Zeus represents a new generation of snoring relief. Developed in partnership with King’s College London and Guy’s & St Thomas’ NHS Foundation Trust, this discreet, non-invasive device targets snoring at its source using gentle Transcutaneous Electrical Nerve Stimulation (TENS) technology.

By delivering light stimulation beneath the chin, Zeus helps maintain tongue muscle tone to support an open airway throughout the night, promoting quieter, more restful sleep. Its ergonomic design ensures comfort during all-night wear, while the rechargeable, portable system makes it simple to use at home or while travelling. 

Backed by over 15 years of research and independent clinical trials, Zeus blends proven science with ease of use, helping you — and your partner — wake feeling refreshed and well-rested.

Zeus brings together fifteen years of focused research, engineering, and clinical validation in Transcutaneous Electrical Nerve Stimulation technology. It delivers gentle electrical pulses that stimulate the hypoglossal nerve to improve muscle tone around the airway during sleep. This innovation applies advanced neuromuscular science in a lightweight, silent, and ergonomically designed device. The result is quieter nights and deeper, more restorative rest for you and your partner.

Zeus was born through a 15-year collaboration between engineer Howard Clarke, MBE, and Professor John Moxham of King’s College London. United by a mission to develop a non-invasive, effective solution to snoring, they combined advanced engineering with clinical respiratory research. The result is Zeus—a sleek, UK-developed device that uses transcutaneous electrical nerve stimulation (TENS) to gently activate muscles under the chin, improving airway tone during sleep. Clinically validated and designed for comfort, Zeus represents the next generation of sleep technology—helping you rest better, breathe easier, and wake up refreshed.
