In article number 2002782, Pukar Maharjan 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.
