A brain prosthesis designed to help individuals suffering from memory loss has been developed by researchers at USC and Wake Forest Baptist Medical Center.
The prosthesis, which uses a small array of electrodes implanted into the brain, has performed well in laboratory testing in animals and is currently being evaluated in human patients.
An energy harvesting technology that its developers say will be able to turn ambient radio frequency waves into usable electricity to charge low power devices was unveiled in London on Wednesday.
Former British science minister Lord Paul Drayson launched “Freevolt” in a theatre at the Royal Institution, where electromagnetism pioneer Michael Faraday delivered his lectures in the mid-19th century.
Drayson demonstrated the energy created by the signals from mobile phones being used by attendees at the presentation before utilising it to power a loudspeaker in the lecture hall.
The Freevolt technology has a multi-band antenna and rectifier—a type of battery that converts alternating current to direct current—and is “capable of absorbing energy from multiple radio frequency bands,” its developers Drayson Technologies and Imperial College London said in a statement.
