Abstract
In an example, an energy harvesting system includes a support apparatus and a piezoelectric element. The piezoelectric element may be configured as a plate supported at its periphery by the support apparatus to enable a central portion of the piezoelectric element to move along an axis that is orthogonal to a contact surface of the plate. A body having a mass is configured to move in a direction that is substantially parallel to the axis of the plate and apply force to deform the contact surface of the plate, such that electrical energy is generated by the piezoelectric element based on the applied force.
