Pro non-invasive wearable core body sensors that work with apps

Measuring body temperature is essential in many cases and is the main parameter of the body’s wellbeing. Each person’s normal body temperature may differ slightly, usually around 36.5 degrees Celsius with 0.5degrees variation. Normal temperature also depends on gender, location, and time measurement.

However, not all methods are convenient and robust. Casual temperature measurement devices take a single reading either through contact or contactless. It is inconvenient to keep measuring temperature if you want to track its fluctuations during the time.

Why measure Core body temperature?

Regular temperature readings with conventional infrared or contact thermometers take only skin temperature. Core temperature indicates the heat level inside deep structures of the body, such as the liver and other organs. Core temperature variates in a narrower range, and its significant change can disturb normal processes. Core body temperature could be measured with a catheter, swallowable pill, or other rectal probes.

You can find several solutions that measure core body temperature, but not all are so robust and smart. The wearable core body temperature sensor appears to be the right pick as it packs innovative technologies within a small form factor that does not intervene in daily routine.

The core body temperature sensor packs a thermal sensor which, with the help of an AI algorithm, is constantly optimized during usage. Using algorithms, it can read core body temperature (different from reading skin temperature). The only accurate way of temperature monitoring was swallowing a temperature monitoring pill, which would cost $70.

Core sensor characteristics

The sensor dimensions are 50x40x8.35mm and usually is fitted with a chest strap. Lithium-polymer battery ensures six days of continuous operation and can be recharged via USB cable. The total weight of the battery is 12 grams. The case is waterproof up to 1.5m. The sensor accuracy reaches ±0.21 degrees of Celsius. The sensor comes with Bluetooth BLE and ANT+ connectivity. The temperature sensors can be paired with heart rate monitors during intense training.

The Core sensor App

The core body sensor takes a reading once a second and sends data to a smartphone application where you can see an ongoing chart of temperature changes. The app is designed to keep all your reading history where you can use this data for later analysis. You can set various alerts to prevent overheating, and athletes can adjust their pacing according to body heat.

Also, you can:

• View all your historical temperature data
• Core body temperature trends – daily max, min, and average temperatures
• Weekly thermal load (time in heat training zones)
• Daily chart of adequate heat training time
• Daily temperature histograms

They all support multiple platforms, including iOS, Android, WatchOS, Wear OS, and Garmin ConnectIQ.

Typical Core sensor use cases

The temperature sensor was designed with athletics in mind, and its primary purpose remains heat training and monitoring thermal loads. However, there are much more areas where the Core body temperature sensor can be effectively used.

Workplace health and safety monitoring. There are many dangerous works where heat monitoring could save lives and prevent injuries related to overheating. Not all people withstand workloads equally; thus, collecting temperature data allows for adjusting workloads. There are many jobs where workers face heat, such as firefighters, welders, or miners, where heat stress is at high risk.

Body temperature monitoring when sick. Fever is one of the common diseases when temperature monitoring is crucial, and temperature is one of the leading indicators of a patient’s health status. The core sensor is an accurate and non-invasive device that is very convenient for continuous monitoring. Sensors via an app can send warning signals of elevated body temperature and identify rising problems in the early stages.

Sleep monitoring. The temperature fluctuates during sleep, and some studies show how temperature peaks are related to the circadian cycle. Tracking temperature during sleep can indicate burnout syndrome, sleep quality, and early diagnostics of upcoming diseases.

General purpose body temperature monitoring. Body temperature is an essential parameter that, along with other readings, can be used to determine rising health problems and indicate your physical activity level. Smartwatches are not great for temperature monitoring because of a lack of good contact with skin. And there is no core temperature measurement due to the wearable location on the wrist. If there are watches with temperature readings, they can only read skin temperature. In this case, strapped securely to the chest, the device can guarantee the best lessons.

Core body temperature monitoring is becoming a norm when training and performing sports. However, regular people measure core body temperature only when sick and with the help of a physician, and we don’t feel the need to check core body temperature continuously. However, there are many cases where monitoring it would prevent overheating during work or training, help to improve sleep quality and detect thermoregulatory diseases in their early stages. This non-invasive Core body temperature sensor is excellent for professional readings using the best innovative technologies available.
