With the rapid emergence of flexible electronics, pressure sensors are importance in various fields. In this study, a dopamine-modified melamine sponge (MS) was used to prepare honeycomb structure carbon black (CB)/MXene-silicone rubber (SR)@MS sensor (CMSM) through layer-by-layer self-assembly technology. Using SR as binder construct not only improves mechanical properties but also provides more attachment sites for CB/MXene, enhancing stability conductive network. The CMSM exhibits high sensitivity (7.44 kPa-1), wide detection range (0-240 kPa), short response/recovery times (150 ms/180 ms), and excellent stability. addition, smart insole has been developed based on 6-unit array, achieving plantar detection. By combination ResNet-50 neural network algorithm with data under different postures, recognition 16 types human motion postures achieved, an accuracy rate 90.63%. This study proposes performance sensing capabilities, providing new ideas references design wearable devices.

Abstract Most flexible ionic tactile sensors can hardly be used in deep sea due to their poor antiswelling and anticompression properties under high hydrostatic pressure. To achieve pressure position sensing pressure, a self‐powered underwater sensor made of porous thermoplastic polyurethane (TPU) film is presented this paper.
