§ 01 — MATERIAL COMPARISON

Grade-5 Titanium vs Common Wearable Materials

Not all metals are equal. Grade-5 (Ti-6Al-4V) combines titanium with 6% aluminium and 4% vanadium — the exact specification trusted in jet turbine blades and surgical heart implants.

TI-6AL-4V ALLOY

Grade-5 Titanium

Combines unmatched strength-to-weight ratio with 100% skin biocompatibility. Inert to sweat, salt water, and skin oils.

Tensile Strength 950 MPa

Lightweight Efficiency (Inverse Density) 4.43 g/cm³

Hardness Rating (Mohs Scale) 6.0 (9.5 with DLC)

Biocompatibility Rating: ISO 10993 Surgical Grade (Hypoallergenic)

§ 02 — MANUFACTURING PROTOCOL

From 28g Ingot to 3.6g Precision Ring

STAGE 01 OF 05

Grade-5 Titanium Billet Selection

Every Ring R1 starts as a solid 28g rod of Ti-6Al-4V titanium. Laser scanned for micro-fractures before carving.

§ 03 — BIOMETRIC SIGNAL SCIENCE

Why the Finger Outperforms the Wrist

30 years of clinical photoplethysmography (PPG) research proves that digital arteries in the finger sit directly beneath thin epidermis with high capillary density — offering up to 100x cleaner pulse wave resolution than the radial wrist artery.

Signal Clarity: 99.4% (Clinical PPG Grade) Motion Artifact Interference: < 0.5% (Minimal)
