Introduction to B2B & White Labeling solutions

Core body temperature for B2B & White Labeling | This note presents how a standalone core body temperature sensor can be effectively integrated into various applications as a B2B and white labeling solution.

What is Core Body Temperature ?

Core body temperature is an important vital sign because it refers temperature of the body’s organs. Thus, it is a choice parameter for determining an individual’s health status. Resulting from various physiological processes, such as circadian rhythm, menstruation cycle, illness or physical activity, core body temperature fluctuates.

Many devices on the market attempt to estimate core body temperature via skin surface temperature. Due to the complexity of thermal regulation and environmental conditions, this estimate does not come close to the accuracy and reliability of greenTEG’s Core Body Temperature Sensor.

Thus, greenTEG offers the world’s first core body temperature sensor for continuous and non-invasive measurements on the upper-arm and chest body positions suited for B2B & White Labeling purposes.

For which applications, Core Body Temperature monitoring can be used ?

Continuous and non-invasive core body temperature monitoring is important for a broad range of B2B use cases:

workplace health and safety monitoring
Workplace Health & Safety

Workforce Health and Safety for Oil and Petroleum industries, Firefighting and military activities… including Heat stress prevention by detecting early signs of health-disorders and provide a better protection and prevention.

Variations of core body temperature often provide insight on health-related problems prior to the appearance of other symptoms. Remote and accurate patient monitoring to provide technological support to caretakers in various environments from Hospitals to Elder Houses.

Early Detection of Health Disorders

Early Detection of Health Disorders can be provided by analysing an individual’s Circadian rhythm. In fact, many significant health issues leave signs in a person’s natural day-night temperature cycle, also known as the circadian cycle.

Sport Performance Evaluation can be performed by monitoring an individual’s core body temperature during high-intensity activity or sport. This will allow you to gain valuable insights to increase athletes’ or amateurs’ performance and avoid dangerous situations like heat strokes. More about Core Body Temperature for Sports here.

How to get started using greenTEG’s solution for B2B purposes ?

Our solution designed for B2B & White Labeling

The combination of a miniaturized sensor and AI-based algorithm are the backbone of our B2B/white labeling solution: CORE Body Temperature monitor as a stand-alone wearable and off-the-shelf solution.

Accurate technology

Our patented novel sensor allows to accurately monitor core body temperature just through skin contact.

Artificial Intelligence Algorithm

CORE uses a machine learning based algorithm to calculate and analyze core body temperature in real-time.

Comfortable and lightweight

The device is easily mounted on a chest strap or attached with a medical grade patch. It is water-resistant and can be sanitized using alcohol.

Connect with your device(s)

CORE connects wirelessly with Garmin, iOS and Android smartwatches and smartphones as well as various gateways.

Constant monitoring

Long battery life allows monitoring core body temperature for longer periods (over 6 days) without interruption.

ANT+ & BLE compatible

Multiple patches can be operated with the same smartphone. The BLE standard temperature profile allows to stream the data on any BLE compatible device. Various gateways available.

This patented technology has been developed for more than 7 years. It is based on greenTEG’s heat flux sensor and targeted for the integration into the upper arm, and chest-based wearables. The technology has been proven suited for mass manufacturing, currently seen with CORE, which so far has been manufactured in volumes of ten of thousands devices.

The clinical-grade accuracy according to ISO 80601-2-56:2017 is currently in validation by different hospitals and universities. Internal studies (chest-worn and upper-arm validation studies).

Process & Expertise for getting started

Our team of experts will accompany you in the deployment and go-to-market of your solution with a set of engineering consulting hours (if needed) to accelerate your project.

Expertise & Capabilities

  • CORE API available for easy integration into your own app
  • Versatile integration into various apps and gateways
  • In-depth integration expertise from numerous in-field testing use cases (e.g. Military, Hospital…)
  • Various customization options available (App design & Packaging)

Depending on your application, our integrated technology can be used with two apps, CORE app and CALERAresearch:

  • CORE App for Sport Science and Performance – The app can now deliver all CORE sensor users with live and historical core body temperature data and advanced insights. The CORE app has been thought for daily users of the core body temperature monitor, with a focus on endurance sports athletes.

  • CALERAresearch app for research and B2B applications – The app and its additional tools (USB COREtool) have been developed for researchers and B2B customers which require a more in-depth analysis of their temperature data with large volume of data from multiple core body temperature monitors.
