A Wireless Flexible Smart Bandage For Wound Monitoring

A low-cost wireless flexible smart bandage with simple structure for wound monitoring has been developed in this work. The smart bandage was composed of a commercial bandage and a wireless temperature sensor fabricated by facile process on flexible substrate. The smart bandage showed a favorable performance under different mechanical deformations and a maximum coupling distance of 12 mm. The bandage yielded a sensitivity of up to 0.818 MHz/°C in 20–42 °C with a response and recovery time of 24.2 and 28.2 s and with a resolution of 0.5 °C, showing a great promise of the smart bandage as a fast and accurate temperature monitor in wound healing.
