Abreu BTT™ 700 Research System

The first and only system to non-invasively and continuously capture temperature measurements or thermodynamic signals from the brain thermal tunnel (BTT)!

For researchers, students, and enthusiasts who seek to understand brain thermodynamics, our Abreu BTT™ 700 Research System captures and provides brain thermal signal analytics and visualizations. Researchers can use this system to track, analyze, and perform interactive analytics on brain thermal signals related to activities or experiments.

Abreu BTT™ 700 Research System

BTT™ Technology and Biology

The BTT is the only biologically natural site for accurate core temperature measurement.

BTT Corp provides the first continuous, noninvasive temperature measuring system for capturing temperature at the body site with the highest thermal conductivity – the fat-free skin that overlies the Brain Thermal Tunnel (BTT). The BTT enables the capture of brain thermodynamic signals for real-time analysis and development of pattern detection and predictive models.

Yale University conducted its own investigations and concluded that “The ability to monitor the oscillatory pattern of thermal signals with a high frequency sensor applied to the skin of the superomedial orbit (“brain temperature tunnel”) offers new avenues for assessment of temperature regulations in health and prediction of outcomes of diseases” and “Monitoring temperature at the skin overlying the path between the hypothalamus and the superomedial orbit (brain temperature tunnel) uniquely delineated temperature changes during sleep onset, arousal and awakening.”

What’s in the Abreu BTT™ 700 Research System?

The Abreu BTT™ 700 Research System can be easily applied and integrated into the researcher’s workflow, and includes everything needed to capture and analyze BTT thermodynamic signals.
