Hand

While a number of groups are developing thought-controlled prosthetic hands, most of the devices require fiddly electrodes to be implanted in the amputee's body. Such is not the case with a new system, however, which works with implanted magnets.

Having an extra thumb on one hand may boost your manual dexterity, but wouldn't it be hard to learn to use? Not according to a new study, which found that the majority of a wide variety of people got the hang of the thing in just one minute.

A robotics company likely most famous for a demo of its dexterous robot hand at Amazon re:MARS with Jeff Bezos has now unveiled a new robust model designed for machine learning research, which was developed in collaboration with Google's DeepMind.

An experimental new wearable could allow people such as stroke victims to communicate via subtle hand movements. The device takes the form of a relatively thin patch that is temporarily adhered to the skin on the back of the wrist.

There are already a number of experimental prosthetic hands that provide users with the tactile sensation of touching an object. The MiniTouch system takes things further, as it allows users to sense the temperature of items that they're touching.

Currently, almost all powered prosthetic hands utilize electrodes that detect the user's muscle impulses and convert them into hand movements. A new system which is in development, however, should reportedly work better by utilizing ultrasound.

Hand edema, which is a swelling of the fingers due to the accumulation of fluid, is typically treated via a hand massage performed by a therapist. A new finger-massaging glove, however, may offer a less costly and more accessible alternative.

If a robot is going to be grasping delicate objects, then that bot had better know what those objects are, so it can treat them accordingly. A new robotic hand allows it to do so, by sensing the shape of the object along the length of its digits.

While technology is making strides in absorbing our eyes and ears in virtual worlds, it’s harder to engage senses like touch. Engineers have now developed WeTac, a thin, wearable electronic "skin" that provides tactile feedback to users in VR and AR.

Clone Robotics is going to impressive lengths to make sure its "intelligent androids" will have some of the most human-like hands in the business, and watching the way their hydraulic "muscles" move under a transparent skin is absolutely hypnotic.

When someone has been left paralyzed by a stroke or brain injury, much of their recovery involves physically guiding the affected limb though the lost motion, so their brain can relearn it. A new exoskeleton does exactly that for the hand.

It goes without saying that surgeons require a very delicate, precise touch. A new set of surgical training gloves were designed with that fact in mind, as they monitor their wearer's hand movements, and provide feedback on their technique.
