Piezoresistive pressure sensor based on flexo photosensitive Resin Plate

In this paper, we propose and fabricate a new piezoresistive pressure sensor by combining micro-structured flexo photosensitive Resin Plate/ Ag and Ag interdigital electrodes through a low-cost process. These plates are made from light-sensitive polymers that are hardened by UV light. The proposed material as a flexible substrate has advantages like Excellent rebound resilience enables high-quality printing with sharp images, high resolution, Cost-effective, etc. our proposed sensor shows sensitivity (18.14 kPa(-1) and 458.2 kPa(-1) in the pressure range of 0 Pa to 1.2 kPa and 1.2-11 kPa), low detection limit (40 Pa), signal response (3.51 s) and recovery response (0.81 s). these characteristics allow the device to work in applications in intelligent robots, human-machine interfaces, and so forth.
