As part of DARPA’s Revolutionizing Prosthetics Program, DEKA Research had created The Luke Arm, a hi-tech prosthetic limb with almost natural control mechanisms, that translate signals from a person’s muscles to the bionic arm. But unlike This innovative mind-controlled prosthetic arm, the DEKA “Luke” does not have an electrode neural control system, that is connected directly to nerves. The main signals come from electromyogram (EMG) electrodes, which record electrical activity produced by muscles. A built-in computer analyzes the EMG signals, interprets them and sends a control signal for prosthetic device to make up to 10 specific powered movements.

On Monday, Max Ortiz Catalan, a researcher at the Chalmers University of Technology in Sweden, has announced an innovative mind-controlled prosthetic arm that mimics a lifelike sense of touch. This is what the future of prosthetics looks like and where prosthetic limbs will go. Max has created osseointegrated prosthetic arm with direct structural and functional connection between an artificial titanium implant and living bone, nerves and muscles! An electrode neural control system is connected to nerves, that provides the amputee with sensations and feelings that simulate a real hand’s sense of touch.

25-year-old gamer and amputee James Young lost his left arm and left leg in a rail accident in 2012, after falling under a train in London. Special for James London-based prosthetic sculptor Sophie de Oliveira Barata (the founder of the Alternative Limb Project) and the Japanese game developer Konami have designed a futuristic prosthetic carbon-fiber arm that costs £60,000. The 3D printed hand was built with help from robot hand developers at Open Bionics.

Engineers from Johns Hopkins University have developed mind-controlled prosthetic arm that can move fingers individually and independently of each other. This is really good news for people with disabilities who have lost arms due to disease or injury. The young man on the video below was equipped with a device that use a brain-computer interface to control of his own arm and hand.

E-NABLE makes affordable 3D-printed prosthetic hands for kids

e-NABLE makes free prosthetic hands for kids
e-NABLE is a network of volunteers using 3D printing to give the world a “Helping Hand”

E-NABLE volunteer organization was founded by Jon Schull, researcher at Rochester Institute of Technology (RIT). Jon has connected hundreds of volunteers from around the world to create wonderful cheap prosthetic hands for kids. E-NABLE does not have a central office and does not own any real property. All volunteers are connected and work together through the Internet. They are using 3D printers and open-source technology to print the movable plastic hands. The team of volunteers helps kids and adult with low income to get an affordable prosthetic arm.
