Purpose

The transducer and electronics of an ultrasound probe can be significantly optimized and simplified by careful design for a specific application. The FloPatch uses continuous wave Doppler ultrasound, with relatively simple electronics to produce a pressure wave from one of two identical transducers and process the echoes received by the other. We have developed functional prototypes with a miniaturized, wearable form factor and demonstrated their ability to measure changes in carotid blood flow. The challenge now is to make the device low cost, and therefore commercially viable.
