In order to realize the detection of irregular surface stress

silicon rubber/superconducting carbon black composite material is used as pressure-sensitive material

micro-structured mold is obtained by 3 D printing technology and copies its tiny quadrangular pyramid structure to prepare flexible pressure sensors. In addition

research on manufacture of flexible pressure sensors by screen printing process. Experimental result shows that the sensor can realize the pressure sensing function and the process is simple

the cost is low

the overall size is small

the research provides a solution for large-area

high-density flexible array sensors.
