Sony Semiconductor has created a nerve cell sensing array with over 200,000 electrodes spread over a few square millimetres. Aimed at drug research, it allows experiments on nerve cells outside of a human or animal. Made in CMOS, it has 236 880 electrodes in a ~480 x 500 array across 5.5 x 5.9mm. The pixel spacing – 11.22μm square pixels ...

Engineers at University of California Berkley have created at wireless nerve stimulator, claimed to be the smallest of its kind, at 6.5mm2 Called StimDust, it “is the smallest deep-tissue stimulator that we are aware of that’s capable of stimulating almost all of the major therapeutic targets in the peripheral nervous system”, said Berkley researcher Rikky Muller. “This device represents our ...

German researchers have found a way to trick the body into accepting nerve interfaces inside the skull. Such interfaces are used to sense and influence brain waves and, although they are easy to implant, are challenging to keep running properly in living organisms over time, according to the Univerity of Freiburg. “After a while, the immune system tends to treat ...

UK and Singapore scientists have demonstrated the optical fibre equivalent of a nerve synapse, opening the door to all-optical neural networks. The work uses fibres made from metal sulphide chalcogenide light-sensitive glass. “The cognitive functionality of central neurons underlies the adaptable nature and information processing capability of our brains. Now, instead of electrons, light and optical fibres also show promise ...
