Abstract

We propose a chipless RFID pH sensor which can be easily integrated into a bandage for wound monitoring. The sensor can detect the pH level from 4 to 7 of the wounded area through frequency shift owing to the pH sensitive dielectric parameter of chitosan hydrogel, embedded into the substrate of the sensor. The substrate is composed of fabric material which makes it a strong candidate for non-invasive wound monitoring application. The frequency shift can be wirelessly detected by RFID reader to get the status of the wounded area.
