Intelligent child safety lock system based on triboelectric nanogenerator array trajectory recognition

Abstract

This invention discloses an intelligent child safety lock system based on the trajectory recognition of a triboelectric nanogenerator array (TENG). The system collects user-input spatial trajectory information by deploying a flexible TENG array on the surface of household appliances. The TENG utilizes the coupling effect of triboelectric charging and electrostatic induction to convert triboelectric energy into electrical energy, which is then supplied to subsequent circuits. Simultaneously, the trajectory information is converted into an electrical signal that matches the trajectory. The information processing and acquisition unit modulates this signal and transmits it to the central processing unit for matching with the electrical signal of a preset unlocking trajectory. The central processing unit outputs control commands, which are then executed and fed back by the execution feedback unit. This system effectively resolves the energy efficiency conflict, significantly enhances safety, and possesses excellent environmental adaptability.
