Mizu | Hydration Tracker
Certain patients at the University of California, San Francisco Medical Center must heavily restrict the amount of water they consume, or risk getting severely sick. We prototyped for the medical device R&D team at UCSF a low-cost device that could monitor patients' water intake. I designed and prototyped the enclosure and capacitor that measures the change in water level.
Mizu is a parallel plate capacitor that measure changes in the water bottle's weight as the distance between the parallel plates changes. After calibration, changes in capacitance can be correlated with changes in weight of the water bottle as water is consumed.
Thanks for your time.
