Transcript of Stark Hand

4th period Mr.wynn Jermaine Young Stark Hand Its a prosthetic hand that's as functional as an electronic model but at a fraction of cost. It was invented by Mark Stark who created it for his friend Dave Vogt who was born without a left hand. The Prosthetic hand attaches to a cable that runs from a shoulder harness worn by an amputee. A lever on the palms open all five fingers at once, and separate cables in each springs at each knuckle allow the fingers to close individually and bend around objects with a secure grip. How It Works When Did it Developed? The Stark Hand In 2004 ,Stark constructed a proof -of concept from hardware-store supplies and gave it to Vogt to try out .Within a hour, Vogt caught a ball left handed for first time in his life.Since then, he has helped the test and improve four more prototypes.Stark designed stronger, compact springs, re-engineered the fingers to a easy to manufacture shapes and set the thumb at new angle to better replicate a real thumb.He also strengthened the joints in hands in hand against side impacts after Vogt broke a prosthetic knuckle when he hit something while swinging around on the dance floor. The hand may have been designed to help a friend, but it also provides another choice among limited prosthetic options.
Hooks can cost only a few hundred dollars, but are limited functionally. Cosmetic prosthetic hands resemble the real thing, but are about as functional as a mannequin's hand.
Electric models offer the best of both worlds, but are often prohibitively expensive. The hand, plus surgery to attach, can cost up to $60,000.
Stark's hand aims to offer increased functionality at a cost closer to hooks.
He spent seven years and roughly $17,000 developing the device. Most of that money was spent in securing a patent The Stark Hand The End!! The Price$? Name: The Stark Hand
