Clever Artificial Hand Developed

AccUser writes "The BBC is reporting that scientists have developed an ultra-light limb that they claim can mimic the movement in a real hand better than any currently available. Researcher Dr Paul Chappell, a medical physicist who worked on the device, said, 'With this hand you can clutch objects such as a ball, you can move the thumb out to one side and grip objects with the index finger in the way you do when opening a lock with a key, and you can wrap your fingers around an object in what we call the power grip - like the one you use when you hold a hammer or a microphone.'"

Very Promising Future of Prosthetics...

[Nerd Systems]

This hand looks very promising... am sure that it will make many amputees happy as it can more closely resemble the human hand... just curious how much longer till the entire human hand can be duplicated totally... much less other body parts...

I wonder how well someone could type with this hand though, am sure that hunting and pecking would work fine, but since this is controlled by the muscles in the arm, not so sure how efficient typing might be with this hand...

One way to accessorize this hand might be to encase it in a skin toned covering, to more realistically mimic a human hand, and at least to not be so ovbious as this hand is...

Overall this looks like a good step forward in prosthetics... soon people who are unfortunate enough to lose a limb, will be able to lead more normal lives... this is wonderful.

The hand is an assistive technology, true, but the goal should be that it "just works" and does so as unobtrusively as possible, so that it doesn't stick out any more than, say, glasses, contacts, cochlear implants, or hearing aids.

Interesting that you include hearing aids in that list. I've wondered about this for a few years, on and off (I really should get out more), but while glasses have become fashion items, and people with good eyesight will use glasses to help them further (eg sunglasses), you don't see people using hearing aids unless they really have to!

... and what about some sense of fashion for hearing aids? Sure, they are becoming smaller and smaller, but this is just to allow them to be hidden.

I have partial hearing loss and wouldn't even think of using a hearing aid, but anyone with slightly wonky eyes will get themselves some glasses.

How about hearing aids for people with good hearing, for use at the cinema or theatre, that would filter out the dim-wits with their mobile phones and packets of crisps?
How about a device to wear at the Pub which can allow you to filter out the background noise and actually hear, and converse with, your friends?

I reckon there's a long way to go before hearing aids can be mentioned in the same sentence as glasses!

It;s not the hand...

It's not the hand, or motor/servo, or interface that needs improving, it's the Power Source ! Without long-lasting (much better than iPod!) batteries, this technology will go nowhere. I did research in prosthetics back in '75 and won quite a few awards and acclaim for the work, but had the same problem. One solution that was presented back then, but not much work has been done on it since, is a blood-powered fuel cell. It is implanted in the body and derives power from sugar and oxygen. Next best thing would be a pee-powered battery (grin).
