The Harvesting of the Energy from the Piezo-Electric Materials Using Sounds

Amar Mallappa Sarwad

Master's thesis

Abstract:

This work deals with research and development of ambient energy harnessing technology from mechanical vibration.To harness mechanical vibration from ambient energy a piezoelectric material is used.To create a vibration, sound is produced from a portable speaker, The sound produced from portable speaker is induced on piezoelectric material ,The frequency of the sound is controlled by laptop by playing a sine wave frequency and it was played at constant volume which was measured by using a microphone, then the series of experiment was conducted on the piezoelectric transducer. To harness the energy from the piezoelectric transducer diode bridge circuit was used, And for measuring the output of the circuit voltmeter was used. The experiment was conducted in five case studies, i.e. by moving the position of a piezoelectric transducer, changing the angle of a piezoelectric transducer, enclosing the setup, changing the area of the enclosure and Connecting two piezoelectric transducers in parallel.
