Abstract

Artificial tactile perception emulating slow-(SA) and fast-adapting (FA) mechanoreceptors is crucial for visually impaired individuals as an advanced auxiliary learning electronic system. However, existing sensors, particularly single-mode ones, struggle to simultaneously detect static pressure and high-frequency vibrations due to their inherent response limitations. Herein, for the first time, we report a textile-based bionic tactile sensor (TBTS) that, solely via piezoresistive mechanism, achieves high sensitivity and fast response across an ultrabroad frequency range (5-600 Hz), surpassing human vibrotactile range (
