Abstract :
This paper reports the design, test and application of a novel low frequency piezoelectric energy harvester. To achieve high output voltage at low frequency, both d31 and d33 modes of polyvinylidene fluoride (PVDF) are utilized in this device. Output voltage of the device are tested under different frequencies and accelerations. Rectifying bridge is used to reverse signals with negative signs and capacitors can be charged to light up a light emitting diode (LED).
