A milk protein-based triboelectric nanogenerator and method thereof

Abstract

The invention discloses a milk protein-based frictional nanometer generator and a method thereof. The frictional nanometer generator comprises a scissor fork type supporting structure composed of a plurality of X-shaped structure units; each X-shaped structure unit comprises a first flat plate and a second flat plate which are mutually crossed; conductive ink layers are arranged on the upper surface and the lower surface of each structure unit; a teflon adhesive tape layer covers each first flat plate; each second flat plate is covered with a solid milk thin film layer; and solid milk thin films and teflon adhesive tapes are used as frictional electricity materials. The frictional nanometer generator provided by the invention can provide three working modes for obtaining mechanical energyfrom a human body, and also can detect a motion state, such as walking, running and jumping, of the human body. Moreover, the frictional nanometer generator also can be used for detecting the contentof protein in milk. The research provides a potential, portable, flexible and wearable electronic product, particularly in the fields of micro-energy acquisition, wireless sensing, food quality detection and the like.
