The Next Generation in Neural Prosthetics

The Next Generation in Neural Prosthetics | Differently Abled and Our Glorious Gadgets | Scoop.it

Following up on the success of cochlear and retinal prostheses for people who have lost sensory function, neuroscientists see a limitless horizon for related devices that are able to read electrical and chemical signals from the nervous system to stimulate capability and restore quality of life in persons suffering injury and disease.

In the future, according to researchers, the devices – known as neural prosthetics – will help epileptics, persons with treatment-resistant depression and chronic pain, victims of Alzheimer’s disease, wounded war veterans suffering post-traumatic stress disorder and traumatic brain injury, persons with speech disabilities, and individuals who have sustained spinal cord injury and loss of limbs, among other applications in the research pipeline.

But before neural prosthetics can advance, engineers will be called on to make innovative use of materials to design and fabricate devices that allow sustained electronic functioning in the harsh environment of the human body, without causing tissue infection and other serious adverse conditions. Research efforts have focused on enhancing the performance of various types of materials used in neural prosthetics, in addition to developing interface technologies that enable the micro devices to be safely implanted in human tissue for long periods.

Very interesting wearable - on the inside of the body, - their big issue is having to solve the contradiction of stiff and flexible, turns out it is what is known as Physical Contradiction based on time.  Numerous inventive principles for solving that problem.

This source further discusses the use of brain signals for prosthetics. It also discusses the progression of this technology and its importance.

AR helps amputee experience first pain-free night in 48 years

AR helps amputee experience first pain-free night in 48 years | Differently Abled and Our Glorious Gadgets | Scoop.it

An augmented reality game has helped an amputee suffering from phantom limb pain (PLP) enjoy a good night's sleep for the first time in 48 years.

The system, which works by translating muscular electrical signals picked up by electrodes at the site of the amputation into movements onscreen, was developed by a team at the Chalmers University of Technology in Gothenburg and nearby Sahlgrenska University Hospital. It is an offshoot of work done by Max Ortiz Catalan, who in 2012 developed and trialled a groundbreaking technique for implanting thought-controlled robotic arms and their electrodes directly to the bones and nerves of amputees. He says the idea for the AR phantom pain system came from listening to the struggles of amputee patients at his own clinic. When he decided to trial it, there was one individual whose case was known to be particularly difficult. 

The effects of the trial, have been transformative for that individual.
