Family Loss Brings About Medical Breakthrough - Wearable Sleep Monitor

When he was in college, Hong Yeo's father died in his sleep from a heart attack, and Yeo changed his academic and research efforts as a result. Now, he and his research collaborators have developed a device that monitors vital signs during sleep, and it's the type of thing that may have helped doctors intervene in his father's illness if it had been available. This Sleep Scan device is a type of mask you can easily take on and off, and it has now been tested with human subjects and is close to being available commercially.
