Hybrid Energy Harvesters: A Fully Functional Universal Self‐Chargeable Power Module for Portable/Wearable Electronics and Self‐Powered IoT Applications (Adv. Energy Mater. 48/2020)

In article number 2002782, Jae Y. Park and co-workers develop a universal self-chargeable power module to efficiently harvest random low frequency and low acceleration vibration energy from human motion, water-wave motion, and automobile vibration. By implementing multiple spring mechanical coupling, a flexible flux-concentrator, and electrospun nanofibers, the power module delivers a high DC output power of 34.11 mW which can easily power wearable/portable electronics and sensors.
