flag MIT's new wireless brain implants can target neurological diseases by traveling through blood and delivering precise stimulation.

flag MIT researchers have created tiny, wireless bioelectronic implants called "circulatronics" that can travel through the bloodstream, self-implant in specific brain regions, and deliver precise electrical stimulation without surgery. flag Coated with immune cells, the devices evade detection, cross the blood-brain barrier intact, and target areas with micron-level accuracy in mouse studies. flag Designed for treating neurological conditions like Alzheimer’s, multiple sclerosis, and brain tumors, the technology uses CMOS-compatible fabrication and could reduce treatment risks and costs. flag A startup, Cahira Technologies, plans to advance the platform toward clinical trials, with future goals including real-time sensing and synthetic neuron functions.
