High performance, flexible CMOS circuits and sensors toward wearable healthcare applications

Abstract

Macroscale, flexible, and/or stretchable electronics enable to collect a variety of information by attaching it on diverse objects including nonplanar surfaces such as human body. To realize the devices, there are several technical challenges such as (1) low-cost, macroscale sensor network formation, (2) low power and high performance flexible circuits, and (3) other flexible components including battery and wireless communications. In this study, we propose and develop a low power flexible circuit platform using inorganic material-based complementary metal-oxide-semiconductor (CMOS) on a flexible substrate and printed macro-scale, multi-functional sensor networks to address the challenges.
