一种无需电池的新型传感器近日由德国慕尼黑的西门子研究人员设计成功。与传统传感器不同,这种全新传感器可在既定情况发生变化的情况下自动生成报告,并可从报告的事件本身获取所需能量。这种传感器可在家里使用,即利用一台PC机对不同传感器的报告进行监控。在这种情况下,其应用可包括:门铃、紧急呼叫、远程控制、报警、照明灯开关;对门、窗、窗帘、保险箱、煤气表和水表的监控;人体和动物活动、室外 A new battery-less sensor was recently designed by Siemens researchers in Munich, Germany. Unlike traditional sensors, this new sensor automatically generates reports as the set conditions change and retrieves the energy required from the reported events themselves. This sensor can be used at home, using a single PC to monitor different sensors. Applications in this context may include: doorbell, emergency call, remote control, alarm, light switch; monitoring of doors, windows, curtains, safes, gas and water meters; human and animal activities, outdoor
