This is an ultra-thin wearable device that is implanted directly into the skin

An ultra-thin, super-elastic device that can integrate into the skin will be the future of wearable devices?

According to The Verge, we are approaching the time to eliminate the bulky health sensors because scientists have invented a super-thin wearable device that can write data through the skin. It looks like a tattoo and feels so comfortable that users don't remember wearing it.

Ultra-thin wearable devices can record data through the skin.

Most skins on the skin are electronic devices embedded in a plastic-like substance, which is then integrated into the skin. The problem is that plastics are often hard, hard to move and often cause sweating. According to Nature Nanotechnology, the scientists used a material that dissolves underwater, leaving the electronic part directly on the skin, to comfortably bend and wear. 20 participants wore equipment on their skin for a week without any problems. They are not itchy or irritated and importantly this wearable device is not broken.

There have been many interesting ideas about the remote skin console or turning the skin into a touch screen for a smartwatch. Those are great ideas but health monitoring is a top priority. Most types of tracking devices - from measuring brain signals to measuring heart rates - mean putting electrodes on the skin. This will not be convenient if you need to constantly monitor important signals at home.

These fibers are coated with gold to make them more conductive.

This new system uses a net made of "polyvinyl alcohol" - it is often used in contact lenses and artificial cartilage. First, scientists use electrical energy to make fibers of charged materials. These fibers are coated with gold to make them more conductive. You put the whole substance on your skin - in this case, on your hands and spray on some water. Polyvinyl alcohol will disappear but the golden fibers are still there and it can be used to power LEDs or transmit data to laptops.

Despite its potential, the disadvantage of this sensor is that it may not be durable enough. Therefore, it will take some time for scientists to perfect this technology.
