TL;DR: This work bridges the technological gap between signal transduction, conditioning, processing and wireless transmission in wearable biosensors by merging plastic-based sensors that interface with the skin with silicon integrated circuits consolidated on a flexible circuit board for complex signal processing.
Journal ArticleDOI
Highly deformable liquid-state heterojunction sensors
Hiroki Ota,Kevin Chen,Yongjing Lin,Daisuke Kiriya,Hiroshi Shiraki,Zhibin Yu,Tae-Jun Ha,Ali Javey +7 more
TL;DR: The device architecture and fabrication scheme presented are generic for different sensing liquids, enabling demonstration of sensors responsive to different stimuli, and high sensitivity with excellent mechanical deformability arising from the inherent property of the liquid phase.
Journal ArticleDOI
