In recent years, the annual CES in Las Vegas has been the place for companies to announce what they think will be the next greatest wearable. While we’ve typically been less than impressed with the new offerings in 
past years, PKVitality showed off what we think is the best one so far.
Dubbed “K’Track”, this wearable wristband has the looks of a common smartwatch, but the functionality of a glucometer. Underneath the watch face where you typically find a heart rate sensor is a special sensor unit called the “K’apsul” consisting of an array of tiny micro-needles. These microneedles painless penetrate the topmost layer of skin and analyzes the interstitial fluid. The medical version of the wearable, K’Track Glucose, monitors the user’s glucose levels, while the fitness version, K’Track Athlete, measures the amount of lactic acid in the interstitial fluid. K’Track syncs with a iOS or Android device and can be programmed with alerts and reminders and trends.
Once approved, K’Track Glucose will retail for $149 and K’Track Athlete will retail for $199. Additional K’apsul sensor units, which can take unlimited measurements but only last 30 days, will retail for $99.
