With so many companies offering wearable devices at this year's CES, perhaps it's apt that the best startup we saw at CES 2015 was a company that was taking a different approach to the fitness tracker. AmpStrip
is a health wearable that stays out of the way: a Band-Aid style strip that's waterproof and comes with disposable adhesive strips to attach right to your skin. Despite the slim profile, the company has crammed in an accelerometer, thermometer and heart rate sensor, which, in tandem, can monitor your heart rate, movement and activity. T-shirts are, apparently, optional.
