Nanotechnology Now Abstract: The use of graphene nanotubes in fingerstalls made of electrically conductive silicones allowed young scientists from Motorica to make functional prosthetic hands that can interact with touch screens. The cost of cyber prostheses with such functions is 10 to 15 times lower than that of the nearest comparable solutions priced up to $30.000. Graphene nanotubes revolutionize touch screen use for prosthetic hands Luxembourg | Posted on August 3rd, 2021 Today, over 1.5 million handless people live worldwide. According to the World Health Organization, only 1 out of 10 people without hands in the world receives necessary prosthetics, and in developing countries, this figure is down to only 5% of all those in need. A prosthesis should not be an expensive medical product manufactured at a small scale, but should rather become an affordable wearable electronic gadget just like a smart watch or a smart phone. We do more than just restore the functionality of the hand: we expand it, says Vasiliy Khlebnikov, Co-Founder and Chief Development Officer at Motorica, a Russian developer and manufacturer of functional cyber hands.
