Abstract：In the field of energy harvesting, displacement detecting has been necessary in classical synchronized switch harvesting with inductor (SSHI) which is, however, hard to be applied for magnetoelectric laminated material. In this paper, a novel implement of series-SSHI (S-SSHI) technique is proposed. The electrodes of magnetoelectric laminated material are divided into two pairs, and the assistant pairs are used for voltage detecting and the main pair for energy harvesting. Based on the electrical model of magnetoelectric laminated material with consideration of loss, the triggering signal of S-SSHI is obtained from the voltage detecting on the assistant electrodes instead of displacement detecting device. Experimental results show that, under the same conditions, with the proposed S-SSHI circuit, the maximum harvested energy can increase 60% or more than that of the standard energy harvesting (SEH) circuit.
