A stretchy see-through gel that conducts electricity could make replacement muscles or artificial skin.

Second Sight Medical Products has developed a medical device, Argus II retinal prosthesis system, that gives blind people a form of sight.

The device includes a miniature camera that fits into the patient’s glasses, which converts video images into a series of small electrical pulses. The impulses are transmitted wirelessly to electrodes implanted on the surface of the retina. These stimulate the remaining cells in the retina to create patterns of light in the brain, and the brain learns to interpret these patterns.

This has been developed for patients who have lost their sight through retinitis pigmentosa, an inherited eye disease that damages the retina at the back of the eye.

Scientists are working on invisibility cloaks for light, sound, water and even earthquakes. The light-bending fabric (see the abstract) made objects invisible to the human eye.

By soaking a cheap T shirt in fluoride (don’t try this at home), drying it and baking it, researchers have been able to create a fabric that can be charged and discharged, and could one day be used to charge mobile devices like phones.

See the original research in the Advanced Materials journal.

Researchers have invented a robot jellyfish, fueled by hydrogen, that could one day be used for ocean rescues. The vehicle, called Robojelly, uses shape memory alloys – metals that ‘remember’ their shape.
