Abstract Multifunctional micro‐force sensing in one device is an urgent need for the higher integration of smaller flexible electronic toward wearable health‐monitoring equipment, intelligent robotics, and efficient human–machine interface. Herein, a novel microchannel‐confined MXene‐based piezoresistive sensor demonstrated to simultaneously achieve multi‐types pressure, sound, acceleration. Benefiting from synergistically confined effect fingerprint‐microstructured channel...
The naturally microstructure-bioinspired piezoresistive sensor for human–machine interaction and human health monitoring represents an attractive opportunity wearable bioelectronics. However, due to the trade-off between sensitivity linear detection range, obtaining sensors with both a wide pressure range high is still great challenge. Herein, we design hierarchically flexible consisting of hierarchical polyaniline/polyvinylidene fluoride nanofiber (HPPNF) film sandwiched two interlocking...
Abstract Nowadays the development of machine vision is oriented toward real-time applications such as autonomous driving. This demands a hardware solution with low latency, high energy efficiency, and good reliability. Here, we demonstrate robust self-powered in-sensor computing paradigm ferroelectric photosensor network (FE-PS-NET). The FE-PS-NET, constituted by photosensors (FE-PSs) tunable photoresponsivities, capable simultaneously capturing processing images. In each FE-PS, photovoltaic...
Abstract Structured piezoresistive membranes are compelling building blocks for wearable bioelectronics. However, the poor structural compressibility of conventional microstructures leads to rapid saturation detection range and low sensitivity devices, limiting their commercial applications. Herein, a bioinspired MXene‐based device is reported, which can effectively boost while broadening response by architecting intermittent villus‐like microstructures. Benefitting from two‐stage...
