The Optimization of Analog Front-End for Fully Integrated Wearable Sweat Sensor

The research area of the wearable electrochemical sensors is increasingly growing which are valuable for healthcare and fitness applications owing to their simplicity of operation, low-cost, and compact size. In this work, optimizing of programmable analog front-end for fully integrated wearable sweat sensor is proposed. The proposed system can detect glucose, lactate, sodium, potassium at the same time with low-power consumption which is suitable for continuous real-time sweat sensing system. The average power consumption of analog front-end in the proposed system is less than 2 mW at 3.3 V supply voltage.
