Preparation method of pressure sensor based on composite sponge porous structure

Abstract

The invention provides a high-sensitivity flexible composite sponge pressure sensor. The high-sensitivity flexible composite sponge pressure sensor comprises electrodes and a composite porous structure sponge, wherein silver paste is used for connecting the porous structure sponge and the electrodes so as to increase the electrical conductivity; the electrodes are one of aluminum strips, silver wires and copper sheets; and the electrodes are adhered to the upper surface and the lower surface of the composite porous structure sponge through the silver paste. The invention further provides a preparation method of the flexible pressure sensor. Compared with the prior art, the flexible pressure sensor provided by the invention has the characteristics of low cost, high sensitivity, large measurement range and the like, is prepared by using a flexible material, and can be used for novel wearable equipment. The mechanical sensor is simple in manufacturing work and easy to industrialize, and has extremely high market value and industrialization potential.
