Health Measurement Migrates From Premium Wearables Into Mainstream Devices
Pulse oximetry, electrocardiogram sensing, and skin temperature measurement began in flagship wearables and are now appearing across mid-tier bands, earbuds, and rings. What travels with them is the regulatory clearance that makes the measurement claimable, and that clearance is what protects pricing when the component itself becomes ordinary. Optical biosensing grows at 12.3% on this migration. The commercial effect is unusual for a semiconductor category: the barrier to entry is a submission file and clinical validation data rather than a process node, which favours suppliers with regulatory affairs capability over those with fabrication advantage.
Market Impact: Holds erosion under 2% annually
