Live Poll

Would you use an attachable health sensor to track your daily health metrics?

Startup Hiyd has unveiled a health-tracking sensor designed to attach directly to traditional wristwatches using microsuction technology. The device allows users to monitor various health metrics without needing to purchase a dedicated fitness tracker.

Why it matters

The company aims to provide comprehensive health data to consumers who prefer the aesthetic of their existing timepieces. This approach seeks to bridge the gap between traditional horology and modern wearable fitness technology.

The Hiyd sensor measures 2.7 mm in total thickness and weighs 7 grams, with a 0.3 mm microsuction interface. It tracks metrics including heart rate, heart rate variability, sleep staging, movement, calories burned, and VO2 max.
