Created cap against baldness

Created cap against baldness

Engineers developed a baseball cap that stimulates hair growth by exposing the scalp to very weak electrical impulses.

Currently, men usually struggle with baldness with the help of special ineffective lotions, drugs with a lot of side effects or expensive and painful transplant operations.

An alternative is electrical stimulation of the skin, but this procedure is not practical, since it requires daily connection to the device for several hours. However, researchers from The University of Wisconsin at Madison offered a more convenient solution.

They put nano generators inside a regular capfrom several layers of triboelectric materials, with a total thickness of 1 mm, which cover the entire surface of the head and passively transform the mechanical energy of the body’s natural movements into electrical energy. In this case, soft low-frequency charges penetrate deep into the skin, stimulate sleeping follicles and activate hair growth.

The device has passed laboratory tests, and is awaitingapproval for the start of clinical trials, and one of the developers has already tested the effectiveness of a baseball cap on his father. The results showed that such stimulation is at least twice as effective as lotions and popular drugs.

The developers note that the cap will only helpmen who are losing hair now or have recently become bald, because over time, the skin loses its ability to resume hair growth. It will also be useless during sleep due to insufficient movements.

Recently, scientists also developed a miniaturea taster with which you can quickly determine the quality of alcohol and food products, as well as differences between several samples of the same brand with an accuracy of 99%.
