Increase participation in your research

Testing hypotheses is impossible if you can’t measure the right data or recruit subjects to participate in a study. The gastrointestinal pill might be more practical than a rectal probe and a good means of reliably measuring a person’s core body temperature (CBT), but it is invasive and too costly to scale. This means it can be difficult to get subjects to participate in your research or for budget holders to agree to its use.

Make Bodytrak your research partner

Make Bodytrak your research partner

We understand your requirement for high-quality data without having to sacrifice the comfort and participation of your subjects. Whether you’re running a university research facility or state-of-the-art laboratory, our easy-to-use data collection tool effortlessly tracks CBT, heart rate (HR), heart rate variability (HRV), physiological strain index (PSI) and additional metrics to help answer your research questions.

Non-invasive and comfortable

Backed by data

Bodytrak is driven by optimally located physiological sensors and software algorithms to enable accurate references of physiological parameters CBT, HR, HRV and PSI. Timestamped data can be exported directly from the Bodytrak platform via .csv file. Bodytrak has been used successfully in controlled laboratory trials with high profile organisations.


Bodytrak is a multi-use solution which can be used on multiple subjects and comes with a 2-year warranty as standard, with options to extend this. Combined with a real-time interface and high-resolution data export, this makes the solution very cost effective for research studies.


Does the Bodytrak device come in different sizes?

The Bodytrak Earpiece wingtip comes in 4 sizes - extra small, small, medium and large. The Hear:Thru earbud is available in one size and is fitted as standard.

If hearing protection is required the Hear:Safe earbud can be used and is available in 2 sizes - small and large.

The CommPack is available in one size and is smaller than a smartphone.

What kind of data is Bodytrak gathering?

The Bodytrak solutions focuses on capturing the following data;

  • Core Body Temperature
  • Heart rate
  • Heart rate variability
  • Physiological Strain Index
  • Fatigue
  • Man down
  • Noise exposure
  • Geolocation
Who can see the data collected by Bodytrak?

The data collected by the Bodytrak device is secure and protected using industry standard protocols. Only people who have authorised access within the organisation will be able to view the information.

Who owns the data that the device gathers?

The client owns the data. Bodytrak complies with GDPR and HIPAA compliance. The Bodytrak solution can display and record data for trend analysis. Alternatively, Bodytrak can simply provide live data alerts without any data being recorded - please speak to the Bodytrak support team if this is required. The Platform is fully configurable.

How accurate are the readings taken by Bodytrak?

Bodytrak captures real-time physiological data using in-ear sensors, analysed by machine learning (ML) on the device and in the cloud to provide critical insights. Due to its close proximity to the hypothalamus, the temperature control centre of the body, and since the eardrum receives its blood supply from the carotid artery, the ear is an excellent body site to measure core body temperature and heart rate accurately.

Heart rate data from Bodytrak shows a mean absolute error of 2.87 beats per minute compared to a control ECG device, and CBT data from Bodytrak shows a mean absolute error of 0.18°C compared to a gastro-intestinal pill. Our fatigue scores have been validated during trials where mental fatigue, physical fatigue or drowsiness was induced to ensure precise data. This is a strong indication of the effectiveness of our solution.
