The California Academy of Mathematics and Science (CAMS) InvenTeam is inventing a device called the Swim Monitor, a wearable anti-drowning device that works in conjunction with an external smart-phone app. The beneficiaries are parents with children ages 6 and up. With its sensors, the Swim Monitor regularly monitors the child's oxygen levels and pulse readings while they swim. When irregularities are detected, indicating the child is in potential danger, the Swim Monitor sends an alert to the app and deploys the onboard wrist-mounted flotation device to keep the child buoyant until help arrives.
