Body temperature is a critical element for a healthy and well functional body since our body needs to maintain a specific range of temperature.
Core body temperature fluctuates daily following circadian rhythms. Body temperature also varies in relation to several environmental and biological factors, such as time of day, site of temperature measurements, level of physical activity, age, and sex, among others. Body temperature is kept in the normal range by thermoregulation, a set of complicated mechanisms orchestrated by the hypothalamus, a subconscious part of our brain that partly controls our central nervous system.
The human thermoregulation also has a defense mechanism, which fights against many kinds of diseases, infections, and other unwanted foreign invaders called the febrile response. However, physical activities can also severely affect body temperature, producing deviations that could be misinterpreted without adequate medical knowledge. Therefore, continuously monitoring the body temperature during the entire day, is a good method for understanding and enhancing knowledge about our health and wellbeing.
Continuous body temperature monitoring during the COVID-19
Fever is a common feature of disease
Several diseases caused by viral infections, including COVID-19, are characterized by multiple symptoms, including fever. Therefore, body temperature monitoring is a vital tool for the detection of infections such as this.
One of the most prevalent symptoms of COVID-19 is a rise in body temperature
COVID-19 cannot be diagnosed without a formal test, but it is widely accepted that the combination of the following two symptoms, could be an indication of a possible infection:
- Elevated temperature due to fever
- Persistent dry cough
For temperature monitoring, there are a number of disadvantages with the current methods, especially infrared forehead thermometer (1):
- Allow only for single-point measurements. Symptoms are not detected if there is medicine intake (i.e. an aspirin). Offset of symptoms is after measurement.
- Low accuracy due to ambient conditions or activities taken by individuals (i.e. hard work, sports).
- As the accuracy is low, the threshold is usually lowered in order to filter out potential infected individuals. That might cause many false positives.

Benefits of continuous monitoring
Continuous monitoring has many advantages compared to other methods:
- It avoids ‘point in time’ measurements which can result in issues with diagnosis or misdiagnosis. Repeated measurements, in fact, are already recommended by some researchers to prevent potential issues (2).
- At the same time, you can gather and process data in real-time, identifying trends for a better health assessment of individuals and groups.
Continuous body temperature monitoring for workforce protection
Dependable and remote screening of body temperature for all employees is needed
Employers have a duty to ensure their work environment is safe for their employees and clients to enter. This means introducing measures such as social distancing, regular cleaning, and continuous fever screening to detect and isolate potentially infected individuals as soon as possible and not only during the COVID-19 pandemic.
Continuous body temperature measuring solutions are currently the best fever screening methods available to guarantee the safety of your workforce.
Recommended by health authorities
The FDA in the United States already recommends to regularly perform triage in crowded places, monitoring fever as it is one of the most common signs of COVID-19 disease. For that purpose, the agency recommends using telethermographic systems.
It’s the new normal
At the United States, Walmart, Amazon, Home Depot, and grocery chain Bi-Lo have announced they will begin checking workers for fever at stores and warehouses.
Wearable, accurate and non-invasive device needed
For proper monitoring of the workforce, we need a wearable device that is also non-invasive. Otherwise, chances are that it won’t be feasible to use it during many situations in factories and office buildings.
At the same time, the device should compensate for environmental conditions to accurately monitor the body temperature. That feature is not delivered by those devices measuring skin surface temperature.
Hence, the device chosen should combine four elements: wearable, non-invasive, and capable of performing continuous and accurate measurements during free-living conditions.
CORE is the first device that combines a non-invasive wearable with continuous measurements of body temperature under real-life conditions with high accuracy
Easy to wear
A small wearable device that can easily attaches to the chest with a medical patch or a strap. It is also easy to disinfect and reuse by other users.
Our innovative and patented technology measures core body temperature based on the energy transfer from the body, a much more accurate method than skin-based temperature sensors.
Unlike ingestible pills or catheters, it allows monitoring the core body temperature without introducing any object in the body. It works just through skin contact!
The CORE sensor will continuously gather data for days, unlike ear or rectal temperature measurements with regular thermometers.
