  Researchers at TU/e have developed a very tiny wireless temperature sensor that is powered in a very special way: from the radio waves that are part of the sensor’s wireless network. This means that the sensor needs not even a single wire, nor a battery that would have to be replaced. The arrival of such sensors is an important development on route towards smart buildings, for instance. But the applications are many and various.荷兰埃因霍芬理工大学的研究者开发出了一种微型无线温度传感器,它用一种十分特殊的方式供电——从无线网络发出的无线电波中获得电量。这意味着这个传感器甚至可以不需要电池和电线。这个传感器的到来对智能建筑来说是一个重要的发展方向。而且传感器还会应用在各个领域上。

  The smart buildings of the future will be full of sensors that will respond to the residents’ every need, and will be as sustainable as possible. Like heating and lighting that only switches on when someone is in the room. That’s only possible if these sensors are wireless and need no batteries, otherwise in a large building you would have to change the batteries every day. This is? demonstrated by TU/e researcher Hao Gao who will be awarded his PhD on Monday 7 December for his thesis in which he developed a sensor that measures just 2 square millimeters and weights a mere 1.6 milligrams, equivalent to a grain of sand.

  未来智能建筑将会为了满足屋主的需要而装满传感器,而且传感器要尽可能延长续航时间。当传感器感应到室内有人的时候才会打开灯和暖气设备。为保障你每天不用为传感器更换电池,唯一的可能性是使用不用电池供电的无线传感器。这个可能性已经被埃因霍芬理工大学的研究者高皓(音译)所证明。他在博士课题中开发出了一款2平方毫米表面积、重1.6毫克的传感器,仅相当于一粒沙子大小。
