Powered Robotic Arm Uses Shape Memory Alloy Instead of Motors
http://cdn.medgadget.com/wp-content/uploads/2015/07/niti**l-prosthesis.pngPowered prosthetic arms typically rely on a ****** of motors, pulleys, and other mechanical contraptions to make them move. These can be heavy and introduce a lot of complexity to the system. **w engineers from*Saarland University in Germany have created a bionic hand that doesn’t have any complex components, relying simply on niti**l wires activated by a current of electricity.
Niti**l, a nickel titanium alloy developed at the Naval Ordnance Laboratory, is a shape memory material that can bounce between two configurations depending on its temperature. By running a current through the metal, the wires can heat up and made to flex. The research team harnessed this property and built the wires into a plastic arm to work as tiny muscles that can tug and pull individual fingers to open and close.
Here’s a Reuters report about the tech**logy
