The German design includes sensors and a transmitter on the head of an industrial screw that warns when it is opened; Otherwise, the screw head will change color when not stretched properly

The connected screws, designed at the Fraunhofer Institute, warn when they are opened;  They have a computer screw head and sensors that determine if it is tight

The evolution of technology and telecommunications, in addition to the miniaturization of the components involved, makes sense to incorporate technology into an element, no matter how small. Example: Connected screws that warn when they are opened They were designed in Germany.

The development comes from the Fraunhofer Cluster of Excellence Cognitive Internet Technologies CCIT and is part of what is known as IoT, or Internet of Things: Communicate with elements of home, factory or city that have not historically had integrated electronics.

Here we are not dealing with home screws, but with much larger elements of industrial use (e.g., windmill, heavy equipment, scaffolding, or attraction); These are screws that are used in situations where the fact that they are slightly loosened is not just an annoyance (clearly loosened plate), but a matter of life and death.

Screws developed by the Fraunhofer Institute (same as the standard set we now know as MP3) A small computer with a transmitter antenna on top, And three sensors in the thread section; Those The sensors work in conjunction with the washer.

When the screw is adjusted to its position, it makes contact with the washer and closes the circle; If for some reason the bolt breaks (vibration, for example) and all three sensors are no longer in full contact with the washing machine, the bolt computer sends a warning. The system is designed to Manage 100000 screws at the same time.

This allows not only to prevent disaster; also Facilitates monitoring of structures and vehicles, As it is not necessary, precisely, to allocate staff to check that all screws are tight; They let themselves know when they are not, something key, if it is, for example, a transmission tower in a remote location that is hard to reach.

Designers also think a Self-sufficient energy systemA solar light or thermoelectric system that uses electricity generated by the temperature difference between one end of a screw that is already used for a non-rechargeable sports watch (Matrix PowerWatch), for example.

Color change screws

They are not the first “intelligent” screws, although they are the first with a wireless connection; Another design, more limited but simple, is that SmartBoltsAn American company that created industrial screws in the back with a small window.

Beyond that window, at the head of the screw, Is an element that changes color depending on how tight the screws are; Thus, at a glance you can tell if the screw is doing its job if it needs additional adjustment. The color change is mechanical; That is, it does not depend on computers, sensors, batteries, or the Internet. The downside, compared to the Fraunhofer, is that you have to be physically next to each screw to check its status. But this is already a breakthrough on traditional screws.
