An increasing number of applications of piezoelectric energy harvesting primarily due to its increased energy efficiency and environmental benefits is likely to bolster the demand for the piezoelectric energy harvesting market. Piezoelectricity is the electricity resulting in response to the applied mechanical stress. The electricity accumulates in solid material such as ceramics, crystals, and biological matter such as DNA, proteins, and bone. The piezoelectric effect is a reversible process in which material exhibiting direct piezoelectric effect i.e. charge separation due to stress also exhibits the converse piezoelectric effect i.e. the occurrence of stress and strain when the electric field is applied.

The wide ranging application of piezoelectric includes ultrafine focusing of optical assemblies, to drive an ultrasonic nozzle, microbalances, electronic frequency generation, generation of high voltages, production and detection of sound. The various piezoelectric material used to generate electricity from a mechanical stress includes quartz, polyvinylidene fluoride, aluminum nitride, zinc oxide, lead zirconate titanate, barium titanate, tourmaline, gallium orthophosphate, and berlinite among others.
Piezoelectric energy harvesting is the process which converts mechanical energy to electrical energy, depending upon the amount of stress applied in deforming or compressing the material, the type and amount of deformation of the crystal of the material, and the frequency or speed of vibration or compression to the material.
