Abstract

This work presents a wireless urine detection system and platform which consists of an electrochemical readout application specific integrated circuit (ASIC) and a biosensor composed of 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) and carbon nanotube (ABTS-CNT) for the detection of urine albumin-to-creatinine ratio (UACR) on cardiovascular diseases healthcare system. The ASIC mainly includes a potentiostat with a current-sensing VCO-based continuous-time delta-sigma modulator (CTDSM) and a hybrid resistor-based digital-to-analog converter (R-DAC), which can be integrated with our developed dual-channel screen-printed carbon electrode (SPCE) for UACR detection. Experimental results have demonstrated the capability of the proposed urine detection system under practical urine tests.
