NYU Abu Dhabi Develops Seed-Sized Injectable Nerve Device for Chronic Pain

2 articles · Updated · The Brighter Side of News · Aug 10

NYU Abu Dhabi and Cleveland Clinic Abu Dhabi built a seed-sized implant that can be injected through a standard needle and stimulate nerves without surgery, wires or an onboard battery.
Wireless power from an external magnetic field drives the device, while a spiral electrode design helps it deliver focused stimulation even when its position near a nerve is not perfectly aligned.
Laboratory and animal tests showed the implant reliably activated nerves and produced controlled muscle movements, with signal strength and timing adjustable in real time.
Researchers said the technology could widen access to treatment for chronic pain, movement disorders, paralysis and other neurological conditions, though long-term stability, anchoring and wearable power systems still need work before broad clinical use.
