Wireless, reconfigurable electrochemical measurement platform for wearable applications

Wearable devices have become transformative tools in healthcare and fitness, providing valuable insights into an individual’s health and fitness. Recent advances in electrochemical front-end integrated circuits have expanded the horizons for wearable technology, enabling the incorporation of electrochemical testing in small, power efficient wearables devices. This paper presents a reconfigurable platform tailored for use in a wearable context, offering a versatile transducer interface and electronic configuration suitable for a diverse range of analytes and applications. The platform is based on a custom electrochemical shield with two analog front-end integrated circuits (AD5941), miniaturized IoT board (XIAO ESP32C3) and optional I2C extension boards for physiological measurements. Future endeavors will focus on enhancing accuracy and integration into clothing.
