This project develops an innovative shoe with an integrated piezoelectric device to harness energy from walking. The generated kinetic energy is converted into electrical energy, stored in a rechargeable battery, and used to charge mobile phones. The system includes a DHT11 sensor for battery temperature monitoring and a voltage sensor for tracking voltage levels, both interfaced with a Node MCU microcontroller. Data is transmitted to a mobile app using the Blynk platform for real- time monitoring and alerts. This smart shoe offers an eco- friendly, portable power solution, combining piezoelectric technology with IoT (Internet of Things) for sustainable personal energy management.
