Low Voltage Power Supply Using Piezo Electric Effect Under the Guidance of Mr. R.K.DashBy Chinmoy Prasad Roll # EI200117318

Electronics devices are termed as wearable instead of portable Power consumption of the devices limits Size Weight Autonomous lifetime INTRODUCTION

Programmable Microprocessor Bluetooth System MP3 player Personal assistant/organizer Advanced GSM terminal Wearable Devices Functions & Its Power Consumption

Evolution of Power Consumption

SOURCES OF MECHANICAL ENERGY IN THE HUMAN BODY • Breath • Exhalation • Chest expansion • Upper Limbs Motion • Finger motion • Walking

common industrial piezoelectric materials: Polyvinylidene fluoride (PVDF) Lead zirconate titanate (PZT). Piezoelectric materials

Piezoelectric shoe inserts &metal spring with coupled generator

FEASIBILITY OF HUMAN POWERED WERABLE DEVICES

Energy harvesting from human body Low voltage power supply to wearable units by piezoelectric material for computing, communication and audio functions CONCLUSION

THANK YOU
