Researchers at Newcastle University have discovered that a bionic hand, which is similar to Luke Skywalker’s prosthesis and can transmit the information back from the brain. This research is part of a PS1.4 million new project by Engineering and Physical Sciences Research Council. It aims at developing new electronic prosthetic devices to connect with the neural networks in the forearm to enable 2-way communication with the brain. Electrodes for the bionic limb will be wrapped around nerve endings of the arm. This allows the hand to send real-time information about temperature, shear force and pressure back to the brain. The bionic hand Dr. Nazarpour will use to connect with the brain. Image: EPSRC. Dr. Kianoush Nazarpour (Lecturer in Biomedical Engining at Newcastle University) is the study leader. He and his colleagues are working together to create enabling technologies that will give amputees a sense of feedback, and to make a limb almost identical to the real thing. Dr Nazarpour stated that the UK is a leader in prosthetic limb design, but the technological limitations have been a problem. “If we could design a two-way communication system, it would allow amputees to reach for a glass and make eye contact, pick up an apple, or even pick it up without breaking it. This will improve the prosthetics field, enhance prosthesis function, reduce learning time, and make it easier to move the device naturally. This technology can also be used by patients suffering from neurological conditions that reduce sensation. Developing the bionic hands Experts in rehabilitation research across Britain are working to develop fingertip sensors that give prosthetics a real sense of touch. They will detect temperature, shear and pressure. The “virtual hands” will give data about the proprioception of the hand. This is the ability to move the hand and control it without looking directly at the surface. The system then processes the signals into a format that the brain can understand, allowing it to stimulate the nervous system and help the user control their hand. People who are paralysed will be able to function at a higher level with prosthetics that provide feedback. Rory O’Connor is a Senior Lecturer in Rehabilitation Medicine from the University of Leeds. He was a clinical advisor for the project. Current designs look like a socket and plug. The socket is placed over the affected limb. It picks up the signals and allows the patient to use the prosthesis. Unfortunately, many people with disabilities are unable to use their limbs due to injury to their muscles. Nearly 6.5 million British citizens suffer from mobility impairments. 6.3 million are unable to lift or carry heavy objects, and 2.7 million have difficulty with coordination. PSRC award of PS5.3 Million – Additional projects. The EPSRC awarded PS5.3 for funding three other projects: Bionic hand. 2. Project to make a pair smart pants (US English: pants), to aid elderly and disabled people to walk. 3. Biosensors will be used to track how patients with rehabilitation use exercise and equipment. Philip Nelson, Chief Executive at EPSRC said that these research studies would improve the lives of patients, increase independence, and help patients who have mobility or co-ordination problems. With an increasing number of disabilities and the UK’s population ageing, EPSRC investments in healthcare research have a significant national impact.
