Cosinuss in ear sensor c-med° alpha
Accurate vital monitoring, measured directly in the ear – technology for real-time health monitoring.
The Cosinuss c-med° alpha is a highly innovative in-ear sensor that continuously and extremely accurately measures vital signs, including body temperature, heart rate, and oxygen saturation (SpO₂), through the integration of photoplethysmography (PPG). The sensor is worn comfortably in the ear, making it ideal for prolonged use in both medical and operational environments.
The ear is a particularly suitable location for measuring vital signs: it is well perfused, protected from environmental influences, and provides a stable temperature. The Cosinuss sensor makes optimal use of these characteristics and delivers measurements comparable to clinical-grade equipment.
The sensor also enables tactical medics to continuously monitor a casualty’s vital signs under demanding operational conditions, such as low-light environments and high-noise situations during evacuation by helicopter.
In summary, the display connected to the in-ear sensor currently shows:
- Photoplethysmography (PPG)
- Heart rate
- Oxygen saturation (SpO₂)
- Body temperature
In Q3 2026, an update of the in-ear sensor will add:
- Blood pressure
- Respiratory rate to the display.
User-friendly and multiple parameters integrated!
The sensor works seamlessly with the Cosinuss app or can be connected to existing systems via open protocols. Thanks to its lightweight and ergonomic design, the sensor is comfortable to wear, even during prolonged use.
Measurements are performed via peripheral pulsation in the ear canal.
Rechargeable via the included case using USB-C.
The case contains 2 in-ear sensors in two different sizes (Small and Medium recommended).
Each sensor has its own unique serial number for pairing with a specific smartphone or tablet.
Connection via Bluetooth.
The sensor battery lasts up to 12 hours, which is also the recommended maximum wearing time.
Applications across different fields
The Cosinuss in-ear sensor is widely used in situations where reliable monitoring is critical:
- Defense & first responders: Monitoring operational units under high-stress conditions, continuous monitoring of casualties, or use during testing and fitness assessments
- Healthcare and home monitoring: Early detection of fever, hypoxia, or cardiac arrhythmias
- Ambulatory care & hospital use: Continuous measurements without disturbing the patient
- Elite sports: Training optimization and recovery monitoring
Wireless communication via Bluetooth or dedicated gateways
Comfortable and discreet design, suitable for long-term wear
Real-time data transmission to apps, dashboards, or healthcare systems
CE Class IIa certified and medically validated
In Q3 2026, the Cosinuss in-ear sensor will receive an update that will also enable measurement and display of blood pressure and respiratory rate on the display/tablet.
