Core body temperature is one of the crucial signs of our bodies. It fluctuates and changes with the body’s natural rhythms, such as those caused by sleep/wake cycles, menstruation, sickness, and exercise. For this reason, we need to know more about the internal and environmental factors that influence these naturally occurring systems. Fortunately, sensor technologies have improved patient comfort and accuracy and created better instruments for monitoring through advancing body temperature measurement. Increasingly, more people and sports teams can get their hands on wearable sensors. Thanks to technological developments, endurance athletes, coaches, and doctors can now track movement patterns, stresses, and biometrics in real-time to optimize performance and reduce the risk of injury.
Best sensors for measuring body temperature
NTC Thermistor Sensors
The negative temperature coefficient refers to NTC. An NTC thermistor uses metal or ceramic composites’ resistance features to monitor the temperature. The benefits of the broad spectrum of NTC temperature sensors are their small size, durability, reliability, and accuracy. Furthermore, there are several uses of NTC temperature sensors, regarding healthcare, they are used in medical equipment, patient monitoring, and catheters for temperature measurement and control in patients.
Digital Temperature Sensors
The precision of digital temperature sensors for measuring body temperature is unmatched in the industry at 0.1 degrees Celsius. These temperature system sensors can react swiftly to temperature fluctuations of the process. You may get these sensors in small packages built particularly for confined places. Whenever a factory-preset trigger level is reached, digital temperature sensors function similarly to thermostats in changing the state of their outputs (either push-pull or open-drain).
Thermal Energy Transfer Sensors
Thermal energy transmission is what we perceive as humans on the skin, not the actual temperatures. For example, objects made with different materials, such as wooden and metallic, can be felt on the surface at different temperatures, but actually, they are at the same temperature. You’re truly feeling is the transfer of energy. Metal removes more energy from your body when you contact it than wood does. The thermal energy transfer sensor can measure the amount of energy passing through the skin. When the heat passes through the sensor, it generates a voltage signal proportional to its energy. So, the sensor detects the heat and energy from or into the body, and an algorithm processes the data to calculate core body temperature in real-time. The collected data of the core body temperature, altogether with the data on heart rating, can help people in understanding more about body temperature and body system accurately.
Thermopile Infrared Temperature Sensors
Thermopile sensors can estimate temperature from a considerable distance by sensing an object’s infrared radiation. The temperature will rise when there is a higher release of infrared radiation. The thermopile pressure sensor uses tiny thermocouples mounted on a piece of silicon to convert the energy into an output signal. A reference sensor is included within the device to serve as a calibration point. These sensors enable accurate non-contact temperature readings, and they are used in various sectors such as health, for medical equipment.
What Do Sports Scientists Think About Core Body Sensors in Training?
Earlier, the only method to know your accurate core body temperature was to take a thermometric pill and monitor its progress through your system with a separate device. However, experts believe this is no longer an issue, thanks to the core body sensors, which keep tabs on your internal body temperature by detecting thermal energy transmission (rather than relying on an equation determined from the temperature of your skin). As sports scientists constantly research the best devices, from CORE Body Temp customer reviews, they got to know how endurance sportspeople are relying on this sensor. Numerous athletes, trainers, and sports scientists have used these sensors to gain insights, resulting in better dealing with heat, training, acclimating to the heat, cooling themselves, and racing strategically.
Sports scientists believe that core body temperature sensors have the potential to alter all that by making continuous monitoring of internal body temperature possible through the use of a minor, lightweight, and comfortable wearable device. These sensors accurately assess your internal temperature by monitoring the amount of heat lost through the skin. The sensor you attach to your core is more than just a thermometer. It’s a miniature “energy transfer sensor” that tracks how much energy leaves your body and the surrounding environment. With a promised precision of +/-0.21 °C equivalent to actual internal reading, it usually entails sensing the heat loss from your body and interpreting that to determine your core body temperature. The true novelty of the core body sensor is that it makes body temperature monitoring accessible to more athletes by being compact, user-friendly, and inexpensive.
To Wrap Up
Your core body temperature measures your body’s capacity to generate and expel heat. Even when your outer body temperature fluctuates significantly, the body can maintain a stable internal temperature. To measure your body temperature with the latest sensor devices, choose from the list mentioned above, depending on the objective of the measurement.
