Paper Abstract

The electrical response of multiple piezoelectric oscillators connected in parallel and endowed with various energy harvesting circuits is investigated here. It is based on the idea of equivalent load impedance of piezoelectric capacitance coupled with harvesting circuits. The main result is the matrix formulation of generalized Ohm's law whose impedance matrix is explicitly expressed in terms of load impedance. It is validated numerically through standard circuit simulations.
