Screws that alert you when they are loose

Much of the vital technology we use in our lives depends on classic and reliable screws. And it is imperative that they tightened to max.

Devices such as bridges, wind turbines, vehicles or machines in general withstand a large load, weight or bolt force and this causes screws loosen over time.

The lesser evil is that performance is degraded, but loose screw Can lead to car breakdowns, accidentsand worse things.

What is usually done in critical equipment is to execute manual periodic checks. But it costs money, labor, takes time, and there is no 100% guarantee that all loose screws will be found.

That’s why the German Institute Fraunhoferknown as the inventor of the MP3 format, developed some screws that warn when they are loose. You can see them on the cover of the news.

These screws are sensor that measures temperature and pressure to which they cuddle for the first time. They can be programmed so that the sensor wirelessly sends reports to operators from time to time or when auger pressure or temperature falls below a certain value, indicates that the screw is being loosened.

In fact, this sensor beautiful movie called DiaForcewhich is where the screw touches the gasket.

These sensor screws are completely self-contained: they have thermogenerator which convert the heat generated by the machine or the pressure on the propeller itself into electricity.

If this system cannot be used, for example on a machine that is under water or operating in cold conditions, they can also be used. several mini solar panels or a battery.

Another advantage screws with sensors is that the head can be placed on any traditional screw to make it smart without changing it.

A great idea that will surely be used in critical industries where it is essential that the screws are fully tightened.
