Anker Introduces Radar‑Based Sleep Speaker to Monitor Rest Without Wearables

Anker has unveiled a new bedside accessory called the Sleep Speaker, which promises to keep tabs on a sleeper's vital signs without the need for a wristband or clip‑on device. The compact speaker sits on a nightstand and uses built‑in sensors to collect data while delivering soothing audio, positioning itself as a hybrid between a white‑noise machine and a health monitor.

The core of the device is a 60 GHz millimeter‑wave radar module. By emitting low‑power radio waves toward the user, the speaker can detect minute chest movements and translate them into continuous readings of heart rate and breathing cadence. Those measurements are then fed into an algorithm that adjusts playback volume, tone, or ambient sounds in real time to encourage a more stable sleep pattern.

Unlike traditional sleep trackers that rely on contact sensors or wearable electronics, Anker’s approach is entirely contact‑free, sidestepping common complaints about discomfort and skin irritation. The speaker also incorporates a subtle visual cue—referred to by the company as “flower power”—that changes color based on the quality of the night's sleep, giving users a quick, glance‑level overview without opening an app.

The launch arrives amid a growing market for smart‑home wellness gadgets, as consumers look for integrated solutions that blend entertainment, health, and convenience. Anker, best known for its charging accessories and audio equipment, is expanding its portfolio into the health‑tech arena, a move that could pressure rivals to explore similar radar‑based monitoring features.

While the technology is promising, experts note that radar‑derived health data raises privacy and regulatory questions. Anker says all information is processed locally on the device and can be synced to a mobile app only with user permission, but the company will need to demonstrate robust data protection as it seeks broader adoption. Future updates may add compatibility with popular health platforms, potentially turning the Sleep Speaker into a hub for nighttime wellness monitoring.
