Getting back to work was not so bad after the holidays; we had some very good news in our inbox. In 2017 we had already the pleasure to announce that the validity and reliability of the myTemp ingestible core temperature capsule was studied and published with very good results. You can read this article here. But the start of 2018 was not bad either with the good news that this week a scientific article is published by Medicine and Science in Sports Exercise comparing the myTemp ingestible capsule to three competitors in the field; CorTemp, VitalSense and e-Celsius. The aim of this study was to examine the validity, reliability, and inertia characteristics of four commercially available ingestible telemetric temperature capsule systems in well-controlled ex vivo circumstances using a water bath. Data from this study provide insight into which telemetric capsule system has the most favorable characteristics for core temperature assessment, which could enable researchers and trainers to select the best temperature sensor for their scientific study and/or daily practice. In this study the myTemp capsule performed excellent and proved that the capsule is a reliable and valid device to measure core temperature. Interested in the results? You can download the full article from our website.

Telemetric temperature capsule systems are wireless, relatively non-invasive and easily applicable in field conditions, and have therefore great advantages for monitoring core body temperature. However, the accuracy and responsiveness of available capsule systems have not been compared previously. Therefore, the aim of this study was to examine the validity, reliability and inertia characteristics of four ingestible temperature capsule systems (i.e. CorTemp, e-Celsius, myTemp and VitalSense).


We like to thank the Department of Physiology of the Radboud University Medical Center Nijmegen, the Department of Human Movement Sciences, Faculty of Behavioural and Movement Sciences, Vrije Universiteit Amsterdam, TNO, CBRN Protection/Training and Performance Innovations and Liverpool John Moores University for including us in this study. It’s very helpful in our next steps in 2018.
