近场通信 (NFC) 是一种短距离无线通信技术，已成为医疗保健和健康监测领域颇具吸引力的设备。这里报道的工作展示了一种无电池可穿戴传感系统的开发，该系统将温度和汗水传感器嵌入智能纺织品 NFC 天线并由其供电。 NFC天线与封闭体服装无缝集成，传感器数据可以通过NFC阅读器和智能手机轻松获取，从而以便捷、非侵入的方式实现健康状况的实时无线监测。设计并实现了 Dickson 电荷泵电路，以提高电压并确保为汗液传感器提供稳定的电压供应。访问传感器数据的最大读取范围为 6 厘米。温度传感器和汗液传感器的贴身测量精度分别能够达到+/- 0.14摄氏度和+/- 0.2%。所提出的系统可以提供可穿戴式无电池无处不在的无线连接，用于现场护理以及随时的医疗保健和健康监测。
Near field communication (NFC) is a short-range wireless communication technique that has become an attractive device for healthcare and wellbeing monitoring. The work reported here demonstrates the development of a battery free wearable sensing system with temperature and sweat sensors embedded into and powered by a smart textile NFC antenna. The NFC antenna is seamlessly integrated with closed-body garments, and the sensor data can be easily acquired by NFC readers and smart phones in order to achieve real time and wireless monitor of health status in a convenient and nonintrusive way. A Dickson charge pump circuit has been designed and implemented in order to pump up the voltage and ensure a steady voltage supply for the sweat sensor. The maximum read range for accessing sensor data is 6 cm. The on-body measurement accuracy of the temperature sensor and sweat sensor are able to achieve +/- 0.14 degrees C and +/- 0.2%, respectively. The presented system can provide wearable battery-free ubiquitous wireless connectivity for point-of-care and any time healthcare and wellbeing monitoring.
