在本文中，各种环境能量收集技术（太阳能，热，无线和压电）进行了详细的审查和自我维持的无线平台的发展中的适用性进行了讨论。具体而言，远场低功率密度能量收集技术进行了彻底的研究，并已成功地由环境超高频（UHF）数字电视信号（512-566 MHz）供电的嵌入式微处理器传感器平台的基准原型，其中广播天线距离拟议的无线能量收集设备6.3公里。还提出了915 MHz和2.45 GHz的高效双频环境能量采集器和460 MHz的身体应用能量采集器，以验证环境UHF/RF能量采集作为物联网和智能皮肤应用的使能技术的能力。
In this paper, various ambient energy-harvesting technologies (solar, thermal, wireless, and piezoelectric) are reviewed in detail and their applicability in the development of self-sustaining wireless platforms is discussed. Specifically, farfield low-power-density energy-harvesting technology is thoroughly investigated and a benchmarking prototype of an embedded microcontroller-enabled sensor platform has been successfully powered by an ambient ultrahigh-frequency (UHF) digital TV signal (512-566 MHz) where a broadcasting antenna is 6.3 km away from the proposed wireless energy-harvesting device. A high-efficiency dual-band ambient energy harvester at 915 MHz and 2.45 GHz and an energy harvester for on-body application at 460 MHz are also presented to verify the capabilities of ambient UHF/RF energy harvesting as an enabling technology for Internet of Things and smart skins applications.
