A Super-Capacitive Pressure Sensor with Ultrahigh Sensitivity and Wide Linear Pressure Sensing Range for Human Bio-Signal Detection and Electronic Skin.

ABSTRACT: Soft super-capacitive sensors offer several advantages, including mechanical flexibility, high sensitivity, and rapid response, primarily due to the use of soft ionic elastomers and the electrical double layer (EDL) sensing mechanism. As for those sensors, achieving a broad linear pressure sensing range remains crucial, particularly when paired with a well-defined microstructure in the electrolyte layer, which enhances sensor repeatability and facilitates quality control. In this study, a novel design strategy is proposed to simultaneously enhance sensitivity and extend the linear sensing range by integrating a hierarchical dome microstructure within the electrolyte layer and incorporating a curvilinear design in the top electrode. Specifically, the optimized sensor shows an ultrahigh sens
