'Insect tape'

At first, you may think this is a new method of catching insects, but not so, that is the name scientists put on a new type of adhesive tape with superior features, which have a structure simulated by structure. Creating feet of insects.

This adhesive tape has 3 times stronger adhesion than regular adhesive tape. It is not afraid of dirt surfaces, washed with soapy water and reused thousands of times.

As its name suggests, " insect adhesive tape " is jointly researched and manufactured by German and American scientists based on the preeminent structure that the Creator gave to the feet of insects.

Although from the 19th century humans began to pay attention to the ability of insects to move on walls and ceilings. But until recently, when science developed, it was known that insect legs had two types of adhesion structure that were adhered to smooth surfaces (like grasshoppers) and adhered to the surface of feathers (like cockroaches). ).

" Insect tape " belongs to the second type. Thanks to the thick coat, it makes the most of the contact area. In addition, soft hairs can crept through dust particles and self-elastic, elastic to match the properties of the exposed surface. So this tape is still highly effective even when it comes to contact with objects that have an uneven surface, cracked or dusty.

On a flat glass surface, " insecticidal tape " has just been created with a adhesion level of about 60% of the gecko's adhesion level. But that is enough to help a spider-shaped robot weighs 120g, is remotely controlled, has legs attached to " insect tape ", crawling up the vertical glass wall easily.

In addition to making specialized robots, " insect tape " can now be used to lift optical lenses and CDs, to protect or attach other objects to easy glass surfaces. scratched. Scientists will continue to improve the adhesion as well as the shape of this product so that it is available for other special applications in the future.
