Cosinuss c-med° alpha
A CE-marked in-ear vital-signs monitor used in mountain rescue and military medevac — the ear canal beats the wrist for motion and core readings.

In-ear, not all-day consumer
An ear-canal sensor that continuously measures heart rate, SpO2, core-adjacent temperature and respiration. Because the ear is fed by the carotid system, readings resist the peripheral shutdown that defeats wrist sensors in cold, shock or sepsis.
What it measures
Continuous heart rate, blood-oxygen saturation (SpO2), ear-canal (core-proxy) temperature and respiration rate from a single in-ear probe.
Regulatory status
CE Class II medical device. Deployed in Austrian mountain rescue, Ukrainian military medical evacuation, and COVID-19 remote monitoring.
Validation & accuracy
Field-proven in austere, high-motion settings where wrist optics fail; the ear site is hemodynamically closer to core perfusion and resists vasoconstriction artifacts.
Data control & export
Raw data: restricted — streams into clinical/remote-monitoring platforms rather than a consumer export. API: clinical/integration-oriented, not a public consumer API.
Wearability & battery
A small in-ear sensor worn during activity or monitoring episodes; built for resilience to motion rather than 24/7 consumer comfort.
Cost & access
Sold through clinical, rescue and research channels rather than retail; price is deployment-dependent.
Who it serves
Patients and responders needing reliable vitals in motion or extreme conditions where wrist sensors break down.
Who is left out or burdened
Not a mainstream consumer buy; data lives in clinical pipelines; in-ear form factor isn’t for everyone.
✓ Strengths
- CE Class II in-ear medical device
- Ear site resists motion and peripheral-shutdown artifacts
- Proven in mountain rescue and military medevac
- Continuous core-proxy temperature + SpO2
✕ Weaknesses
- Not a retail consumer product
- Data confined to clinical pipelines
- In-ear form not for all-day wear
- No open consumer API/export
70
Why this clinical score. A CE-marked, field-deployed vitals monitor whose ear-canal site delivers genuinely clinical signal fidelity in conditions that defeat wrist wearables.
45
Why this empowerment score. Data flows into clinical and remote-monitoring systems with no open consumer export or developer API, holding empowerment mid-low.
40
Why this everyday score. Engineered for rescue and monitoring rather than all-day living, so everyday breadth is limited despite the strong sensing.
Reviews & coverage
Coverage frames the c-med° alpha as a rugged in-ear vitals monitor proven in rescue and military medevac, valued for resisting motion and peripheral-vasoconstriction artifacts. It is a clinical/field tool rather than a consumer wearable, so reviews focus on deployment reliability over apps.
