The Window into Endocrine Health.
While others measure at the periphery,
we moved closer to the source.
The superficial temporal artery runs upward behind the ear, approximately 1 mm beneath the skin’s surface. This superficial positioning enables direct capture of vascular and thermoregulatory dynamics.
Because these signals are tightly coupled to endocrine regulation, sleep, exercise response, and metabolic state, the posterior ear provides a stable and information-rich window into real-time physiological change.

From clinical validation, to real-time hormonal intelligence.
Our peer-reviewed clinical research conducted over multiple months in a free-living cohort establishes the posterior ear as a novel and reliable site for advanced physiological monitoring.
This data powers our proprietary Real-Time Hormone Tracking engine, mapping these signals to complex endocrine transients.
