A Batteryless Chronic Wound Monitoring System with NFC

Abstract

This paper proposes a batteryless chronic wound monitoring system with commercial discrete components. To monitor the chronic wound, the proposed system acquires the pH and temperature of the chronic wound. The proposed system adopts 13.56-MHz NFC communications to supply power to an interface circuit and send data to mobile phones. The power consumption of the proposed system is 5.0 mW.
