Vibration-to-electric energy conversion using a mechanically-varied capacitor Past research in vibration energy harvesting has focused on the use of variable capacitors, magnets, or piezoelectric materials as the basis of energy tran... Yen,B Chih-Hsun - 《Massachusetts Institute of Technology》 被...
The proposed energy conversion system is analogous to a supercapacitor, whose effective capacitance, internal resistance and energy conversion efficiency are deduced based on the discharging experiments. The work provides a new vibration-to-electric energy conversion mechanism, which may inspire potential ...

In this paper, vibration-to-electric power generator (VEPG) has been designed and direct ac-to-dc power converter topologies are proposed. The permanent magnet VEPG is capable of producing ac voltage, the output is depends upon the amplitude and frequency of vibration source. The generatedAC ...
PROBLEM TO BE SOLVED: To stabilize vibration waves by canceling out the non-uniformity in the positional phase difference of each vibration being generated by the partial non-uniformity of the stiffness of a vibration body by partially changing the stiffness of the vibration body. ;SOLUTION: An ...
Several transduction mechanisms exist for transformation of mechanical energy of ambient vibrations into electric energy. Electromagnetic Transduction seems to be proper mechanism for harsh conditions thanks to its simplicity and robustness. There are many issues though, that need to be worked out yet. ...
A linear MsM energy harvesting device was modeled and optimized for maximum power output. The conversion efficiency, converting from magnetic to electric energy, is approximately modeled from the magnetic field induced by the beam vibration. From the measurement, the open circuit voltage is 1.5 V ...
