DUSQ launches an overnight wearable that responds to sleep disturbances

Sleep wearables have made it easier to understand how well we’re resting, but most of that information comes after the fact. DUSQ is designed to respond to sleep disruptions while they’re actually happening.

The new behind-the-ear wearable monitors the autonomic nervous system and uses a closed-loop system to detect a disruption, deliver gentle vagus nerve and vestibular stimulation, and measure how the body responds.

How it works

DUSQ sits behind the ear using a reusable patch. Its EDA sensor measures changes in skin conductance throughout the night, which the device uses as a window into changes in the autonomic nervous system.

When the system detects a sympathetic nervous system spike, it delivers gentle stimulation to push you back into deep sleep before you fully wake up.

Users can see and interpret the data DUSQ collects overnight in the app.

Rather than relying on a preset stimulation schedule, the system adapts its response based on what it detects and measures the body’s response afterward. Over time, DUSQ says this intervention-and-response data allows the system to become more personalized.

The wearable also works with a bedside charging case that monitors sound, light, and temperature throughout the night. That gives the system additional context around whether something in the sleep environment, like a noise spike or temperature change, coincided with a disruption.

What’s behind the launch

Nervous system regulation has moved further into the wellness mainstream, with growing attention to how well the body responds to stress and returns to a recovered state. DUSQ brings that same focus into sleep.

The company has also begun its own clinical testing. In a registered, sham-controlled trial of 212 participants, scheduled DUSQ stimulation was associated with a 40.1% increase in RMSSD, a measure of heart rate variability, compared with 4.6% in the placebo group.

While the system can’t diagnose or treat sleep disorders, it may help users build physiological resilience to nighttime disturbances over time, so their bodies become less reliant on external support.

Where to get it

DUSQ is available for pre-order at dusq.com. Each order includes the device and charger, a three-month supply of patches, and one year of app access. Orders are expected to begin shipping in October 2026.
