An experimental study of power generation and storage using a flexible piezoelectric device

An experimental study of a small, efficient and flexible piezoelectric power generator is presented herein. Forced vibration experiments were performed and the results show linearity between amplitude of output voltage and maximum vibration velocity. Experiments for storage of the power generated were also performed. These confirmed that the power can be stored in capacitors with the time derivative of the stored energy being independent of the capacitance value.
