Droplet is a smart hydration system that reminds you to drink. This hydration solution includes the light & sound reminder base, one mug, one tumbler, and two flow control lids. Dehydration is a silent killer. Studies show that dehydration can cause falls, and acute kidney injury, increase hospital admissions and even contribute to deaths in elderly patients. With this in mind, gentle visual and verbal reminders with personalized messages built into the mug may remind the user to drink, possibly minimizing the health risks above.
