日本综合业务数字地面广播 (ISDB-T) 标准的使用使得智能手机和视频点播能够以更宽的 UHF 频段无线数字电视信号进行永久广播。本文提出了一种独特的能量收集原型，能够从此类广播中获取无线能量，并且能够在距离信号源 6.5 公里的有限工作周期内，通过无线电视信号为工作电压为 3V 的电子设备供电。
Use of Japanese Integrated Services Digital Broadcasting Terrestrial (ISDB-T) standard has resulted in broadcast of perpetually on, wireless digital TV signals over the air at wider bandwidths in UHF bands for smart phones & video-on-demand. This paper presents a unique energy harvesting prototype capable of scavenging wireless power from such broadcasts and well capable of powering on electronics operating at 3V from wireless TV signals for limited duty cycle at distance of 6.5km from source.
