CALERA technology from sports tech firm greenteg is claimed to be… ‘the most accurate sport wrist algorithm that gives athletes more convenience in measuring core body temperature.’
Core body temperature monitoring helps prevent overheating – monitoring and improving physical performance as the body temperature increases and for more effective cooling. As temperature behaviour is individual, the ability to monitor temperature with a high level of accuracy means that sporting activity can be undertaken far more effectively.
The core body monitoring solution developed by greenteg is conventionally positioned on the torso. For convenience in everyday activity, a wrist-worn monitoring device (such as inside a sports watch) is seen to be more appealing.
With this in mind, greenteg has developed a sport wrist algorithm to cater to the convenient wrist worn position for tracking core body temperature during training and high intensity sports activity.
An internal validation study was conducted to verify the accuracy of the algorithm. 16 volunteers participated in this study and engaged in physical activities under various conditions. This reportedly found that the greenteg model offers a precise core body temperature solution for the wrist.
A release from greenteg added.. ‘The algorithm compensates for environmental thermal influence, with an accuracy bias of 0.02°C, a limit of agreement of 0.83°C and a mean absolute error of 0.34°C. This level of accuracy is comparable with current state-of-the-art fever clinical external thermometers.’
“Our wrist algorithm presents an innovation in monitoring core body temperature for high intensity activity,” said Dr Lukas Durrer, Co-founder and Vice President of greenteg.
“The integration of the CALERA technology into smartwatches will help active people to improve their performance in heat, improve the immune system and get a better understanding of their own individual heat behaviour.
“This is a breakthrough that demonstrates our continuing commitment in our thermal sensing technology research; thereby expanding the possibilities for integration across a range of different scenarios.”
The CALERA technology has been developed so that it can be easily integrated into sports and other wearable devices. The company added that the release of these new capabilities signals a step for greenteg towards new and rewarding partnerships and opportunities.
