Hydrogel-based electrodes for brain implants developed

Hydrogels are physical and chemical polymer networks capable of retaining large quantities of liquid in aqueous conditions without losing their dimensional stability. They are used in a whole host of applications, and in ...

World's smallest optical implantable biodevice

Japanese researchers have described a new implantable device no bigger than the width of a coin that can be used to control brain patterns. The device, reported in AIP Advances, converts infrared light into blue light to ...

Pixels guide the way for the visually impaired

(Phys.org)—Images have been transformed into pixels and projected onto a headset to help the visually impaired in everyday tasks such as navigation, route-planning and object finding.

Implantable medical devices powered by the ear itself

Deep in the inner ear of mammals is a natural battery—a chamber filled with ions that produces an electrical potential to drive neural signals. In today's issue of the journal Nature Biotechnology, a team of researchers ...
