Traditional sleep tracking technology has long operated on the principle that physical attachment equals precision, with devices like rings, watches, and patches designed to be worn close to the body. However, sleep itself is uncontrolled and messy, exposing a fundamental flaw in how most tracking systems are designed. When people fall asleep, their breathing slows, muscles relax, and positions shift—all unintentional changes that affect how wearable devices read data. A smartwatch may rotate, a ring may loosen, or a patch may struggle with motion it wasn't meant to handle, not because these devices are poorly made, but because sleep refuses to stay still.
Most wearable sleep trackers rely on optical sensors, accelerometers, and skin-based measurements, which are sensitive but create noise without stability. Optical sensors depend on consistent light reflection, accelerometers detect movement without distinguishing intention, and skin-contact measurements fluctuate with temperature, pressure, and moisture. Over weeks and months, subtle inconsistencies accumulate, such as changes in strap tightness or sleeping position, causing data to reflect sensor conditions more than sleep behavior. Users often see fluctuating scores and unclear trends, assuming sleep is unpredictable, when the real issue is a lack of consistency in measurement.
In sleep monitoring, accuracy is misunderstood as capturing perfect data points at single moments, but it's actually about capturing the same type of data under the same conditions night after night. Consistency allows meaningful comparisons, and stability turns raw data into insight. This perspective challenges the idea that sensors must always be worn. Instead of asking how to get closer to the body, the team behind SOMNDEEP asked what would happen if they removed the variable that changes the most: physical attachment. They developed the SOMNDEEP Contactless Smart Sleep Monitor, which observes sleep from a fixed position without touching the body at all.
The SOMNDEEP Contactless Smart Sleep Monitor uses millimeter-wave radar technology to detect ultra-fine micro-movements associated with breathing and sleep behavior. Placed near the sleep area at an appropriate sensing distance, the device remains stationary throughout the night, not shifting, loosening, or responding to sweat, skin tone, or temperature changes. Because the environment stays consistent and the sensor doesn't move, the signal remains stable. While wearable devices move with the body, SOMNDEEP observes from outside the system, eliminating many variables that undermine long-term accuracy.
Radar sensing works fundamentally differently than optical or contact-based technologies, detecting subtle physical motion in space rather than relying on light, pressure, or skin conductivity. Even minute movements from breathing are reflected in the radar signal, allowing the device to focus on breathing rhythm and consistency, motion continuity across sleep cycles, and long-term behavioral trends. Radar is not affected by surface-level conditions, avoiding confounding factors that wearables must compensate for, resulting in a cleaner, more repeatable signal that reflects sleep behavior rather than sensor placement.
Non-contact does not mean uncontrolled; the SOMNDEEP Contactless Smart Sleep Monitor operates within a defined sensing range, ensuring accuracy without physical attachment. Once placed correctly, it maintains the same spatial relationship to the sleeper every night, allowing radar signals to remain consistent while avoiding distortions from body-worn sensors. Accuracy in this context comes from repeatable conditions, not proximity alone. For users, this means no device to put on before bed, no discomfort from straps or edges, and no data gaps from forgetting to wear something. Sleep happens naturally, monitoring happens quietly, and stable sensing conditions make changes in data more likely to reflect actual sleep behavior, making long-term trends easier to interpret and trust.
Sleep doesn't follow instructions—people roll over, sprawl, curl up, and change routines without thinking about technology. SOMNDEEP is designed for this reality by staying off the body and maintaining a constant sensing position, working in the background night after night without requiring users to adapt their habits. The most important feature may be what users don't notice. Accuracy in sleep monitoring is often framed as a race toward more sensors and tighter attachment, but sensitivity without stability leads to confusion. SOMNDEEP takes a different view: true accuracy emerges from consistency, repeatability, and minimal interference. By removing physical contact and focusing on stable observation, it offers a clearer picture of sleep as it actually happens, demonstrating that non-contact monitoring, when designed correctly, can deliver reliable, meaningful insights quietly and consistently.
