AI-Powered Guardian

Acting before
danger even arrives.

True protection doesn't start when you see a notification. When you step into a meeting, squeeze onto the morning subway, or finally sink into deep sleep — DuoLink stays awake. It senses every anomaly through bone-conduction vocal cord vibration, while on-device AI cross-references temperature curves and water intake frequency. The moment danger signals take shape, the first decision is already made: trigger the alarm, activate smart home devices, log the event timeline. All you need is a glance at your phone to know — everything is fine.

AI Bark Recognition Engine

Bone-conduction sensor captures laryngeal vocal cord vibration directly — 0% ambient noise interference. On-device AI classifies 4 bark types in real time — play, alert, whimper, and pain yelp. All inference runs locally, no cloud upload needed: privacy and speed in one.

Breakthrough Silent Alarm

When dangerous signal combinations emerge — abnormal resting temperature + zero water intake for 12 consecutive hours — the App bypasses Do Not Disturb and triggers a critical alert. Early signs of parvovirus, enteritis, and other acute conditions will no longer go unnoticed.

Emotional Wellness Report

A visualized emotional health report every week: anxiety frequency trends, comfort response rates, anomaly event timeline. AI transforms raw data into warm, actionable conclusions — never a cold dashboard.

Radical protection.

DuoLink Woven Core completely abandons the rigid, cold plastic and metal shells of traditional pet hardware. We've invisibly stitched our high-precision hardware core and ultra-thin flexible components into a high-density prep-inspired woven band, co-created by Sarah and our Youth Curator team. Medical-grade liquid silicone (LSR) wraps the skin-facing side, paired with a hidden flex-titanium skeleton — yielding at the micron level with every swallow, stretch, and rest.

No more skin allergies from harsh materials. No more matted fur for long-haired breeds. This is a fashion piece that carries their body heat — and a "second skin" they'll forget they're wearing.

Skin-Side LSR

Medical-grade liquid silicone with flex-titanium skeleton. Micron-level elasticity adapts to neck movement, eliminating friction, allergy, and the rigidpressure of traditional collars.

MIM Frame

Metal injection molded stainless steel with PVD coating. Available in Polar White and Electric Blue — impact-resistant structure with a high-polish luxury finish.

Bone-Conduction Sensor Module

A rice-grain-sized bone-conduction sensing unit embedded on the collar's skin-facing side. Instead of relying on airborne sound waves, it extracts vibration signals directly from the laryngeal vocal cords — tiny in size, yet the physical foundation of the entire emotional perception system.

— Multi-Modal Emotional Auscultation: Hearing the Silent Confessions —

Even miles apart,
feel their heartbeat close.

The bone-conduction microphone captures vocal cord vibration directly, bypassing airborne ambient noise entirely. Combined with infrared skin temperature sensing and a 6-axis laryngeal micro-tremor algorithm, DuoLink builds a multi-modal emotional perception system — it doesn't just "hear" what they're barking, it understands why.

Psychological Stethoscope

Local acoustic algorithms continuously analyze laryngeal vocal cord vibration spectra. When persistent low-frequency whimpering and repetitive pacing — the characteristic pattern of separation anxiety — are identified, the system automatically tags the emotional event and builds a timeline. What you receive isn't a notification that "they barked." It's a contextual behavioral insight you can act on.

Sudden Fear & Hidden Environmental Stress

Thunder outside the window, street roar, unknown ambient chaos... sensitive dogs often fall into panic. By cross-validating infrared skin temperature fluctuations with 6-axis laryngeal micro-tremor (Shaking) algorithms, DuoLink senses their invisible psychological pressure in real time — and prompts you to offer gentle comfort across any distance.

Multi-Modal Cross-Validation

A single sensor is never enough. DuoLink fuses three sensing channels — bone-conduction acoustics, infrared skin temperature fluctuation, and 6-axis laryngeal micro-tremor (Shaking) — to cross-validate every emotional signal. When vocal cord vibration, body temperature curve, and muscle micro-tremors all point toward fear simultaneously, it isn't "guessing." It's confirming.

Technology is silent.
Love is louder.

The market is flooded with cold, clinical pet wearables — they feel more like clunky, rigid "electronic shackles." But to us, pets aren't objects. They are family. And they instinctively hide their pain from us.

DuoLink was born from a little dog named Budou. He was only in this world for 90 days. An aggressive infectious disease masqueraded so well that everyone thought he just "ate too much." When he became lethargic and stopped eating, he couldn't speak — and the cold hardware on the market told us nothing beyond sterile step counts.

That's why we created Woven Core. We stripped away every gimmick and seamlessly stitched medical-grade infrared thermometers, dynamic laryngeal swallowing sensors, and low-power acoustic chips into a soft, waterproof, street-style woven band.

No cold metal. No hard plastic. With its warm, weightless presence, DuoLink speaks the pain they cannot voice:

"For the family members who cannot speak. So that regret never repeats itself."

Limited Seed Beta Recruitment  ·  DUOLINK YOUTH ALLIANCE

Technology is silent.
Let love be louder.

DuoLink Woven Core is never just a smart collar. This is a warm revolution co-created by international school youth curators — we've given a soft woven band the power to read and understand life itself. We don't tell grand narratives of outdoor tracking. We listen to their loneliness, fear, and love in the silence. Our first global batch is limited to just 200 urban seed dogs. We pledge that all pre-sale profits from this beta batch will be fully donated through a reputable charitable foundation to schools in underprivileged mountain regions. With our care for the pups beside us, we illuminate the dreams of children in the mountains far away.
