摘要：Wearable pressure sensors fabricated with sandpaper-molded carbon nanotube-polydimethylsiloxane (CNT-PDMS) electrodes are developed for electronic skins. Compared to the lithography method, widely adopted to prepare pressure sensors based on microstructures, the sandpaper molding method is much more cost-effective and scalable. The microhumps templated from the sandpaper are suggested to amplify the external stimuli during device deformation, leading to an improved sensitivity that is similar to 20 times of the one without microstructures. Moreover, the detectable range of the sandpaper -molded device covers pressures from 5.0 Pa to 50.0 kPa, with a stimuli-response time around 0.19 s and a cycling stability more than 5000 cycles. The sandpaper-molded devices have been explored for external stimuli detection such as pressing, bending and twisting, and human health monitoring including phonation and pulsing.
