Title:
METHOD FOR PREPARING THIN FILM PIEZORESISTIVE MATERIAL, THIN FILM PIEZORESISTIVE MATERIAL, ROBOT AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/185212
Kind Code:
A1
Abstract:
Examples of the present application provide a method for preparing a thin film piezoresistive material, a thin film piezoresistive material, a robot and a device, and relate to the technical field of electronic material research. The method comprises: determining the mass ratio of conductive particles to a crosslinked polymer used for preparing a thin film piezoresistive material, the mass ratio ranging from 3: 97 to 20: 80; dispersing the conductive particles and the crosslinked polymer in a solvent according to the mass ratio to obtain a first dispersion; and curing the first dispersion into a thin film piezoresistive material using a liquid dropping method within a temperature range of 25 to 200 degrees centigrade. The technical solution provided by the examples of the present application provides a method for preparing a thin film level piezoresistive material by using a liquid dripping method, the method effectively controls the thickness of the piezoresistive material, thereby preparing a thin film piezoresistive material having a relatively small thickness.
