可摄取电子产品已经彻底改变了各种健康状况的护理标准。扩展这些设备的容量和安全性，并降低其供电成本，可以为患者广泛部署长时间监测系统。尽管先前用于体内使用的生物相容性电力收集系统已经证明了来自胃的短（分钟长）电力爆发，但对于长期和整个胃肠道为电子器件供电的潜力知之甚少。在这里，我们报告的设计和操作的能量收集原电池连续体内温度传感和无线通信。该设备提供了平均功率为0.23 μ W mm（-2）的电极面积为平均6.1天的温度测量在胃肠道的猪。这种能量收集电池可以为下一代可摄入电子设备提供能量，使其在胃肠道内长时间工作。
Ingestible electronics have revolutionized the standard of care for a variety of health conditions. Extending the capacity and safety of these devices, and reducing the costs of powering them, could enable broad deployment of prolonged-monitoring systems for patients. Although previous biocompatible power-harvesting systems for in vivo use have demonstrated short (minute-long) bursts of power from the stomach, little is known about the potential for powering electronics in the longer term and throughout the gastrointestinal tract. Here, we report the design and operation of an energy-harvesting galvanic cell for continuous in vivo temperature sensing and wireless communication. The device delivered an average power of 0.23 mu W mm(-2) of electrode area for an average of 6.1 days of temperature measurements in the gastrointestinal tract of pigs. This power-harvesting cell could provide power to the next generation of ingestible electronic devices for prolonged periods of time inside the gastrointestinal tract.
