Cardinal Health has asked the team to design an inexpensive, partially disposable flow sensor with a small footprint for a next-generation medical IV set. Current solutions rely on pressure sensors, which may not have a fast response time. The team has implemented and tested a thermal timeof-flight sensor capable of measuring a large range of flow velocities, and has designed a chip sensor suitable for medical applications.
