless ultrasound sensor is described first. Implementation of the sensor and the sensor interrogation unit using commercially-available antennas and microwave components is described in detail. Validation of the sensing system using an ultrasound pitch-catch system and the power analysis model of the system are also presented.

Abstract:
A sensor module that integrates a thin film PVDF piezoelectric strain sensor and a wireless data processing/transmitting platform has been designed and implemented for wireless monitoring of the feed force in the slot end milling process. The module, which is mounted on the tool shank, measures the dynamic strain produced in the tool and transmits data wirelessly to the receiver connected to a data acquisition computer. A first principles model based on the Euler-Bernoulli beam theory and constitutive equations of the piezoelectric sensor material is used to transform the wirelessly obtained data into the feed force acting on the tool in a slot milling operation. The wireless PVDF sensor signal is found to compare well with the expected (or theoretical) sensor signal computed from the measured feed force in slot milling experiments.

Abstract:
Wireless Electric Transfer (WET) is a cutting-edge technology that allows power to be transmitted without physical contact. Most power technology is being converted to wireless technology by various methods as technology advances. Even if electric vehicles and plug-in hybrids are relatively new and viable, it is insufficient to keep the power source unplugged a night before. When an electric car park in a designated parking area with a transmitter circuit in place, charging will begin automatically. The Inductively Coupled Power Transfer System (ICPT) was discovered to be an excellent way for charging electric automobiles wirelessly after a study of a few wireless charging systems (Electric Vehicles). Bidirectional IPT (Inductively Coupled Power Transfer System) presented in this paper is suitable for Vehicle to Grid (V2G) systems. For Electric Vehicle charging, this Bidirectional Wireless Power Transfer is a dependable, powerful, and effective technology. Wireless power approaches comprise two classes: non-radiative and radiative. The study will also improve the system’s practicality, dependability, and efficiency.

Abstract:
Artificial limb control is an active area of research, and the control of prosthetic devices using electromyographic (EMG) interfaces is well established. The authors have previously performed a feasibility study which demonstrated that wireless nerve control of a prosthetic device is possible. This is critical for injuries that result in the loss of muscle which prevent EMG control. The purpose of this study is to extend the authors’ current research by providing enhancements to the system designed in the feasibility study. The objective of this current study is to take simulated nerve signals and transform them into corresponding positional motion control realized by a servo motor. The system designed has four functioning blocks: artificial nerve signal generation, wireless transmitter, wireless receiver, and servo motor. The artificial nerve generator used a PIC microcontroller to simulate and apply the signals directly to the wireless transmitter. A one-byte message, that indicated when the appropriate signal characteristics were met, was wirelessly transmitted. After receiving the message, the wireless receiver sent a corresponding pulse-width modulated (PWM) signal to the servo motor for positional control. Various input signal combinations were used to test the system.

Abstract:
All the world now is depending on networks to share information between the users, where different data types are transferred wirelessly from network to network. Using wireless LANs are important to connect the users and share the data, these Wireless LANs have different types of obstacles that affect the data sharing or the wireless signal, such as, compatibility wireless protocol types, range coverage, walls penetration, moving devices, different routing protocols, data transferred types, weak signal, and many more. In this paper a practical analysis will be made to the latest IEEE 802.11ax wireless protocol to be compared with two types of Wi-Fi booster’s networks, Mesh and Extender Wi-Fi, while transferring 4k video size data rate, inside a room and on different rooms for wall penetration analysis, while measuring the throughput, delay, and signal strength metrics. The main importance of this paper is to give a more practical understanding and avoid the main problems of using the wireless protocol 802.11ax in different network types.

Abstract:
Abstract Industrial wireless is essential to achieve the vision of future manufacturing systems which are highly dynamic and reconfigurable, and communicate large amounts of data. Main challenges of wireless deployment include the stochastic nature of the wireless channels and the harsh industrial transmission environment. In this work, a typical two-dimensional gantry system is controlled by a local controller which receives G-code commands wirelessly over a Wi-Fi network. The industrial wireless channel is replicated using a radio frequency (RF) channel emulator where various scenarios are considered and various wireless channel parameters are studied. The movement of the gantry system tool is tracked using a vision tracking system to quantify the impact of the wireless channel on the system performance. Numerical results are presented including the total run time of an industrial process and the dwell times at various positions through the process.

Abstract:
The concept of wireless passive strain sensors has been introduced in the last few years for applications such as structural health monitoring. This study investigates the use of circular microstrip patch antenna (CMPA) sensors for wireless passive measurement of strain. The strain induced in an aluminium plate was measured wirelessly up to 5 cm away from the sensor using a CMPA made from commercial FR4 substrate, and at a distance up to 20 cm using a CMPA made from Rogers® RT/duroid 6010™. These results show the substrate of antennas is one of the factors affecting the interrogation distance. The interrogation distance between the sensor and the patch antenna was improved significantly using the Rogers® substrate.

Abstract:
Wireless ultrasound inspections using Piezoelectric Wafer Active Sensors (PWAS) are attractive for Structural Health Monitoring (SHM). However, the impedance mismatch between the PWAS and the wireless transponder reduces the wirelessly transmitted signal strength. Electrical Impedance Matching (EIM) circuit can be introduced to maximize the power transmission between the PWAS and the wireless transponder. This paper discusses the wireless excitation of ultrasound as well as the design, simulation, and characterization of the EIM networks for PWAS. To maximize power transmission, a two port EIM network was developed using a computerized smith chart. The equivalent circuit of the PWAS and the EIM network were then combined to establish the equivalent circuit of the matched transducer. Computer simulations were carried out to evaluate the gain, the bandwidth, and the sensitivity of the EIM networks. Two-port EIM networks were implemented for both the actuator and the sensor in an ultrasound pitch-catch inspection system. The performance of the pitch-catch systems with and without the EIM networks was compared. Detailed analysis, simulation, hardware implementation, and measurement results are presented.

Abstract:
A compact wireless strain sensor using a Frequency Modulation (FM) technique is proposed. The sensor employs a conventional resistive strain gauge such that the resistance changes as the measured structure is mechanically strained. When the strain gauge is connected to a frequency modulation circuit, the change in the resistance appears as a frequency shift in the output signal that is transmitted wirelessly to a remote station. The received signal is then demodulated and the buried strain measurement data can be retrieved. Using this technique, a dynamic strain measurement is possible without any wire connection between the sensing point and the measurement equipment. This type of sensors have numerous applications in the strain or vibration measurement of moving or rotating structures such as fans on a turbine engine. The proposed concept of the wireless strain sensor is experimentally demonstrated by measuring vibration of a cantilevered beam with a wired transmission of the measurement data from the transmitter to the receiver.

Abstract:
The measurement of posture, loading conditions, and physiological parameters during physical activity is key in human performance monitoring and assessment. Of particular interest in this study is the monitoring of these parameters during high intensity activities associated with firefighting. The objective is to capture various walking cycles using nanocomposite pressure sensors built into the backpack-type harnesses of a Self-Contained Breathing Apparatus (SCBA) unit. It was hypothesized that the sensor’s high stability, linearity, and sensitivity would allow this sensor to be used for human posture and activity monitoring. First, nanocomposite sensors were prepared by integrating piezoresistive graphene nanosheet thin films between elastomer layers. Two sensors were then integrated with the SCBA harnesses and mounted at symmetric locations to capture gait and respiration cycles. Second, a small, portable, wireless data acquisition unit was developed to non-intrusively monitor up to eight sensors and wirelessly transmit the data for external data storage and analysis. This sensing node included analog signal conditioning circuits alongside an ARM based microprocessor for analog to digital conversion, signal processing, and wireless transmission. Third, human participant tests were performed while wearing these harnesses. The participants performed various low intensity walking and respiratory cycles. The results confirmed that the wireless sensing unit was able to reliably acquire sensor measurements, while the sensing streams also exhibited unique features indicative of different activities and postures.
