In actual detection of pressure signal

magnitude of the applied pressure value and distribution of the pressure are all important test data.Nano-sized acetylene blacks and silver-plated glass microspheres are used as conductive fillers

and 107 silicone rubber is used as base material to prepare pressure sensitive silicone rubber. A flexible electrode array is prepared by screen printing process. Finally

the pressure sensitive silicone rubber and the flexible electrode are packaged together to prepare a sandwich structured 10×10 array pressure sensor.The results show that the prepared flexible sensor has small size

high density and low cost

and can realize the detection of the size and distribution of pressure.
