Wearable Shoe-Mounted Piezoelectric Energy Harvester for a Self-Powered Wireless Communication System

This study covers a self-powered wireless communication system that is powered using piezoelectric energy harvester (PEH) in shoe. The lead-zirconate-titanate (PZT) ceramic of the PEH was coated with UV resin, which (after curing under light) allowed it to withstand periodic pressure. designed simple structure and placed sole durability tested pushing tester its applicability shoes examined. With compression 60 kg, produced 52 ?W at 280 k?. generated by used power transmitter. A step-down converter an under-voltage lockout function gather enough operate transmitter can be operated initially after walking 24 steps. After has been activated, again 8 Because control center receives signals from transmitter, possible check status workers who work outside night or mostly alone, detect emergencies.
