Abstract：
Neonatal jaundice refers to the abnormality of bilirubin metabolism for newborns, and wearable transcutaneous bilirubin meters for real-time measuring the bilirubin concentration is an insistent demand for the babies\' parents and doctors. In this paper, a self-powered wearable biosensor in a baby diaper for real-time monitoring neonatal jaundice has been realized by the hydrovoltaic-biosensing coupling effect of ZnO nanoarray. Without external power supply, the system can work independently, and the hydrovoltaic output can be treated as both the power source and biosensing signal. The working mechanism is that the hydrovoltaic output arises from the urine flowing on ZnO nanoarray and the enzymatic reaction on the surface can influence the output. The sensing information can be transmitted through a wireless transmitter, and thus the parents and doctors can treat the neonatal jaundice of babies in time. This work can potentially promote the development of next generation of biosensors and physiological monitoring system, and expand the scope of self-powered technique and smart healthcare area.
摘要：
新生儿黄疸是指新生儿胆红素代谢异常，和可穿戴的经皮胆红素仪实时测量胆红素浓度是一个持续的需求，婴儿\的父母和医生。在本文中,通过ZnO纳米阵列的水-生物传感耦合作用，实现了一种用于婴儿尿布中实时监测新生儿黄疸的自供电可穿戴生物传感器。没有外部电源，该系统可以独立工作，和水电压输出可以被视为电源和生物传感信号。其工作机制是，水电压输出来自在ZnO纳米阵列上流动的尿液，表面的酶促反应会影响输出。感测信息可以通过无线发射器传输，因此，父母和医生可以及时治疗婴儿的新生儿黄疸。这项工作可以潜在地促进下一代生物传感器和生理监测系统的发展，并扩大自供电技术和智能医疗领域的范围。
