Our project aims to measure the impedance spectrum of blood noninvasively by leveraging blood’s ability to transport heat by bulk motion, along with its temperature sensitivity. A small heater can introduce a periodic temperature variation from the skin surface, which manifests as a downstream impedance variation, which in turn can be measured using skin-surface electrodes.
