Abstract

For the first time, we report a reproducible, highly scalable, and highly sensitive broadband 1Hz1kHz vibrated energy harvester with innovated self-alternation magnetic-flux (SAMF) and 3D-coils designs. Record high sensitivity of 2∼6 mV/coil at very wide frequency range of 1Hz 1kHz than previous reports (∼1 mV/coil), record small magnet volume of 132 mm 3, and the very fast transient time of < 0.25 sec are achieved due to innovated SAMF. Meanwhile, we also demonstrated 3D-colis stack-ability for output voltage enhancement. This vibrated energy harvester thus offers high potential for several kinds of applications, such as human motion, automotive etc
