DUSQ Is a Sleep Regulation Wearable That Responds in Real Time

Detecting Sleep Disruptions as They Happen

Sleep can be disrupted without a person becoming fully conscious of it. According to DUSQ, sleepers may experience 20 to 30 disruptions during a night without remembering them the next morning. The company focuses on these unnoticed events rather than simply measuring their effects after sleep has ended.

DUSQ is a small sleep regulation wearable developed by Ezymind Nexus. Worn behind the ear, it continuously monitors physiological activity associated with sleep disruptions. When the system identifies a change that meets its detection criteria, it is designed to respond automatically within seconds. This separates DUSQ from passive sleep trackers. Instead of only collecting information for later review, the device combines continuous monitoring with an active response during the night.

Reading Nervous System Activity Through the Skin

Detection begins with electrodermal activity (EDA). DUSQ uses an EDA sensor to measure changes in the electrical conductance of the skin. These changes are influenced by sweat-gland activity, which can reflect changes in the autonomic nervous system even while a person remains asleep.

According to DUSQ, the system continuously analyzes these signals to identify what the company describes as autonomic disruptions. Some of these events may affect sleep without causing a complete awakening, making them difficult for sleepers to recognize themselves. The accompanying application also includes placement guidance to help users position the device correctly behind the ear before sleeping.

Responding Through Non-Invasive Nerve Stimulation

Detecting a disruption is only one part of the system. Once DUSQ identifies an event, the wearable is designed to respond using a proprietary combination of non-invasive vagus nerve stimulation and non-invasive vestibular stimulation.

According to the company, stimulation adapts to physiological signals detected throughout the night rather than operating only on a predetermined schedule. After responding, DUSQ continues monitoring for further changes. This makes it a closed-loop system in which sensing and stimulation operate together during sleep.

DUSQ reports that its technology has been developed using more than 50 million data points and four clinical studies. The company reports a 31% increase in deep sleep, a 38% improvement in heart-rate variability, and fewer nighttime awakenings after two weeks. These are company-reported findings and should not be interpreted as guaranteed outcomes for every user.

Designed to Remain in Place Overnight

A sleep wearable must remain practical to wear for several hours. DUSQ is designed to sit flat behind the ear without wires or a prominent pressure point against the pillow. The company states that the device measures approximately seven millimeters thick and weighs around 12 grams.

The wearable attaches using a medical-grade adhesive patch designed for the mastoid area behind the ear. Each patch system is intended for one week and contains seven individual adhesive layers. Users apply a fresh adhesive layer each night while reusing the same base patch throughout the week.

DUSQ also has important limitations. The company explicitly states that the device does not treat sleep apnea and does not replace CPAP therapy. It lists restrictions for people with certain implanted electronic or metallic devices, pregnant users, people with epilepsy or seizure disorders without medical supervision, and anyone under 18. People with active medical implants are advised to consult a physician before using the system.
