Miniature motors bring new capabilities to prosthetic limbs

摘要

Miniature DC motors as small as 4mm in diameter are playing an increasingly important role within medical device technology, for example in prosthetic limbs, as Patrick Vega explains Prosthetic limbs are used to replace what is lost to an amputee. These contain DC motors that play a major part in the capabilities of an artificial limb. Prosthetic limbs allow people to gain a sense of feeling of movement again. Imagine something as simple as picking up a glass of water. We require our fingers to wrap around the glass and apply just the right amount of force around the glass to keep it held in your hand. Small DC motors are necessary for these applications.
