Two Ryerson University undergraduate biomedical engineering students are changing the world of medical prosthetics with a newly developed prosthetic arm that is controlled by brain signals. The Artificial Muscle-Operated (AMO) Arm not only enables amputees more range of movement as compared to other prosthetic arms but it allows amputees to avoid invasive surgeries and could potentially save hundreds of thousands of dollars. The AMO Arm is controlled by the user's brain signals and is powered by 'artificial muscles' - simple pneumatic pumps and valves - to create movements. In contrast, traditional prosthetic limbs – which typically offer more limited movements – rely on intricate and expensive electrical and mechanical components.
