Reading Brainwaves from Inside the Skull
“Researchers at Purdue University have now developed a brain-reading implant that’s incredibly small and that doesn’t need any on-board batteries to power it. Instead, the device, which the researchers say is about the size of a piece of dust, relies on externally delivered electromagnetic waves to power it. It’s conceptually similar to how wireless charging works in some modern smartphones. The implant was produced from a commercially available electronic chip that was modified to include microelectrodes. The device is able to gather electric signals from a number of nerve endings at the same time. It can also be flexible, an important point for implants positioned within tissue resembling gelatin. A tiny antenna works as the energy harvester to power the system.” MORE
