最近在材料、机械和设计方面的进步导致了超薄、轻巧的电子设备的发展，这种设备可以与人体皮肤形成共形界面。除了少数例外，这些设备依靠电力来支持传感、无线通信和信号调节。不幸的是，这种能量的大多数来源都是由使用危险材料建造的电池组成的，这些电池的外形因素往往阻碍了与皮肤状或表皮状的电子设备的整合。在这里，我们报告了一种生物兼容的汗液激活电池技术，可以嵌入到柔软的微流体平台中。该电池可以用于包含无线通信和电源管理系统的可拆卸电子模块中，并且能够连续地在皮肤上记录生理信号。为了说明我们方法的实用价值，我们使用人体试验证明，汗液激活的电池可以运行混合微流/微电子系统，同时监测心率、汗液氯化物和汗液。汗液激活的生物兼容电池可以用来为灵活的皮肤上电子系统供电，这些系统监测和无线传输生理信号。
Recent advances in materials, mechanics and design have led to the development of ultrathin, lightweight electronic devices that can conformally interface with human skin. With few exceptions, these devices rely on electrical power to support sensing, wireless communication and signal conditioning. Unfortunately, most sources of such power consist of batteries constructed using hazardous materials, often with form factors that frustrate incorporation into skin-like, or epidermal, electronic devices. Here we report a biocompatible, sweat-activated battery technology that can be embedded within a soft, microfluidic platform. The battery can be used in a detachable electronic module that contains wireless communication and power management systems, and is capable of continuous on-skin recording of physiological signals. To illustrate the practical utility of our approach, we show using human trials that the sweat-activated batteries can operate hybrid microfluidic/microelectronic systems that simultaneously monitor heart rate, sweat chloride and sweat pH.Sweat-activated, biocompatible batteries can be used to power flexible on-skin electronic systems that monitor and wirelessly transmit physiological signals.
