Reference
This article explores the principle of BLE switches, detailing how a micro generator and a BLE RF circuit work together to convert kinetic energy into electrical energy for wireless signal broadcasting.
Principle
The switch consists of a micro generator and a BLE (Bluetooth Low Energy) RF circuit. The micro generator uses electromagnetic induction to convert the kinetic energy from pressing into electrical energy. The RF circuit rectifies and stores this electrical energy and ultimately broadcasts the BLE signal wirelessly.
