This is a prosthetic limb like I have never seen

by Mark R

I have to admit that I don’t know what it is like to lose an arm, and need to use a prosthetic one.

I would imagine that the future of prosthesis involves hands that are robotic, but this particular design doesn’t look like Arnold Schwarzenegger’s arm that he revealed in T2.

As you can see, this prosthetic arm doesn’t have any fingers, but the whole thing is like one giant finger with many knuckles. It is, for lack of a better word, a robotic tentacle. If it was silver-colored and had some claws on the end, I would call it a Doctor Octopus tentacle.

Apparently, designer Kaylene Kau wanted to “push the boundaries of current upper-limb prosthetic design”. This prosthetic arm is powered by a small motor within, and makes it so the user can curl around objects.

I believe that we are not at the point where we can create artificial limbs with four workable fingers and one thumb, like the one that Blair Brown has on Fringe. Most Prosthetic devices that I have seen help for gripping objects rather than moves that require a lot of dexterity, like typing. If this version can help out to create a better grip, then more power to the tentacle!

However, I want to make certain that I am factual with what I have reported about prosthesis. So if you have a prosthetic arm or know more about it than I do, feel free to chime in a comment.

Mark –
Touch Bionics, a company based in Scotland, makes the i-Limb Hand with individually articulated, powered fingers and thumb.
Check them out at

My company, Motion Control, Inc. in Salt Lake City, UT makes prosthetic arms, hands that grip, hooks that can replace the hand for more rugged applications and also a wrist rotator to turn the hand or hook. We have also modified our arms to work with the i-Limb hands.
Go to for more information.

This is odd to say the least. I have short arms and I have used a prosthetic arm before. In theory a tentacle would have more strength then a regular hand. It has to do with more surface area, 5 point contact plus palm with a prosthetic compared too say 50 contact points with a tentacle. This will be interesting to watch and see how it progresses, I’m assuming it will have a strong point for some tasks and weak point for other tasks.

Thanks for the info, Roger :) I’m sure our readers will appreciate it

When that is available all we have to do is wait for the first tentacle adult video with this thing in it..
