You have 20 muscles in your forearm, the part of your arm between your elbow and your hand. They help you move your arms, hands, and fingers and perform many of the tasks of daily life. You can strain ...

A biohybrid hand which can move objects and do a scissor gesture has been created. The researchers used thin strings of lab-grown muscle tissue bundled into sushilike rolls to give the fingers enough ...

THE hand as a source of clinical information is so obvious that it may be neglected; yet there are no parts of the body more accessible for clinical study. Unique for its abundance of muscles, nerves ...

A groundbreaking development has come from researchers at the University of Tokyo and Waseda University in Japan. They've created a biohybrid hand, a fusion of lab-grown muscle tissue and mechanical ...

Engineers in Germany have built a biologically inspired artificial hand with muscles made from bundles of 'smart' wires. An electric charge is all that's needed to make these wires tense or relax, ...

Engineers have taken a leaf out of nature's book by equipping an artificial hand with muscles made from shape-memory wire. The new technology enables the fabrication of flexible and lightweight robot ...

The main reason is that, although the muscles that control our fingers are in our arms, the touch receptors are in our fingers. This means that our brain can send out the correct signals to our ...

You’ve probably experienced the uncomfortable feeling when your hand muscles tighten or contract uncontrollably and won’t relax no matter what you do. It happens unexpectedly — when you’re writing ...

It may be time to jettison the notion that robots in the future will have grippers or claws for hands. The German robotics company Festo recently unveiled the ExoHand, a sophisticated robotic hand ...
