Abstract
THIS PROJECT WILL DEVELOP A THERMAL PROBE TO NONINVASIVELY MEASURE LOCAL BLOOD PERFUSION IN TISSUE. THE DEVICE WILL CONSIST OF A SINGLE PROBE THAT CAN BE ACTIVELY HEATED OR COOLED AND PUT IN CONTACT WITH THE SKIN. THIS CREATES A TRANSIENT HEAT FLUX, WHICH IS MEASURED AS A FUNCTION OF TIME. TOGETHER WITH A SIMULTANEOUS MEASUREMENT OF THE SURFACE TEMPERATURE, THIS ALLOWS CALCULATION OF THE THERMAL DIFFUSIVITY AND LOCAL PERFUSION OF THE TISSUE. RECENT DEVELOPMENT OF A NEW TYPE OF HEAT-FLUX GAUGE MAKES THIS NEW BIOMEDICAL TECHNIQUE POSSIBLE. THESE MICROSENSORS HAVE BEEN PRODUCED AND SHOWN TO WORK. THIS RESEARCH WILL APPLY THESE SENSORS TO PROBES THAT CAN BE USED FOR A WIDE VARIETY OF NOVEL MEASUREMENTS IN LIVING TISSUES.
