美国发明:利用空气为手机充电

　　Mr Tentzeris and his team have used inkjet printers to combine sensors, antennas and energy scavenging capabilities on paper or flexible polymers.

　　Tentzeris教授和他的团队已经运用喷墨打印机的将传感器、天线和能源的搜寻捕捉的能效联合在了纸张或柔软的聚合物之上。

　　So far, the energy captured is minute - measured in microwatts and milliwatts, not megawatts - but is able to gather enough juice to power small sensors and RFID tags.

　　目前为止，该能量捕捉器的功效还十分之效，小到计量单位运用的是毫瓦，而不是兆瓦，不过当其收集到足够的能量时，它能够为小型的传感器和RFID装置补给电量。

　　For example, the researchers last week said they had managed to gather enough energy from a TV station a half-kilometre away to power a small temperature sensor.

　　例如，研究人员们在上周采集了一台电视机周围的电磁能量，并使用其为一台远在半公里之外的温度传感器提供电能、

　　They believe that self-powered, wireless paper-based sensors will soon be widely available at very low cost.

　　研究人员们相信，这种电量自给自足，无限的纸质传感器将在不久的将来被大范围的运用，并且还造价低廉。

　　Researchers hope that when it’s combined with advanced capacitor technology, the device could provide up to 50 milliwatts.

　　研究人员们希望，当这种设备与高级先进的能量捕捉技术联姻之后，设备可以提供的电量可以提升至50毫瓦。
