Electrodes for prosthetic arm permanently implanted into patient for first time

It took some time, but the age of the cyborg is upon us. For the first time, neuromuscular electrodes that enable a prosthetic arm and hand to be controlled by thought have been permanently implanted into the nerves and muscles of an amputee. The operation was carried out recently by a surgical team led by Dr Rickard Brånemark at Sahlgrenska University Hospital in Goteborg, Sweden. Read More

Scientists use 3D printer and cartilage cells to create artificial ears

When a child is born with the congenital deformity known as microtia, they have an underdeveloped external ear – also known as the pinna. Even though their inner ear may be normal, the lack of the external structure can affect their hearing, plus it looks unusual. Normally, a replacement pinna is made from a foam-like material (or sometimes even cartilage from the rib cage) and implanted under the skin, although these don’t always look particularly natural. Now, scientists from Cornell University have developed a more realistic pinna grown from biological material, using a 3D printer. Read More

Plastic used to replace and regrow bone

Over the past several years, a number of research institutes have been exploring the use of implants made from material with a scaffolding-like structure, as a means of regrowing bone at severe injury sites. Both MIT and Tufts University, for instance, have been working on collagen-based materials. Now, England’s University of Southampton has announced the development of a new type of bone-growing substance, made from plastic. Read More

Million-dollar bionic man built for British TV program

Are the famous lines "Gentlemen, we can rebuild him – we have the technology" from The Six Million Dollar Man coming true? Perhaps not entirely, but a new Channel 4 documentary entitled How to Build a Bionic Man will demonstrate the current state of the art in artificial limbs, organs, and even blood, through the construction of a 6-foot tall android. The documentary is set to air on British televisions come February 7, but you can learn about what went into it after the break.Read More

Quadriplegic woman gets chocolate fix using thought-controlled robotic arm

Earlier this year, a 58 year-old woman who had lost the use of her limbs was successfully able to drink a cup of coffee by herself using a robotic arm controlled by her thoughts via a brain computer interface (BCI). Now, in a separate study, another woman with longstanding quadriplegia has been able to feed herself a chocolate bar using a mind-controlled, human-like robot arm offering what researchers claim is a level of agility and control approaching that of a human limb Read More

Pacemaker-like device being trialled as Alzheimer's treatment

The process of deep brain stimulation involves using a pacemaker-like implanted device to apply controlled mild electrical pulses to specific areas of the brain. In recent studies, it has been used – with some success – to treat conditions such as Parkinson's disease, major depression and Tourette syndrome. Now, in the ADvance Study, researchers at several research centers are exploring its use in restoring memory function to people with Alzheimer’s disease.Read More

Lab-grown brain tissue might lead to bioengineered implants

A team of researchers from MIT and Harvard Medical School have devised a cheap way of artificially growing three-dimensional brain tissues in the lab. Built layer by layer, the tissues can take on just about any shape and closely mimic the cellular composition of the tissue found in the living brain. The advance could allow scientists to get a closer look at how neurons form connections, predict how cells of individual patients will respond to different drugs, and even lead to the creation of bioengineered implants to replace damaged brain tissue.

Mind-controlled permanently-attached prosthetic arm could revolutionize prosthetics

Researchers based at Chalmers University of Technology in Sweden have developed the world’s first thought-controlled, fully implantable robotic arm, which uses an amputee's own nerves and remaining muscles to afford a much more intuitive level of control than previously possible. Initial operations on patients are scheduled to take place during the Northern Hemisphere’s upcoming winter. Read More
