Detailed engineering and commercial answers to simplify your supply chain evaluation.
Grade 5 titanium alloy (Ti-6Al-4V) exhibits a tensile strength exceeding 880 MPa, nearly double that of 316L stainless steel, while weighing 45% less. Furthermore, titanium exhibits superior biological inertness (preventing allergic contact dermatitis) and is non-ferromagnetic, ensuring zero interference with high-frequency wireless charging coils and RF transceivers.
A continuous 360-degree metallic band acts as a Faraday cage, severely dampening Bluetooth signals. High-tier manufacturers solve this by utilizing an inner ring lining made of medical-grade non-conductive epoxy resin or zirconia ceramic, integrating a micro-dielectric window or an inverted-F trace antenna (IFA) along the resin aperture to radiate freely outward.
At Shenzhen Tucks Technology, standard white-label orders start at an accessible minimum order quantity of 200 units per model. Functional engineering samples incorporating laser logo marking, customized firmware boot identifiers, and tailored packaging can be manufactured and shipped within 7 calendar days.
Smart rings cannot be resized after production. Manufacturers provide matched Sizing Kits (typically US standard sizes 6 through 13) containing unpowered plastic ring dummies. Brand clients distribute sizing kits to consumers first, aggregating precise size distributions before triggering final hardware packing.
For the European Union, products require CE (Radio Equipment Directive 2014/53/EU), RoHS (restriction of hazardous substances), and REACH compliance for skin contact. For the United States, FCC Title 47 Part 15 Subpart C certification is compulsory. For air shipment, UN38.3 test reports and MSDS are required for the curved lithium battery.
Yes. Turnkey ODM services provide a complete private-label companion app for iOS and Android. This includes updating brand colors, logos, UI iconography, localized languages, independent Apple App Store and Google Play developer account publishing, and optional enterprise server API endpoints.
High-density curved lithium polymer cells (typically 18mAh to 24mAh) sustain approximately 500 complete discharge and recharge cycles before dropping below 80% original capacity. Under normal continuous usage (continuous heart rate, sleep monitoring, dynamic SpO2), a single charge lasts 5 to 7 days.
Rather than relying on mechanical silicone gaskets which degrade over time, high-reliability rings utilize structural epoxy potting or high-pressure reaction injection molding (RIM). The PCBA, battery, and optical sensors are vacuum-sealed inside a solid resin core, preventing fluid leakage even under 50 meters of water pressure.
Modern architectures incorporate three primary optical wavelengths: 525nm Green LED (optimal for active heart rate and pulse tracking during exercise due to high hemoglobin absorption), 660nm Red LED, and 940nm Infrared LED (penetrating deeper into capillary beds for nocturnal pulse oximetry, HRV, and sleep staging).
Bulk production typically requires 15 to 25 calendar days depending on order volume and custom surface treatments (such as specialized DLC or physical vapor deposition gold/rose gold coatings). Full quality control reports and batch inspection logs are provided prior to warehouse dispatch.
