Solution for core body
temperature data collection
Gold standard for core body temperature data collection - Scientifically approved
The temperature variable is a key indicator of the subject’s physiological status. The continuous nature of the measurement is quite difficult to obtain and only a few restrictive devices (rectal, esophageal probes, etc.) allow continuous core body temperature data collection.
Dedicated to non-medical application, the eCelsius Performance solution makes possible to collect continuous, reliable and accurate core temperature data while preserving their subjects’ comfort and mobility.
The key elements of the system:
An electronic capsule, eCelsius Performance, ingestible and communicating.
The electronic capsule is delivered in unit package. Once activated, it communicates in real time, and continuously, the core body temperature data. The single-use eCelsius Performance electronic capsule is removed by natural way; it allows thus to collect the core body temperature over a period corresponding to the transit time (24-48 hours on average).
An activator
The activation box allows to take the eCelsius Performance electronic capsule out of standby mode; it allows to activate and associate it to the receiving device.
Two different equipment configurations allow to retrieve the data from the electronic capsule:
- ePerf Connect, a "Gateway”, receiving and storing the temperature data collected by the electronic capsule. ePerf Connect may be worn as a wristwatch; it sends the data in real time (or a posteriori) to an Android application (ePerf Mobile), using Bluetooth (BLE) protocol. The data can thus be displayed on the screen of the Smartphone or Tablet; the csv file can be downloaded from the device at anytime.
- eViewer Performance, a monitor, receiving and recording the data transmitted by the electronic capsule. eViewer Performance monitor only displays the last data data collected in real time. Through a wire connection (USB), data full access is provided thanks to a PC/MAC software (csv file) for archiving or scientific exploitation.
The communication distance between the electronic capsule and the receiving device ranges is around 1m (depending on environment and subject).
The electronic capsule has also its own memory. In case of a communication disruption between the receiving device and the electronic capsule, an automatic data synchronization is thus possible, a posteriori. The same receiving device can manage up to three electronic capsules simultaneously for extended use.

Key benefits
Designed by physiologists, the solution was developed to combine comfort and ease of use. The eCelsius Performance solution is currently the only solution on the market allowing continuous core temperature data collection without any constraint for the subject.
Thanks to the on-board memory in the electronic capsule, temperature data collection can be continuous, without the need to wear the monitor continuously.
Key advantages of the system:
Improve the conditions for subjects data collection;
Preserve ecological data collection condition (real life, competition, field exercise, ...);
Secure tests and protocols;
Reduce recruitment constraints;
Limit artifacts associated to the operator;
Improve decision-making through reliable and accurate data and access to a complete history.
Multi-parametric data collection
BodyCAP and Equivital have joined forces to offer to researchers a new multiparametric data collection solution: a simultaneous use of eCelsius Performance and eq02+ LifeMonitor solution is now possible.
Core temperature data
Heart rate
Respiration rate
Skin temperature
Activity
The Equivital – eCelsius Performance system keeps the successful key feature of eCelsius Performance: real time data collection and buffered core temperature data access.
Combined with Equivital’s eq02+ LifeMonitor, the solution gives you easy access to a multi-parametric physiological dataset.
The global solution allows to collect up to 8 subjects simultaneously thanks to its dedicated EQ-eViewer Performance monitor.
All data and parameters collected by both the EQ-eViewer Performance monitor and the eq02+ LifeMonitor can be downloaded, stored and analysed in the same file thanks to the specific software EQ-Manager.

Various applications: Sport & Basic Research
The eCelsius Performance solution meets the need for continuous core temperature data collection in many applications.
Basic research application
The temperature variable is regularly part of the “Primary Outcomes” in various research protocols. Continuous, reliable and accurate temperature data collection allows to secure the protocols without adding any constraints for the subject and the operator.
Cope with harsh environment
Long duration exercises performed in hot environment induce potential rise in core body temperature. The constraint is similar for subjects exercising in cold condition; a drop in core body temperature has to be anticipated.
Thermoregulation process efficiency evaluation
In the context of sports performance, thermoregulatory responses are very different among individuals. Objective measurement of the core temperature during exercise allows to individualize training processes. The eCelsius Performance solution allows individualization of heat acclimatization protocols and better preparation for competitions in hot environments.
Sleep
Core body temperature is a key indicator of the subjects’ biological rhythmicity. Continuous data collection of this variable allows the characterization of core temperature circadian rhythm, which is critical for sleep analysis.
