Abstract

The present invention discloses a liquid cosmetic ingredient analysis system based on the triboelectric effect. The system includes a microfluidic channel and a self-powered liquid sensor respectively used for manipulating trace liquid samples and analyzing trace element components. A driving component for driving the liquid to flow is connected to the microfluidic channel, and a voltage acquisition component is connected to the self-powered liquid sensor. The self-powered liquid sensor is a multi-layer thin film sensing structure prepared based on the triboelectric effect and the electrostatic induction effect. The multi-layer thin film sensing structure includes a glass substrate (1), a bottom electrode (2), a dielectric layer (3), and a top electrode (4) sequentially arranged from bottom to top. The microfluidic channel (5) is bonded to the upper surface of the top electrode (4). The present invention can determine the components in liquid cosmetics based on different voltage signals generated by the triboelectric effect, can miniaturize the cosmetic detection equipment, and the detection is more simple and fast.
