Ultrasound generating microstructures for batteryless remote controls

当代无线遥控器大多使用电池，一些新产品配备了能量收集系统。这两种方法都依赖于电能和电子元件，因而会产生危险废物，因此，人们对不带任何电子元件的机械遥控器感兴趣。应开发两个使用微型哨子作为声音发生器的演示器，以表明这种遥控器可以构建并真正工作：一个用于公寓的电灯开关，其使用适合集成到现有公共汽车系统的编码超声信号，以及发送编码超声信号的哨子的声音测距。

Contemporary wireless remote controls mostly use batteries and some new products are equipped with energy harvesting systems. Both methods are dependent on electric energy and electronic components entailed with hazardous waste.Therefore mechanically actuated remote controls without any electronic components are of interest. Two demonstrators employing micro whistles as sound generators shall be developed showing that such remote controls can be constructed and really work: a light switch for apartments operating with coded ultrasound signals suitable for integration into existing bus systems and sound ranging of whistles sending coded ultrasonic signals.
