Full textLa electrónica impresa permite la impresión de dispositivos electrónicos ofreciendo una gran ventaja en comparación con procesos tradicionales o microelectrónica debido a su versatilidad, bajo coste de producción y posibilidad de generar circuitos flexibles. La selección del método de impresión es crucial a la hora de alcanzar un buen resultado y depende de los materiales necesarios y de los requerimientos dimensionales y funcionales. En esta tesis, la serigrafía, una técnica de impresión fiable y consolidada en la industria desde hace años, es comparada con la inyección de tinta (inkjet), que aún muestra un gran desafío en cuanto a rendimiento y reproducibilidad. Cada tecnología ofrece posibilidades diferentes en complejidad, resolución, grosor de capas y materiales. En la primera parte de la tesis se describen la inyección de tinta y la serigrafía en términos de fundamentos, parámetros y formulación de materiales. En la segunda parte, el potencial de ambas tecnologías se ha estudiado en diferentes escenarios mediante la fabricación de diversos dispositivos electrónicos. En el estudio de la fiabilidad y robustez de plataformas sensoras flexibles se ha encontrado una relación directa entre la morfología de la plata depositada y su causa de fallo en funcionamiento prolongado. La sinterización de las nanoparticulas depositadas por inkjet forma una capa lisa y con poca porosidad que evita parcialmente la corrosión, a diferencia de la pasta de plata impresa por serigrafía. Sin embargo, su bajo provoca defectos puntuales que puede causar puntos calientes. También, inkjet se ha empleado para la síntesis de precursores de la capa absorbente para celdas solares de capa fina. Se ha formulado una tinta de precursores de cobre, zinc, estaño y azufre (CZTS) para la formación de kesterita obteniéndose celdas de 6.55% de eficiencia, siendo la más alta reportada hasta la fecha utilizando este tipo de absorbente y tecnología. Sin embargo, en aplicaciones donde la conductividad es crucial para altas prestaciones, como en radiofrecuencia, queda patente la desventaja del inkjet sobre la serigrafía, donde su escaso grosor de capa es un claro hándicap para la obtención de conductividades elevadas. Dicho factor limitante es abordado con la combinación de la inyección de tinta con la deposición química (electroless) de níquel y cobre, consiguiéndose inductores equivalentes a los serigrafiados.

Of the various types of fuel cells, Polymer Electrolyte Fuel Cells (PEFCs) have already been demonstrated in transportation appliances from light-duty vehicles to buses and in portable appliances including laptops and cell phones. A key component of a PEFC is its platinum electrocatalyst. With an estimated 75% of the world’s platinum reserves and resources in South Africa, local development of this technology will allow South Africa to become a major player in the growing hydrogen economy. This project therefore forms part of the Department of Science and Technologies strategy, to develop fuel cell technology in South Africa. More specifically, this study aims to contribute to the development of membrane electrode assembly (MEA) platform technology at the HySA/Catalysis Centre. In order to achieve this goal, a catalyst coated membrane (CCM) fabrication procedure was implemented using a newly acquired screen printer. In this procedure, catalyst ink is forced through a mesh onto a substrate, where it can then be transferred to a membrane via decal transfer to form a CCM. Two gas diffusions layers can then be placed on either side of the CCM forming a 5-layered MEA. Characterisation techniques of the catalyst ink, CCM and 5-layered MEA were successfully implemented such that future researchers can expand on the ideas. Catalyst inks with varying amounts of isopropanol, 1,2-propanediol and water were screened for their suitability for screen printing. In particular the catalyst ink rheology required for a smooth and even printed surface was determined for a given screen and squeegee combination. With all the established steps in pace, screen printing proved to be a fast and reliable approach for CCM fabrication with potential for future scale up and commercialisation. The fabricated CCMs performed on a par with a commercial Ion Power CCM, but under performed in comparison to a commercial Johnson Matthey (JM) MEA. Possible reasons for this include improved materials in the JM MEA and cell conditions favouring the JM MEA. Future projects which specifically arise from this work entail an investigation into the water management of the fuel cell environment at HySA/Catalysis, as well as a modification of the various steps in order to optimise the process and in doing so manufacture commercially viable MEAs.

Full textLinköpings Universitet och Acreo AB i Norrköping bedriver ett forskningssamarbete rörande organisk elektrokemisk elektronik och det man kallar papperselektronik. Målet på Acreo är att kunna trycka denna typ av elektronik med snabba trycktekniker så som offset- eller flexotryck. Idag görs de flesta demonstratorer och prototyper, baserade på denna typ av elektrokemisk elektronik, med manuella och subtraktiva mönstringsmetoder. Det skulle vara intressant att hitta fler verktyg och automatiserade tekniker som kan underlätta detta arbete. Målet med detta examensarbete har varit att utvärdera vilken potential bläckstråleteknik respektive screentryck har som tillverkningsmetoder för organiska elektrokemiska elektroniksystem samt att jämföra de båda teknikernas för- och nackdelar. Vad gäller bläckstråletekniken, så ingick även i uppgiften att modifiera en bläckstråleskrivare avsedd för kontor/hemmabruk för att möjliggöra tryckning av de två grundläggande materialen inom organisk elektrokemisk elektronik - den konjugerade polymeren PEDOT och en elektrolyt.
I denna uppsats rapporteras om hur en procedur för produktion av elektrokemisk elektronik har utvecklats. Världens första elektrokemiska transistor som producerats helt med bläckstråleteknik presenteras tillsammans med fullt fungerande implementeringar i logiska kretsar. Karaktärisering av filmer, komponenter och kretsar som producerats med bläckstråle- och screentrycksteknik har legat till grund för den utvärdering och jämförelse som har gjorts av teknikerna. Resultaten ser lovande ut och kan motivera vidare utveckling av bläckstrålesystem för produktion av prototyper och mindre serier. En kombination av de båda nämnda teknikerna är också ett tänkbart alternativ för småskalig tillverkning.
Linköping University and the research institute Acreo AB in Norrköping are in collaboration conducting research on organic electrochemical electronic devices. Acreo is pushing the development of high-speed reel-to-reel printing of this type of electronics. Today, most demonstrators and prototypes are made using manual, subtractive patterning methods. More tools, simplifying this work, are of interest. The purpose of this thesis work was to evaluate the potential of both inkjet and screen printing as manufacturing tools of electrochemical devices and to conduct a comparative study of these two additive patterning technologies. The work on inkjet printing included the modification of a commercially available desktop inkjet printer in order to print the conjugated polymer PEDOT and an electrolyte solution - these are the two basic components of organic electrochemical devices. For screen printing, existing equipment at Acreo AB was employed for device production.
In this report the successful development of a simple system and procedure for the inkjet printing of organic electrochemical devices is described. The first all-inkjet printed electrochemical transistor (ECT) and fully functional implementations of these ECTs in printed electrochemical logical circuits are presented.
The characterization of inkjet and screen printed devices has, along with an evaluation of how suitable the two printing procedures are for prototype production, been the foundation of the comparison of the two printing technologies.
The results are promising and should encourage further effort to develop a more complete and easily controlled inkjet system for this application. At this stage of development, a combination of the two technologies seems like an efficient approach.

A necessidade de métodos mais versáteis para a mensuração e monitoramento dos níveis séricos de lipídios tem estimulado a produção de uma grande variedade de novos métodos analíticos. O presente trabalho mostra o desenvolvimento de um biossensor monoenzimático para detecção de triglicerídeos empregando a tecnologia de Screenprinting através da qual, foram impressos os eletrodos de referência (Ag/AgCl) e o de trabalho contendo uma mistura de carbono e quitosana. A lipase foi imobilizada por adsorção no eletrodo de trabalho. A lipase solúvel, usando pNPM, apresentou pH ótimo de 8 e temperatura ótima de 32,5°C, mantendo cerca de 78,5% da atividade máxima a 25°C (temperatura operacional do biossensor). O Km e Vmáx para a lipase solúvel em relação ao pNPM foram de 0,95 mM e 25,51 U/mg proteína, respectivamente. No biossensor desenvolvido com apenas lipase imobilizada, usando trioleína como substrato, foram de 0,148 mM e 262,21 μA/s e 0,304 mM e 85,07 μA/s para a lipase solúvel e TIP sem enzima. Os resultados mostraram linearidade nas respostas de correntes para trioleína (0,25mM 2mM), atestando a viabilidade do biossensor desenvolvido, utilizando unicamente a lipase imobilizada na superfície do eletrodo de trabalho, podendo ser empregado eficientemente para a detecção de triglicerídeos

Full textPhotovoltaic systems present themselves as an excellent alternative for clean energy production. To reach large applications, obstructions as high silicon prices must be overcome. Solar concentration systems are a potential solution since silicon is replaced by cheaper material (like mirrors or lenses). Nevertheless, there are still many issues and challenges yet to overcome. One of these challenges is the economic cost of the solar cells, since the CPV systems need to integrate expensive high efficiency solar cells specially designed to operate at high levels of radiation. Thus, it is necessary to explore new approaches. In this thesis presents a study of the potential of the screen-printed silicon solar cells to integrate the CPV systems, concretely the HSUN system. Two solar cells, conventional 1Sun and conventional 15Suns, were analyzed and integrated in the HSUN sub-receivers, in order to understand their behavior under several levels of concentration and when integrated in series in sub-receivers. After the first part of the experimental campaign (electrical characterization of solar cells) it was concluded that the conventional standard silicon solar cells are unsustainable for use in the HSUN system (which operates a 15 suns), since these solar cells only work properly up to a concentration of 5 suns. Regarding the Upgraded 1-sun silicon solar cells, the results were satisfactory regarding their behavior under concentration, until a concentration level of 20 suns. In the second part of the experimental campaign, the Upgraded 1-sun solar cells were integrated in the HSUN sub-receivers and their behavior was analyzed. The results taking from this part of the experimental campaign prove the good performance of the Upgraded solar cells and that their performance is unaffected by their integration in the sub-receivers. Associated to this part of the experiments, was also performed the optimization of the mounting process of the sub-receivers. This optimization provided a faster process with a lower probability of damaging the solar cells. To a complete study of the potential of these solar cells, it is important to take into account the economic viability of the solar cells. Comparing the cost-efficiency of the standard conventional solar cells, the LGBC solar cells (cells used actually in the HSUN system) and the Upgraded 1-sun solar cells, it was concluded that the solar cells more viable up to a concentration level of 24 suns are the Upgraded 1-sun solar cells, being that from this concentration level the LGBC solar cells solar cells present themselves as the most viable. Therefore, and taking into account all the work developed along this thesis, it was concluded that the most cost-efficient solar cells to integrate the HSUN system are the conventional solar cells with some characteristics optimized for the required concentration levels.

“Cloud Printing” has extended from the web-to-print, and has become a new trend of printing industry all over the world since 2007. Cloud Printing is commercial activities for trading of printing products or service through the internet. Most of Asian screen printers still use traditional processes to print orders. Comparing to the printers in U.S. or Europe countries, these screen printers in Taiwan seem not so active in the development of Cloud Printing. Under the influence of digitalization, it will be very important for them to pay attention how to provide Cloud Printing service. To understand the needs, key elements, criteria, and necessity of a profitable customized Cloud Printing platform, this study conducted content analyses on major successful cloud printing service websites in different countries and Taiwan, in addition to qualitative approaches, a questionnaire survey on Taiwanese screen printers and customers was conducted to fulfill the objectives of the study. To explore how Taiwanese screen printers and consumers view the must-have requirements and understand the bottlenecks and difficulties encountered for Taiwanese screen printers, and to comprehend the web structure and important functional items in the process of establishing and maintaining a personalized Cloud Printing platform. This study disclosed Taiwanese screen printers need more online sofware technology and knowledge in the development of Cloud Printing, and provide consumers with the information about how to use the design editor help consumers easy to create and print the personalized products. Hope this study will elevate competitiveness of traditional screen printing enterprise and create maximal utility for the conventional screen printers, and help screen printing enterprise develop a successful me-commerce Cloud Printing platform usefully for consumers.

Printing industry is enhanced to the production and service industries. The use of advanced printing technology gives new life to RFID technology to force the printing industry and the electronics industry more closely together. This makes the RFID tags to printers, printing materials and equipment suppliers to raise the new demand. In the mean time, it also opens a new product line, a new profit growth and new markets. Because the passive RFID tag printing of "conductive ink" when its printed materials need to use the high price of silver. This leads the RDIF tag cannot reduce the cost. This study used true-experimental research method by using the screen printing. The different size of the halftone dots is used to adjust the amount of conductive ink to save the amount of conductive ink reach RFID tags cost down. But still maintain the communication effectiveness of RFID, and then further accelerate the market development of RFID tags. The experiment used the different printing resolutions, different papers and different halftone dot sizes (dots and dots must be connected without breaking). After screen printing is completed, put the strap IC chip onto the RFID tags and measure the effective distance of the RFID tag. The results of the research: is smaller print resolution, the higher the amount of conductive ink; the larger the print halftone dot size (the closer to the line art) the better reading distance. However, the amount of ink and use the reading distance must find its place point. The saving of the ink becomes meaningful and significant. Therefore, we do believe that by changing the halftone dot size is a feasible solution and the cost of the RFID tag can be reduced. Furthermore, by using the same RFID antenna design, the use of different dot sizes should be have different distances of the RFID tag for the different end applications.

Screen printing is no longer the industry with relative backward technologies. With the developments of the modern technologies, screen printing has become one of the major production processes in 3C products, especially on the circuit printing. However, due to the unfamiliar with screen printing’s variables, people blames on it while problems occurs during the printing production. The problems always caused by user try to change screen variables in the low-cost situation that makes screen manufacture difficult to maintain quality. Those changes even violate basic Screen printing restrictions that want to improve the productivity and precision often futile. This study is focus on the improvement of the composite screen structure to produce more accurate and stable screen tension. And result a better quality and more accurate screen printing results. According to the study results, polygonal composite web version produced better tension quality than the general square composite web version. The polygonal composite web break itself the mesh tension limit and shorten the net in time, improve the stability of the net in time to save break mesh screen costs. It also maintains tension for longer time. The higher path accuracy and enhance yield.
