Resumen
A piezoelectric energy harvesting (PEH) system can harvest electrical energy from ambient vibration energy. In a PEH system, the interface rectifier circuit is critical because it converts AC from the output of piezoelectric harvester to DC that can power the load. Hence, improving the efficiency of the interface circuit can directly increase the efficiency of the entire PEH system; consequently, more power can be harvested. Commonly used interface circuits in PEH systems, such as full-bridge and voltage- doubler rectifiers,lead to relatively simple circuit implementations but they show seriou

This thesis focuses on the use of surface modifiers as tools for probing and/or controlling interfaces. Surface modification of transparent conducting oxides (TCOs) with organic and organometallic modifiers can be used as a tool for mediating interfacial energetics as well as probing the kinetics of charge-transfer at the metal oxide/organic interface. The synthetic tunability of these modifiers allows us to design molecules based on various parameters, which include the nature of the binding, spacer, and terminal groups.

Resumen
Isotropically conductive adhesives (ICAs) are promising as a lead-free interconnect material; However, ICAs have a higher resistivity compared to tin/lead solder. The higher resistivity of ICAs results from the large contact resistance between conductive fillers. Several novel approaches to engineer the interface between electrically conductive fillers were studied to develop highly conductive ICAs. Shown in this dissertation are three methodologies to reduce contact resistance: low temperature sintering, fast sintering and in-situ reduction. Furthermore, two approaches, surface modification a

The requirements of the system of characterization depend on the application.

Resumen
碩士<br>國立清華大學<br>電機工程學系<br>98<br>Many applications use the electronic nose (Enose) system, such as environmental monitoring, food processing, pollution measurement and medical diagnosis. The ability to monitor and identify various chemical gases is also valuable. Although the sensing capabilities of our noses are well beyond that achievable by any existing instrument, many applications require non-human odor detecting ability. Compared with a traditional gas chromatograph-mass spectrometer (GC-MS), electronic nose systems have the advantage of being smaller, more portable, and cost economic. Th

Resumen
Thin Film Transistors (TFTs) are widely used in large area electronics because they offer the advantage of low cost fabrication and wide substrate choice. TFTs have been conventionally used for switching applications in large area display arrays. But when it comes to designing a sensor actuator system on a flexible substrate comprising entirely of organic and inorganic TFTs, there are two main challenges – i) Fabrication of complementary TFT devices is difficult ii) TFTs have a drift in their threshold voltage (VT) on application of gate bias. Also currently there are no circuit simulators in

Trabalho de Projeto do Mestrado Integrado em Engenharia Biomédica apresentado à Faculdade de Ciências e Tecnologia<br>Circuitos eletrónicos convencionais são compostos por materiais rígidos e quebradiços. No entanto, orgãos biológicos são fundamentalmente moles (soft). Este desfasamento evidente despertou interesse no campo da electrónica deformável, que se foca no desenvolvimento de materiais e métodos de fabrico para circuitos cujas propriedades mecânicas se assemelham às dos tecidos biológicos. Estes esforços têm sido direcionados para a introdução de novos métodos e técnicas de fabrico de

Resumen
Trend towards downsizing the product size and at the same time to bring more functionality in electronic products, demands electrically interconnecting several miniaturized electronic components with high counts of I\Os (Input/Out put) on smaller and smaller size printed wiring boards [PWB]. These miniature components occupy lower foot print area but require higher routing interconnection densities. However, the conventional multilayer board technologies exhibit limitations when there is need to connect very high I\O components such as ball grid arrays, which require blind and buried interconn

Resumen
The oil and gas industry faces a lack of compact drilling devices capable of performing horizontal drilling maneuvers in depleted or abandoned wells in order to enhance oil recovery. The purpose of this project was to design and develop a smart sensing system that can be later implemented in compact drilling devices used to perform horizontal drilling to enhance oil recovery in wells. A smart sensor is the combination of a sensing element (sensor) and a microprocessor. Hence, a smart sensing system is an arrangement that consists of different sensors, where one or more have smart capabilities.
