摘要
Abstract
Flexible wearable sensors,as a new generation of artificial intelligence devices,have shown great potential for applications in fields such as human health monitoring,human-computer interaction,and artificial intelligence due to their outstanding performance.However,the rapid development of pressure sensors with high compressibility and sensitivity remains a significant challenge.In this study,we successfully polymerize polypyrrole conductive particles on a polyurethane sponge substrate using a one-step method.A highly compressible sponge is prepared economically and efficiently,and a flexible pressure sensor has been successfully assembled.Due to the three-dimensional porous structure of the polyurethane sponge,it exhibits a high sensitivity response(range of pressure≤1.3 kPa,sensitivity=98.73 kPa-1)and good reproducibility(>2000 compression cycles)under applied pressure.Due to its excellent performance response,the sensors can be placed in different parts of the human body for practical monitoring of physiological and motion signals.In addition,a 5×5 pixel sensing array was prepared for spatial position and pressure analysis,demonstrating the feasibility of sensors in monitoring personal physiological parameters and human-machine interfaces.关键词
