Friction nano-sensing unit and self-driven sensing headgear using the same

Abstract

The present application relates to the field of wearable devices, more particularly, to a friction nano-induction unit and a self-driven sensing helmet using the same. The present application is designed based on the principle of contact separation electrification, operates in a single electrode mode, and uses an elastic frame to keep the friction layer and the electrode layer separated under no external force, and to cause deformation of the friction layer and the electrode layer when the substrate two or the substrate one is subjected to an external force, thereby causing contact between the friction layer and the electrode layer, charge transfer, and formation of an induced potential difference. In this way, no external power supply is needed, and the situation of the external force is characterized according to the induced potential difference, which is simple and convenient. The present application solves the problems of single monitoring function of the existing helmet and use limitation caused by the need for additional power supply of the traditional sensor.
