This paper proposes a batteryless chronic wound monitoring system to accurately diagnose the wound states with lowered cost. To acquire various biomarkers, the proposed system could interface different types of sensor signals (voltage, resistive, and capacitive) using dual-slope integrator circuit technology. A time-to-digital converter is used to digitize the acquired signals. The proposed system adopts 13.56-MHz near-field communication for energy harvesting and sending data. The proposed IC is implemented using the standard TSMC 0.18-mu m CMOS process and occupies an area of 0.5 mm(2). The power consumptions of the proposed interface IC and total system are 1.9 and 3.9 mW, respectively.
