可穿戴式传感器设备技术能够持续监测人体的生物信息，在体育、医疗和医疗领域应用前景广阔。进一步的薄、轻、灵活和低成本是使设备像贴片一样附着在人体组织或衣服上的重要要求。在这里，我们展示了一个灵活的印刷电路系统，由一个基于酶的安培传感器、反馈控制和基于有机薄膜晶体管的放大电路组成。将基于伪cmos逆变器的反馈控制和放大电路通过印刷方法集成在塑料薄膜上。这个简单的系统就像电化学测量的恒电位器一样工作得很好，可以定量实时测量乳酸浓度，灵敏度高达1 V/mM，响应时间短至100秒。
Wearable sensor device technologies, which enable continuous monitoring of biological information from the human body, are promising in the fields of sports, healthcare, and medical applications. Further thinness, light weight, flexibility and low-cost are significant requirements for making the devices attachable onto human tissues or clothes like a patch. Here we demonstrate a flexible and printed circuit system consisting of an enzyme-based amperometric sensor, feedback control and amplification circuits based on organic thin-film transistors. The feedback control and amplification circuits based on pseudo-CMOS inverters were successfuly integrated by printing methods on a plastic film. This simple system worked very well like a potentiostat for electrochemical measurements, and enabled the quantitative and real-time measurement of lactate concentration with high sensitivity of 1 V/mM and a short response time of a hundred seconds.
