Researchers have introduced a seed‑sized, injectable device that can modulate nerve signals without the need for surgery, batteries, or external wiring. The technology is powered wirelessly from outside the body and has already demonstrated promising early results in managing chronic pain and certain movement disorders. This breakthrough could reshape therapeutic approaches by providing a minimally invasive, long‑lasting solution that sidesteps the complications of traditional neuromodulation implants. Future steps include larger clinical trials to confirm efficacy and safety, alongside development of the external power system needed for everyday patient use. [[1]]
