A human locomotion driven hybrid energy harvester for wrist wearable applications

This paper presents a hybrid energy harvester combining an electromagnetic generator (EMG) and a triboelectric nanogenerator (TENG) to scavenge energy from human locomotion. The device is designed for wrist-wearable applications, aiming to provide a sustainable power source for portable electronics by converting the mechanical energy of human motion into electricity.

• Development of a hybrid EMG-TENG energy harvester for wrist-wearable applications.
• Design inspired by human locomotion to efficiently harvest biomechanical energy.
• Demonstrated ability to power a commercial wristwatch.
• Provides a promising solution for self-powered wearable devices.

A prototype of the hybrid energy harvester was fabricated and its performance was tested. The device's ability to generate power from human locomotion was evaluated, and its practical application was demonstrated by using it to power a commercial electronic device.

The fabricated hybrid harvester successfully generated enough power from human motion to drive a commercial wristwatch, demonstrating its potential as a practical power source for wearable electronics and sensors.
