Empower Accurate Core Body Temperature Monitoring
Non-invasive, continuous, and precise measurement for healthcare, fitness, and everyday well-being.
Track Core Body Temperature in your wearable
Core body temperature (CBT) is one of the most essential indicators of human health. From early fever detection to precise athletic performance tracking, CBT gives you actionable insights into the body’s internal state—far beyond what a simple skin or oral temperature measurement can provide.
Varmo Sensors has developed an ultra-compact heat flux sensor that enables easy, reliable, and continuous CBT measurement. By using our patented printing technology and specialized sensor design, we aim to make core temperature tracking widely accessible across consumer wearables, medical devices, and research applications.

Accurate Core body Temperature
Why Core Body Temperature Matters
Early Fever & Infection Detection: A slight elevation in CBT can be a first sign of infection or inflammatory processes.
Optimized Performance in Sports: Monitoring CBT helps athletes balance exertion, hydration, and recovery—especially in hot or humid conditions.
Sleep & Circadian Insights: Fluctuations in CBT are closely linked to circadian rhythms. Tracking these changes sheds light on quality of rest and overall wellness.
Women’s Health & Fertility: Small temperature shifts can indicate ovulation windows, helping those aiming to conceive or track their cycles.
Patient Monitoring & Safety: Continuous CBT data supports clinical decision-making for acute care, long-term monitoring, and managing high-risk groups during heat waves or strenuous tasks.
How Our Sensor Technology Works

Heat Flux Measurement
The sensor detects tiny flows of heat from within the body toward the skin. This reading is much less susceptible to quick ambient changes than surface-temperature-only measurements.

Skin Temperature Compensation
A built-in surface temperature reading (or integration with a precision temperature component) helps the system adapt to environmental shifts—ensuring accuracy in real-life conditions.

Advanced Data Processing
Machine-learning algorithms and advanced statistical models unify heat flux and skin temperature data, estimating true CBT minute by minute—without invasive probes or guesswork.

Continuous, Non-Invasive Monitoring
Because the sensor is printed in ultra-thin, layered sheets, it’s easily integrated into wearable devices. The result is real-time, medical-grade insights with minimal user effort.
