Prosthetics breakthrough: Lightest, cheapest and most advanced mechanical hand ever made

This is the most advanced robotic hand ever created - with a design that will lower the price significantly - marking a breakthrough for the field of prosthetics. The so-called Hennes hand, developed by Italian researchers, has only one motor that controls all five fingers, making it lighter, cheaper and more able to adapt to the shape of objects. It weighs about the same as a human hand, and uniquely uses sensors that react to electrical signals from the brain to the muscles, which is much simpler than other'myoelectric prosthetics'. The simplicity will allow the team to price the device about 30 percent cheaper than other models on the market, at 10,000 euros ($11,900). All together, lead researcher Lorenzo De Michieli says there has never been such a natural and accessible option for amputees.
