Battery Free Smart Bandage based on NFC RFID Technology

Abstract

We have realised a wireless battery free smart bandage for home and hospital use to monitor skin wound temperature and humidity. The smart bandage is powered wirelessly by Radio Frequency (RF) energy based on NearField Communication (NFC) Radio-Frequency Identification (RFID) technology which also communicates the measured temperature and humidity data. A smart bandage in this form provides simple wound monitoring for the user at home and healthcare professional to monitor groups of patients. Investigations have been undertaken on antenna design, circuit design and bandage system integration. Fabrication is based on photolithography and etching of a copper coated Kapton.
