Mahmoud Al Ahmad, et al., "Determination of maximum power transfer conditions of bimorph piezoelectric energy harvesters." Journal of Applied Physics 111 (10), 2012, 102812 In this paper, a method to find the maximum power transfer conditions in bimorph piezoelectric-based harvesters is proposed. Explicitly, we derive a closed form expression that relates the load resistance to the mechanical parameters describing the bimorph based on the electromechanical, single degree of freedom, analogy. Further, by taking into account the intrinsic capacitance of the piezoelectric harvester, a more
