Graphene and MXene-based Sponge Pressure Sensor Array for Rectal Model Pressure Detection

Flexible sensor is one of the prevalent directions in the sensor field, and the sensing material and structure are the main aspects that affect the performance of the sensor. This paper studies a flexible pressure sensor based on Graphene/MXene-PDMS @ sponge. Using the porous skeleton structure of sponge and the high conductivity and synergy of Graphene and MXene to prepare a set of high sensitivity (0.053kPa(-1)), high stability (2000 cycles loading), and variability (0-35 kPa detection limit), all-in-one sensor. In the rectal model pressure detection experiment, the sensor array can effectively detect static pressure, systolic pressure, and corresponding abnormal pressure detection. Experimental results show that the sensor has a good prospect in detecting rectal pressure.
