Energy Harvesting for a Smart Washer

Smart Component Technologies开发了一种无线智能垫圈，能够测量螺栓连接的夹紧力。该技术旨在监控各种行业(如铁路、核能、石油和天然气)的工厂和阀门安装和日常维护期间和之后螺栓接头的正确夹紧力。目前，该技术依赖于近场无线充电技术和长寿命电池。Smart Component Technologies希望增加一个能量收集设备，以从使用智能紧固件的大多数应用中存在的振动能量中获取能量；这将产生一个真正的即装即用夹紧力监控系统。

Smart Component Technologies has developed a wireless smart washer which is capable of measuring the clamp force of bolted joints. The technology was created to monitor the correct clamp force of bolted joints during and after installation and routine maintenance of plant and valves across a wide variety of industries (e.g. rail, nuclear, oil and gas). At present the technology relies on near field wireless recharging technology and long life batteries. Smart Component Technologies wishes to add an energy harvesting facility to scavenge power from the vibrational energy present in most of the applications where a smart fastener will be used; this will yield a true fit-and-forget clamp-force monitoring system.
