Flexible Electrochemical Biosensors for Health Monitoring

Flexible electrochemical biosensors play an important role in disease diagnosis and healthcare management. Currently, the applications of flexible electrochemical biosensors are mainly for the detection of biomarkers in various body fluids. Moreover, the flexible sensors can be used as wearable devices for in situ detection and long-term monitoring of target analytes. In this review, the representative electrochemical biosensors including amperometric and potentiometric biosensors prepared on flexible substrates and their major applications are introduced. Then, we focus on transistor-based flexible biosensors that show high sensitivity and low detection limits, which are suitable for multiplexing and high-throughput sensing applications. The current challenges and outlook for the development of flexible biosensors are further discussed.
