The problem of obtaining the optimal size and location of piezoelectric actuator/sensors is addressed. An optimization problem is formulated for a general beam that has arbitrary boundary conditions and may have as many piezoelectric actuators as desired. The proposed optimization criterion is based on a beam modal cost and controllability index. If the(More)
Standing wave thermoacoustic-piezoelectric (TAP) energy harvesters convert thermal energy, such as solar or waste heat energy, directly into electrical energy without the need for any moving components. The input thermal energy generates a steep temperature gradient along a porous medium called "stack." At a critical threshold of the temperature gradient,(More)
