摘要
Flexible piezoresistive sensors hold a great potential with broad application spectrum in human-computer interaction and wearable electronic devices. Inspired by human touch sensation architecture, we report a new type of flexible piezoresistive sensor with ultrawide sensing range and highrobustness by engineering biomimetic structure and carbon black (CB)/MXene/SR/fiber nanocomposites. The facile fabrication processes, piezoresistive sensing mechanism, and performance of the device are comprehensively investigated. The sensor provides a high sensitivity of 2.18 kPa−1, ultrawide linear sensing range of 0.1–1700 kPa, fast response time (∼100 ms), and reliable durability (>5000 cycles). Furthermore, the developed flexible devices have been effectively implemented as electronic skin, demonstrating potential functions in manipulator soft grabbing and human movement monitoring. Such architecture paves the way for great application in the fields of healthcare, human–machine interface, and extremely large pressure monitoring.
