Scientists at NYU Abu Dhabi, in partnership with Cleveland Clinic Abu Dhabi, have developed a miniature injectable device that could transform treatment for chronic pain and movement disorders. Small enough to pass through a standard needle, the seed-sized implant is positioned near a specific nerve and delivers programmable electrical signals to regulate nerve activity — all without surgery, batteries, or wires. Power is supplied wirelessly from outside the body, and stimulation can be adjusted in real time by clinicians or patients.

The device can be located and monitored using standard imaging tools like ultrasound and CT scans, making it easy to guide into place and verify positioning post-injection. Published in Science Advances, the study showed the device could deliver precise, consistent nerve stimulation and successfully activate nerves in living organisms — a key early milestone on the path to clinical use.

Key Takeaways:

• The device is injected rather than surgically implanted, potentially reducing procedure-related risks and recovery time
• Stimulation is fully programmable and adjustable in real time via wireless power
• Compatible with standard imaging (ultrasound, CT) for guided placement and monitoring
• Human efficacy for chronic pain or movement disorders has not yet been established

Why it matters: Existing nerve stimulation therapies often require invasive surgery and complex hardware. If this technology clears future safety and efficacy trials, it could make advanced neuromodulation far more accessible — offering a simpler, safer alternative for millions living with chronic pain or movement disorders.
