摘　　要：Flexible and wearable sensors have broad application prospects in health monitoring and artificial intelligence.Many different single-functional sensing devices have been developed in recent years,such as pressure sensors and temperature sensors.However,it is still a great challenge to design and fabricate tactile sensors with multiple sensing functions.Herein,we propose a simple direct stamping method for the fabrication of multifunctional tactile sensors.It can detect pressure and temperature stimuli signals simultaneously.This pressure/temperature sensor possesses high sensitivity(0.67 kPa^(-1)),large linear range(0.75-5 kPa),and fast response speed(15.6 ms)in pressure sensing.It also has a high temperature sensitivity(1.41%/℃)and great linearity(0.99)for temperature sensing in the range of-30 to 30℃.All these excellent performances indicate that this pressure/temperature sensor has great potential in applications for artificial intelligence and health monitoring.
