In 2014, wearable health tracking devices continued to get more creative, going far beyond simple fitness tracking. The K-Goal, a "Fitbit for your vagina," promised to help women do kegel exercises correctly, while the Emotiv EEG headset offered the prospect of mental acuity, measured by a device that tracks the brain's concentration.
Of course, kids came up with some of the most unique health innovations of the year. One 15-year-old came up with a wearable device that triggers an alert when his grandfather with Alzheimer's gets out of bed. Another young scientist put the finishing touches on a gel that can stop bleeding almost immediately—an invention that he first came up with as a teenager.
