XTEMP demonstrated strong alignment with rectal reference measurements across 200 paired readings in a hyperthermia study conducted at Texas Tech University
Dallas, Texas – 04/25/2026. BlinkThermal today announced a major clinical testing milestone for XTEMP, its noninvasive thermal sensing platform, following recent study work conducted at Texas Tech University in a controlled austere heat environment.
In the study, performed at 35°C and 40% humidity, XTEMP closely tracked rectal reference measurements across 200 paired readings, with a reported Pearson correlation of 0.938 and an average gap of approximately 0.22°C.
This milestone marks an important step in the advancement of noninvasive core temperature monitoring under demanding environmental conditions. The results demonstrate XTEMP’s ability to reflect physiological temperature changes with strong consistency against an invasive reference standard, supporting the platform’s potential to expand access to core temperature insights beyond traditional clinical settings.
“BlinkThermal was founded on the belief that core temperature monitoring should not be limited by invasiveness, complexity, or setting,” said Dr. Senay Tewolde, CEO. “These findings represent a meaningful validation milestone for XTEMP and reinforce our vision of delivering clinically relevant thermal monitoring in environments where conventional methods are not practical.”
The clinical-test work was conducted in a hot environmental chamber designed to simulate austere conditions and was funded by the U.S. Air Force. While this phase represents an early but important dataset, the outcome provides encouraging evidence that a contactless, noninvasive approach can closely track the physiological changes typically measured through invasive core temperature monitoring methods.
BlinkThermal is continuing to build on this milestone through expanded clinical validation efforts, including IRB-approved testing across 40 human subjects, with the goal of further strengthening performance data and advancing XTEMP toward broader real-world application.
The company sees applications for XTEMP across environments where real-time, reliable thermal monitoring is critical, including homecare, field operations, performance settings, occupational heat exposure, and next-generation health monitoring. BlinkThermal believes this progress could help open a new chapter in temperature monitoring by supporting more practical, scalable access to core thermal insights across both specialized and everyday environments.
“We see this as more than a technical milestone,” BlinkThermal added. “It is an important signal of what becomes possible when hospital-grade thermal insight can begin moving beyond the hospital.”
