The wearable tech landscape is on the brink of a seismic shift. Huawei, known for its bold innovations in smartphones and IoT, is now targeting the smartwatch segment with a game-changing feature: an in-display fingerprint sensor.
Leaked patents and insider reports reveal a device that could redefine convenience, security, and design for wearables. Here’s an in-depth exploration of what’s coming—and why it matters.
The Technology: How Huawei’s In-Display Fingerprint Sensor Works
Most smartwatches today use basic PINs, pattern locks, or smartphone-dependent authentication. Huawei’s patent, filed with the China National Intellectual Property Administration (CNIPA), sketches a radically different approach: a full-screen ultrasonic fingerprint scanner.
Key Technical Insights:
- Ultrasonic vs. Optical Sensors: Unlike optical scanners (used in budget phones) that capture 2D fingerprints, ultrasonic sensors (like those in Huawei’s Mate 50 Pro) emit sound waves to create 3D maps of fingerprints. This offers higher accuracy and works with wet or oily fingers—critical for fitness enthusiasts.
- Adaptive Recognition: The sensor reportedly uses AI to learn fingerprint patterns over time, improving unlock speed and reducing false rejections.
- Energy Efficiency: Ultrasonic tech consumes less power than capacitive sensors, a boon for battery life.
Design Advantages:
- No Physical Buttons: Removing side-mounted sensors allows for a symmetrical, edge-to-edge circular display.
- Customizable Activation Zones: Users could assign specific screen areas for quick actions (e.g., payment authentication vs. app locking).
Industry Impact: Challenging Apple, Samsung, and the Status Quo
Huawei’s innovation arrives as the global smartwatch market grows exponentially (projected to hit $96.31 billion by 2030). Here’s how competitors stack up:
- Apple Watch: Relies on iPhone pairing for app approvals and Apple Pay. While accurate, its passcode system feels outdated.
- Samsung Galaxy Watch: Uses a physical rotating bezel and side-button fingerprint scanner—functional but clunky.
- Google’s Wear OS: Depends on “on-body detection,” which lacks robust security for payments.
Huawei’s Edge:
- Standalone Security: Authorize payments, unlock smart home devices, or access medical data directly from the watch—no phone needed.
- HarmonyOS Synergy: Deeper integration with Huawei’s ecosystem (phones, tablets, EVs) could create seamless cross-device experiences. Imagine tapping your watch to unlock a Huawei Mate 60 or start a HarmonyOS-connected car.
Rumored Specs & Features: Beyond the Fingerprint Scanner
While the in-display sensor is the headline, leaks suggest Huawei’s next-gen watch (possibly named Watch Ultimate 2) will pack cutting-edge specs:
- Health Monitoring Suite:
- Medical-Grade ECG: Detects atrial fibrillation with 98% accuracy (CE-certified).
- Non-Invasive Blood Glucose Monitoring: Uses spectral sensors to estimate glucose levels—a first for smartwatches.
- Sleep Apnea Detection: Alerts users to potential breathing disruptions during sleep.
- Durability Upgrades:
- 10ATM Water Resistance: Suitable for deep-sea diving (up to 100 meters).
- Ceramic-Titanium Hybrid Case: Scratch-resistant and 40% lighter than stainless steel.
- Battery & Performance:
- Dual-Chip Architecture: A low-power co-processor handles health tracking, while a high-performance Kirin A2 chip manages apps.
- Solar Charging: A micro-solar panel embedded in the watch face extends battery life by 20% in daylight.
- HarmonyOS 4.0:
- Cross-Device Tasking: Start a workout on your watch, stream it to a Huawei Vision Smart TV, and share stats via a MatePad.
- Third-Party App Support: Expanded partnerships with apps like Spotify, Strava, and AliPay.

Challenges: Can Huawei Deliver?
While the patent paints a futuristic vision, real-world execution faces hurdles:
- Miniaturization: Shrinking ultrasonic sensors to fit a 1.5-inch display without sacrificing accuracy.
- Cost: Ultrasonic tech is expensive—Huawei may price the watch above $699, risking alienation of mid-market buyers.
- Software Optimization: HarmonyOS must rival Wear OS and watchOS in app diversity and smoothness.
Insider Insights:
- Supply chain sources claim Huawei is collaborating with BOE (a leading display manufacturer) to develop ultra-thin, flexible OLED screens tailored for fingerprint integration.
- Early prototypes faced issues with “cold weather lag,” where low temperatures slowed sensor response. Huawei’s engineers reportedly fixed this with a graphene-coated sensor layer.
Market Strategy: Targeting Fitness Pros and Tech Enthusiasts
Huawei isn’t just chasing Apple—it’s carving a niche. The watch’s rumored features suggest a focus on:
- Athletes: Ultra-precise heart rate tracking, VO2 max estimates, and offline maps for hikers.
- Health-Conscious Users: FDA-cleared metrics for blood pressure and arrhythmia detection.
- Luxury Buyers: Limited editions with sapphire glass and bespoke straps.
Regional Focus:
- China: Leveraging home-ground advantage to dominate Asia’s premium wearable market.
- Europe: Partnering with soccer clubs and marathon events for brand visibility.
Future of Wearables: What’s Next?
Huawei’s move could ignite industry-wide trends:
- Biometric Diversity: Future watches may combine fingerprints with vein recognition or heartbeat ID.
- Screen Real Estate: Foldable or stretchable displays could become the norm, with sensors embedded throughout.
- Sustainability: Solar charging and recyclable materials may define next-gen designs.
Final Thoughts: A Bold Step Toward Frictionless Tech
Huawei’s in-display fingerprint sensor isn’t just a feature—it’s a statement. By blending security, aesthetics, and standalone functionality, the company is challenging rivals to rethink wearable design. If successful, this watch could become the iPhone moment for smartwatches, proving that innovation thrives even in a compact form factor.
