柔性印刷可穿戴电化学传感器

实现对人体的健康监测和慢性病监测是包括材料科学、信息技术、电子技术、分析化学等科学领域在内的世界前沿课题。通过连续获取温度、压力、应力等物理信号来实现对人体活动情况和心率、血压、脑电图、心电图等实时监测的可穿戴设备已实现商业化,但连续监测人体体液、呼出气中的各类化学物质的可穿戴传感器仍面临许多问题,比如传感器的柔韧性、灵敏度、准确性以及与人体皮肤的贴合性等。针对这些问题,本文以柔性印刷技术为出发点,综述了各类柔性基底在电化学传感器/生物传感器领域的应用,同时对可穿戴传感器的发展方向提出了建议。

Flexible and Printed Wearable Electrochemical Sensor

Monitoring of human health and chronic diseases has become a world-leading subject in the scientific fields including materials science, information technology, electronic technology, and analytical chemistry. Wearable devices for real-time monitoring of human activity and heart rate, blood pressure, EEG, and electrocardiograms by continuously acquiring physical signals such as temperature, pressure, and stress have been commercialized. Wearable chemical sensors still face many problems, such as the flexibility, sensitivity, accuracy of the sensor, and the fit to human skin. Aiming at these problems, this paper takes printing technology as the starting point, summarizes the application of various flexible substrates in the field of electrochemical sensors/biosensors, and proposes the development direction of wearable sensors.
