CARE2 Smart Ring
A 2.9–4.0 g titanium-alloy ring platform with PPG optical sensing, motion reference and contact-temperature sensing for screen-free wellness programmes.
Key Engineering Highlights
The hardware story in three compact layers: a wearable shell, a sensor chain and a simple charging routine.
Titanium Alloy Shell
Black, silver and rose-gold finishes share the same titanium-alloy outer shell. The full product remains visible in the gallery so surface and inner-sensor geometry can be reviewed without decorative cropping.
Comprehensive Tri-Sensor Array
A reflective PPG channel, 3-axis accelerometer and independent contact-temperature module combine pulse-related, motion and skin-temperature signals for wellness trend presentation.
Magnetic Type-C Charging
The 3.7 V / 15.5 mAh cell charges in the supplied magnetic dock from a 5 V / 1 A Type-C input. No runtime or fast-charging duration is published in the available source.
From Signals to Everyday Insights
Explore how CARE2 connects pulse, oxygen, sleep, activity and personal wellbeing data across the companion app experience.
Pulse & oxygen screens
- •Resting pulse and HRV / recovery presentation
- •Abnormal heart-rate alert interface
- •Single, sleep and 24-hour SpO₂ mode labels
- •Two-second sampling and seven-day sync are source-marketing claims to verify
Sleep & recovery
- •Sleep-stage and duration summaries
- •Overnight pulse, SpO₂ and temperature context
- •Body-recovery / composite-score concepts
- •OSA/AHI risk workflow shown, not clinically validated here
Activity & wellbeing
- •Walking, running, cycling and yoga profiles
- •Marathon, indoor-running and free-training profiles
- •Stress and mood presentation
- •A swimming profile is pictured but does not override the no-swimming water limit
Engagement layer
- •Female-cycle tracking concept
- •Family data-sharing screens
- •AI health-assistant concept
- •Goal, notification and profile controls
CARE2 Companion App Experience
Sleep, pulse, oxygen, activity, sharing and wellbeing screens supplied for the CARE2 programme.
Sleep review interface
The APP will integrate information such as sleep duration, sleep stages, nighttime pulse rate and blood oxygen saturation (SpO₂) into a single assessment for health evaluation.
Everyday profile & goals
Allow users to manage their personal information, goals, notifications, sharing, dark mode and the Apple Health entry in one place.
AI health assistant concept
Provide a conversational artificial intelligence health assistant interface to answer questions related to personal health data.
Family data sharing
Allow authorized family members and friends to view the shared health records through a single page.

Important Wear & Use Notes
Follow these fit, wear and measurement boundaries before positioning CARE2 in a wellness or connected-health programme.
Sizing & Placement Guidance
- 1. We strongly recommend using our physical sizing ring kit prior to bulk production to confirm end-user finger measurements.
- 2. For best optical PPG signal clarity, wear on the index or middle finger where vascular density is highest.
- 3. Ensure the internal sensor bump rests against the fleshy underside (palmar side) of the finger.
- 4. The ring should rotate with gentle resistance over the knuckle without rotating freely during hand motion.
Operational Boundaries & Restrictions
- ✕ Avoid Hot Water & Prolonged Swimming: Thermal shock from saunas, hot showers, or chlorinated pool immersion can degrade adhesive resin seals.
- ✕ No Clinical Diagnostics: Physiological parameters are wellness indicators and not intended to replace formal polysomnography or Holter ECG testing.
- ✕ No Blood Pressure or Glucose Sensing: Ring form factor is dedicated to PPG, motion, and temperature; it does not measure blood pressure or glucose.
Built around your programme
OEM & ODM Customization Scope
Choose the product, packaging and data-path decisions that need to match your market. Each scope is confirmed with your team before production; software interfaces are agreed per project rather than assumed.
Finish & Branding
PVD colours, laser engraving and exterior details can be aligned to your brand system.
Charging & Packaging
Configure branded charging docks, accessory colours and retail-ready packaging.
Sizing & Launch Kits
Use physical sizing kits and branded dummy rings to prepare sampling or distribution campaigns.
Data-Path Review
Review how readings should reach your platform; the interface and integration scope is defined project by project.
