Tire warning when exhausted

US researchers are developing a tire that can tell the driver when it is about to exhaust, by attaching a special sensor.

There are also tires that can tell the driver that the pressure in the tire has decreased. However, the new system, developed by Purdue University in Indiana, also allows the tire to detect problems such as tearing, needles, manufacturing defects, loss of balance, wear and tear. ..

Krutz and his colleagues have developed a sensor system that can record the electrical signals characteristic of the material layers on the tire, thus detecting changes that can lead to flat tire or tire wear. Limit as inhomogeneous gas pressure.

A special chip inside the tire will probe the material and quickly send a safety message to the driver.

"The warning takes less than a second , " he said. Krutz said the technology could be applied to tires in construction and mining technology, in mowers and planes.
