Investigation and Development of Flexible and Stretchable Vertical Organic Electrochemical Transistors Using Polyimide
Master thesis project
Abstract:
Organic electrochemical transistors (OECT) have recently gained widespread attention in the field of bioelectronics because of their biocompatibility and high transconductance. OECTs provide a powerful solution to detect significantly weak biomedical signals with their high amplification capabilities.
In this study, we are developing a flexible and stretchable vertical OECT. By adopting vertical geometry, there is a decrease in device footprint and a significant increase in transconductance compared to conventional planar OECTs, which is the key to the precise detection of small bio signals. However, to integrate vertical OECT into wearable bioelectronics, flexibility and stretchability of the device are the key factors to consider. Flexibility will allow the device to bend around irregular surfaces (e.g., skin or organs) without losing function. Stretchability will ensure stable device performance under mechanical strain or motion.
By implementing various fabrication and design strategies, this work enhances both mechanical compliance and electrical stability of vertical OECT under deformation.
This research is expected to establish a basis for flexible and stretchable vertical OECT and facilitate successful integration to wearable bioelectronics devices.
