An magneto-electric energy converter of rectangular flat-plate has two magnetoelectric composite elements which can be used as masterslave power generator

a novel instantaneous discharging circuit is designed to increase the super capacitance output power.The master magnetoelectric composite elements can harvest electromagnetic energy and storage to super capacitance

and then discharge instantly to increase the output power through the proposed circuit

the slave power gonerator is used to drive management circuit and control discharging circuit work.The experimental results show that when the electric energy accumulates to a certain level

the storage capacitors will discharge and drive the wireless sensor to work

which controlled by the power management circuit.
