Abstract

This paper presents a double-pendulum-based energy harvesting device to collect energy from random low-frequency human movements. The collected energy is converted into electrical power through electromagnetic induction for self-powered wearable devices. A theoretical model is established to study to nonlinear behaviours of the proposed harvester. It exhibits drastic output responses under low-frequency random excitation similar to human motion. A miniaturized prototype was fabricated and evaluated experimentally under different frequencies and electrical loads. This harvester can achieve a maximum output power of 4.75 mW with a single coil, and the max open-circuit voltage can reach up to 6.24 V, illustrating its promising potential for self-powered sensing from human motion.
