Falken Technology is a new technology that monitors tire wear from the inside, and best of all, it works by spinning the tire, which means no batteries are needed to replace it. These small sensors not only measure the outside of the tire from the inside, but also increase its individual strength.

Measuring tire wear is generally not a very accurate science, or at least not for most drivers, you just have to look at the huge number of old and unevenly worn tires we see on the roads every day, but what if there was a way to tell if wear is occurring Tires, that's what tire pressure monitoring systems have done.

Falcon has announced that there may soon be a technology that helps understand tire wear. The parent company of the tire brand, Sumitomo, along with Hiroshi Tani of Kansai University in Japan, have developed a way to monitor tire wear from within the tire itself with sensors turned on without the need to a replaceable battery.

To monitor tire wear, the system uses sensors placed inside the tire body that measure the amplitude and frequency of road vibrations that occur as the tire is rolled. This data is then used to determine if the tire is within intended specifications, is old, stiff, over-extended or has been properly built. Uneven, this information can then be passed to the driver.

Sensors that measure wear are also used to generate their own force by rotating a tire. They are called Miniature Energy Harvesters, and there are multiple examples of them in the system.

Understandably, Falken is strict about exactly how it works, but that means you won't need to go in and replace the sensor battery or throw out the tires because the battery has run out.

Having properly inflated tires, their wear parameters, and the life they are meant to last are vital for several reasons, firstly, old or worn tires do not run well on the road, which can lead to a loss of control.

Secondly, uneven tires can affect the vehicle's fuel economy and thus emissions, finally, if the contact patch of the tire can be improved for grip, it is possible to design a lighter and more efficient tire, which will benefit handling and efficiency, all of this is a big win .

It is not clear when we can expect to see this technology on a production tyre, until this time drivers will continue to change their worn tires until the technology becomes available and can be used.
