Flexible electronics have attracted great attention over the last few decades, and novel application have been developed in the fields of displays, sensors, electronic textiles, electronic skins, as well as imperceptible and transient implants. To obtain flexible electronics with improved performance, two different strategies have been utilized to improve the novelty of electronic devices in terms of electrical and mechanical properties: (1) structural engineering of the electronics; (2) developing electronics with new materials. Thin film transistors (TFTs) are one of the most common and important building blocks in most electronic systems. They are used in a wide range of signal manipulation and computation circuits, as well as matrix-controlling elements in displays. In this dissertation, developing flexible TFTs with novel electrical and mechanical properties will be discussed. In Chapter 2, flexible TFTs on a cellulose paper/ion gel composite are discussed. The cellulose paper/ion gel composite, which serves as both the dielectric and substrate of TFTs, is a low-cost material and enables the TFTs to operate at low voltages due to its high specific capacitance. Furthermore, the cellulose paper/ion gel composite has excellent mechanical flexibility for flexible electronics. In Chapter 3, the development of intrinsically stretchable TFTs, which can undergo large and reversible deformation, is discussed. The solution processed P3HT/MWNTs/ PDMS composite was used as the active layer of the intrinsically stretchable TFTs. In the composite, the MWNTs provide fast conducting channels for carrier transport to significantly improve the field effect mobility. On the other hand, the PDMS enhances the stretchability of the composite active layer, and the cyclical stretch-release test shows the TFTs can remain functional without an apparent mobility decrease.In Chapter 4, flexible degradable devices are demonstrated. Devices that are traditionally designed on passive substrates, which only serve as supports, are instead fabricated on active substrates that can dissolve. Novel moisture-triggered physically transient electronics were designed, which exempt the needs of resorption solutions and can completely disappear within well-controlled time frames.
