Wearable, highly sensitive, and low-cost pressure sensors are desirable in the field of electronic skin. Here we report a solution-processed fabrication strategy to construct a highly sensitive, flexible pressure sensor by laminating silver nanowire (AgNW) patterns/Polydimethylsiloxane (PDMS) layer and poly(3, 4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS)/PDMS layer with micro-structure. The AgNWs with interdigitated pattern, as an electrode, was fabricated by a wetting/dewetting process. The micro-structure of the PEDOT: PSS/PDMS layer was replicated from a sandpaper. The sensors are able to detect the pressure as low as 100 Pa with large pressure region (up to 140 kPa) and fast response time (<40 ms).
