Micro-scale Energy Harvesting

Resonant frequency of mass-loaded membranes for vibration energy harvesting applications

Vibration based energy harvesting has been widely investigated to target ambient vibration sources as a means to generate small amounts of electrical energy. While cantilever-based geometries have been pursued frequently in the literature, here membrane-based geometries for the energy harvesting device is considered, with the effects of an added mass and tension on the effective resonant freque...

Multi-frequency piezomagnetoelastic energy harvesting in the monostable mode

The present article investigates effects of the multi-frequency excitation on the output power of a piezomagnetoelastic energy harvester. The piezomagnetoelastic power generator is assumed to operate in the mono-stable mode. A perturbation technique based on the method of multiple scales is employed to develop an analytical solution to nonlinear differential equations governing the system dynam...

Wireless Energy Transfer Using Resonant Inductive Coupling

̈C This paper presents a concept of transmission of electrical energy from a power source to an electrical load without physical conducting medium. It is based on the well known principle of resonant inductive coupling and, in particular, resonant evanescent coupling [1] .This well known physics leads trivially to the result of energy efficient midrange wireless energy-exchange. We establish tha...
