Researchers Develop Bionic Arm for Patients with Upper Limb Amputation

Concept: Researchers from Cleveland Clinic have developed a bionic arm for patients with upper-limb amputation. It allows the wearer to think, behave, and function like a person without amputation.

Out of the Blue: Dynamic Liquid Crystal Windows

From cutting down on carbon emissions and maximising energy efficiency to enhancing the health and well-being of a buildings’ occupants, the latest ‘smart glass’ and ‘dynamic glazing’ solutions offer unparalleled opportunities. Designed to meet, if not exceed, standards for low and zero-emission buildings, Dynamic Liquid Crystal Windows by Eyrise provide the opportunity to minimise the need for artificial heating and cooling by optimising the use of that generated naturally. In this latest report, the technology’s performance is compared against its closest competitors on colour-rendering, switching speed, and circadian well-being to show where it leads the way. Gaze into the future of glazing by accessing this free whitepaper below.

Nature of Disruption: The bionic arm system developed has three main functions  – the intuitive feeling of opening and closing of the hand, intuitive motor control, and touch and grip kinesthesia. It has three sensory and motor functions in a neural-machine interface unanimously in the prosthetic arm. The neural-machine interface is connected with the wearer’s limb nerves. This helps the patient to send nerve impulses from the brain to the prosthetic as per the wearer’s requirement. It also enables to receive of physical information from the environment to relay it back to the brain through nerves. The bionic arm has bi-directional feedback and control enables the wearer to perform tasks as well as non-disabled people. It is based on target motor reinnervation where patients can move their limbs just by thinking. The reinnervated muscle communicates with a computerized bionic arm to move in the same way. Moreover, it vibrates the kinesthetic sensory receptors in the same muscles to help the wearer feel that their hand and arm are moving.

Outlook: The targeted sensory reinnervation has small robots that activate the receptors while touching the skin. It enables the patient to perceive the sensation of the touch. Researchers from Cleveland Clinic have focused on targeted motor reinnervation also that enables amputees to move the bionic arm how they think. It gives them the liberty to behave naturally. The researchers have found the connection between the different brain behaviors of people with and without upper limb prosthetics.
