Abstract
The invention discloses a three-dimensional carbon-based pressure sensor making method, and relates to the technical field of pressure sensors.The method comprises the steps that foam metal nickel is put into a chemical vapor deposition furnace, methane and hydrogen are introduced for a reaction, and graphene is obtained; foam metal nickel which obtains graphene in the first step is soaked in a mixed aqueous solution of ferric nitrate and hydrochloric acid, foam metal nickel is removed, and foamed graphene is obtained; foamed graphene is washed with water, and drying is conducted; carbon-based fibers are arranged on the top and bottom of foamed graphene respectively to serve as a flexible electrode material; polydimethylsiloxane is poured on foamed graphene and carbon-based fiber flexible electrodes, curing is conducted, and a pressure sensor device is obtained.The pressure sensor has good biocompatibility with a human body and can be closely attached to the skin of the human body to collect physiological signals quantificationally in real time.
