A piezoelectric generator is a device that converts mechanical energy, such as vibrations or pressure changes, into electrical energy using the piezoelectric effect. This effect occurs in certain materials, like certain types of crystals or ceramics, where applying mechanical stress to the material leads to the generation of an electric charge across its surface. This phenomenon is reversible, meaning that the material can also deform in response to an applied electrical voltage.
In remote sensing applications for scientific exploration, a piezoelectric generator can be used to capture and convert ambient mechanical
