Abstract
Flexible sensors are very important for a broad range of applications including wearable health care systems, human-machine interfacing devices, and artificial intelligence. Due to their unique capability, flexible sensors have attracted increasing attention. Here we report flexible capacitive micro-structured sensors based on a sandwich structure by laminating the silver nanowires (AgNWs) composite and the polydimethylsiloxane (PDMS) film together with PDMS as a dielectric layer. To better understand the performance of the sensors, we compare the flexible pressure sensors with micro-structured electrodes to that without one. The reported sensors with micro-structured electrodes demonstrate better performance with higher sensitivity (1.1 kPa−1), lower detection (1Pa), a faster response time (<1s) and better stability than that of the sensors without microstructures.
