A standing-wave thermoacoustic engine with gas-liquid coupling oscillation
A thermoacoustic engine usually uses either gas or liquid as the working fluid. However, an analysis based on acoustic-electric analogy indicates that gas-liquid coupling oscillation may lead to lower...

This letter introduces a piezomagnetoelastic device for substantial enhancement of piezoelectric power generation in vibration energy harvesting. Electromechanical equations describing the nonlinear system are given along with theoretical simulations. Experimental performance of the piezomagnetoelastic generator exhibits qualitative agreement with the theory, yielding large-amplitude periodic oscillations for excitations over a frequency range. Comparisons are presented against the conventional case without magnetic buckling and superiority of the piezomagnetoelastic structure as a broadband electric generator is proven. The piezomagnetoelastic generator results in a 200% increase in the open-circuit voltage amplitude (hence promising an 800% increase in the power amplitude). ©2009 American Institute of Physics
