Patented Neurotechnology

Quell is an innovative 100% drug-free and non-surgical approach to relieve the symptoms of chronic pain. The device stimulates sensory nerves with safe and precise electrical pulses to trigger a natural pain relief response. Quell is 3X more powerful than typical TENS devices¹ and is a 2019 CES Innovation Award Honoree.

Over 20 Years of Research

The company was started by Dr. Shai Gozani, MD, Ph.D., while conducting research at MIT. NeuroMetrix has spent over 20 years developing technology to help physicians diagnose nerve disorders and, more recently, to address chronic pain.

With over 70 patents awarded since 1996, Quell is the product of this expertise and combines neurostimulation and digital health technologies to relieve chronic pain.
