Get early warning signs of COVID-19 infection symptoms through on-time elevated body temperature monitoring

Fever is the most common initial symptom of Covid 19 with more than 98% of patients having fever symptoms at onset.¹ With our gSKIN® Body Temp Patch we can continuously monitor the core body temperature of individuals, enabling fever prediction², and providing data for early signs of disease. That data could enable a real-time tracking of the health status of risk groups.

Monitoring and detecting elevated body temperature in infected patients and exposed healthcare workers for pandemic control

Monitoring the core body temperature of general ward patients, releaving the healthcare system 


A functional sensor that monitors body thermal output on real-time.

At greenTEG, we build top-notch heat flux sensors that could be embedded into any device for core body temperature tracking. If you need more info about our field-tested technology applied to fever tracking, please download the datasheet for the gSKIN® Body Temp Patch, our latest device for research and evaluation purposes.

A proven algorithm that delivers reliable data

At greenTEG, we have also developed an algorithm to crunch the raw data gathered by the sensor into reliable insights for core body temperature tracking. Our algorithm has been tested both in clinical trials and live conditions, showing high accuracy compared to other temperature tracking methods.

Clinically validated accuracy

The accuracy of the gSKIN® Body Temp Patch monitoring solution has been validated in an independent clinical study and numerous internal case studies. Both clinical study and internal tests show an absolute deviation of 0.26°C, a 95% limit of agreement (LoA) of 0.67 °C and a correlation factor of 0.86. As a comparison, a standard ear thermometer shows a confidence interval of 0.5 °C but only when measured by a professional, at low activity and at room temperature.
