Injectable Seed-Sized Implant Modulates Nerves Wirelessly for Pain Relief
Researchers have built a seed-sized device that can be injected near a nerve and stimulate it without wires or batteries. It receives power wirelessly from outside the body, and clinicians can adjust its signals in real time. Early tests suggest the approach may one day help treat chronic pain and movement disorders.
Researchers at NYU Abu Dhabi, working with Cleveland Clinic Abu Dhabi, published the work in Science Advances. The team says the device is about the size of a small seed and can be injected through a standard needle, then placed near a chosen nerve. It receives power wirelessly, so no implanted battery or connecting wire is needed.
Clinicians can use ultrasound or CT imaging to guide placement and later verify position. The stimulation is programmable, and lab and preclinical tests showed consistent performance and nerve activation in living organisms. The authors present it as an additional option, not a replacement for medications or surgically implanted devices.
If validated in people, this injectable nerve stimulator could affect patients with chronic pain or movement disorders by offering a less invasive alternative to some surgically implanted devices. Clinicians might adjust stimulation wirelessly in real time, potentially simplifying follow-up care. Healthcare systems may benefit if procedures become easier to deliver, though early preclinical results mean access, cost, and long-term safety remain uncertain. Its societal impact may depend on further trials and regulatory review.
