Abstract

Flexible tactile-sensing devices are crucial for enhancing precision in wearable interaction electronics. However, traditional array-based sensing units encounter challenges in high environment robustness and spatial resolution. To address this limitation, we propose an array-free tactile-sensing E-textile that attains superior spatial resolution by exploiting non-faradaic junction effect between the E-textile and the human body. Upon finger contact, ions in the dermis redistribute directionally at the interface, creating a purely capacitive coupled nonfaradaic junction behavior that rapidly generates tactile-sensing signals (
