1. Product Overview

The V7 is a sleek, ultra-light screen-free smart ring built with a durable titanium alloy shell. As a finger-worn wearable, it weighs only 3 grams, so users can comfortably wear it continuously during work, sleep and light daily activities without the bulk of traditional wrist smartwatches. This ring supports touch gesture control and built-in NFC tap triggers. Furthermore, it uses a PPG optical sensor array paired with a dedicated stress assessment algorithm to collect lifestyle biometric data. The optional portable magnetic charging case extends cumulative usage time significantly. However, this model does not include speaker, microphone or vibration hardware for calls or message alerts, and it omits ECG snapshot and blood pressure trend tracking. All biometric measurements, stress analysis and long-term trend charts are viewed entirely inside the paired mobile wellness application.

Target End Users

Adult male and female consumers seeking a slim, premium low-profile wearable. Their core demands cover continuous heart rate, blood oxygen and skin temperature tracking, stress evaluation, overnight sleep analysis and light fitness logging, plus convenient NFC gesture controls, without notification interruptions or bulky wrist devices.

Target Wholesale Buyers

1. Distributors specializing in premium minimalist health wearables and smart ring product lines
2. Corporate procurement teams sourcing high-end wellness bulk gifts for employee health management programs
3. Private-label brands launching smart ring collections focused on sleep and stress lifestyle monitoring

2. Core Hardware Specifications

2.1 Form Factor & Exterior Finishes

• Wearable type: Finger-worn slim titanium alloy smart ring
• Sizing: Multiple inner diameter physical ring sizes (#7–#12) to fit varied finger circumferences
• Available surface finishes: Black, Silver, Gold, Rose-Gold
• Unit weight: Only 3g for ultra-light all-day wear
• Control method: Touch-sensitive outer shell for simple gesture operation, including remote camera shutter trigger
• Operation note: No on-board screen; all data visualization and biometric analysis take place within the companion mobile app

2.2 Integrated Sensor Hardware

• Optical sensing: PPG optical sensor suite for continuous vital sign sampling
• Temperature sensor: Skin surface temperature detector
• Motion sensing: Built-in accelerometer to capture body movement, sleep status and physical activity
• Extra algorithm: Embedded calculation model to estimate user stress level

2.3 Wireless Connectivity Module

• Radio: Bluetooth 5.2 Low Energy (BLE)
• Extra module: Integrated NFC tap function for convenient quick-trigger operations
• Functional limitations: No onboard speaker or microphone. Therefore, the ring cannot support two-way calling, audio playback or incoming message vibration alerts.
• GPS note: No standalone GPS chip. Activity route tracking depends entirely on GPS signals captured by the paired smartphone.

2.4 Power & Charging Hardware

• Cell type: Miniature 20 mAh lithium polymer battery optimized for low-power BLE sensor operation
• Primary charging method: Custom magnetic contact charging dock for single ring recharge
• Extended power accessory: Optional portable magnetic charging case to extend aggregate usable time
• Runtime performance: Single ring delivers 5–7 typical days of continuous use; the charging case extends total cumulative usage. Actual battery life varies based on sensor sampling frequency and NFC usage volume.
• Safety protection: Multi-layer circuitry prevents overcharging, over-discharging and minor internal short-circuit risks

2.5 Enclosure & 5ATM Waterproof Rating

• Waterproof standard: 5ATM (ISO 22810) dust and water resistance
• Operational limits: Supports hand washing, daily showering and shallow cold-water swimming. On the other hand, it is not suitable for deep diving, hot springs, saunas or high-pressure water jet cleaning. Internal sealing gaskets degrade naturally over extended use and gradually reduce water resistance over time.

2.6 Cross-Device Compatibility

The V7 maintains stable BLE pairing and full tracking features with two mobile operating systems:

• Android 8.0 and newer Android smartphone releases
• iOS 9.0 and subsequent iPhone versions All biometric sync, NFC configuration, stress analysis and historical trend analysis run through a unified multi-language wellness mobile application.

3. Sensor & Wellness Tracking Functions

Mandatory Non-Medical Critical Disclaimer

All heart rate, SpO2, skin temperature and algorithm-estimated stress level metrics produced by this smart ring serve solely for consumer lifestyle wellness reference. This device is not certified medical diagnostic equipment. It cannot be used for disease diagnosis or medical treatment decisions. If users experience persistent physical discomfort or cardiac symptoms, they must consult licensed medical professionals immediately.

3.1 PPG Multi-Parameter Vital & Stress Monitoring Suite

• 24-hour automatic continuous heart rate sampling with manual spot check capability
• Real-time SpO2 blood oxygen measurement for resting and post-activity recovery assessment
• Continuous skin temperature tracking to record shifts in physical condition
• Embedded algorithm to calculate estimated stress levels for long-term lifestyle observation
• Verified lab baseline heart rate measurement accuracy exceeds 97%. Nevertheless, real-world readings may shift based on ring tightness, finger skin condition, body motion artifacts and ambient temperature fluctuations.

3.2 Multi-Stage Overnight Sleep Recording

The ring automatically detects full-night sleep cycles, separating records into light sleep, deep sleep and REM sleep phases. It stores simplified sleep summaries locally and synchronizes full sleep archives to the app’s cloud storage when BLE reconnects to the paired smartphone.

3.3 Activity & Light Sport Logging

• Built-in step counter and multiple light fitness sport profiles for daily activity tracking
• Offline local storage saves workout duration, step count and calorie consumption without constant phone connection
• Once BLE pairing resumes after outdoor activities, all offline fitness records automatically sync to the mobile app cloud.

3.4 Unsupported Specialized Tracking Modules

This minimalist titanium wellness smart ring omits dedicated hardware and firmware for the following functions:

1. Built-in screen for real-time on-ring data viewing
2. Speaker, microphone and vibration motor for calls and message notifications
3. Single-lead ECG snapshot capture hardware
4. Blood pressure trend estimation algorithm
5. Female physiological cycle health tracking reminders and data logging

4. Mobile App Cloud Ecosystem

• Bidirectional BLE data synchronization between the V7 smart ring and multi-language wellness mobile app
• Secure permanent cloud storage for all historical datasets: heart rate, SpO2, skin temperature, stress index logs and sleep & activity records
• Automatically generated weekly and monthly wellness trend reports to help end users observe long-term physical, stress and sleep patterns
• Cloud backup prevents permanent loss of accumulated biometric and activity tracking archives
