The National Science Foundation awarded a $250,000 Project Grant to the University of Colorado Boulder to support development of noninvasive, compact internal body thermometers under the Engineering program (CFDA 47.041). The two-year award running from May 2021 through April 2023 will fund efforts to create new thermometer technologies that can accurately measure core body temperature in a noninvasive and compact form factor. As part of its mission to improve engineering research and education, the NSF Engineering program supports innovative projects like this seeking to foster new medical device solutions and advance public health monitoring capabilities. The University of Colorado will deliver the agreed upon thermometer prototypes and related research under the terms of this federal assistance award.
