At CES 2017, Luc Pierat, Founder and CEO of PKvitality tells how K’Track Glucose, a watch-like fitness monitor with an added sensing module can calculate glucose without drawing blood by sampling interstitial fluid just below the skin with a chemical sensor. The Glucose K’apsul biosensor fits into the base of the device and effortlessly probes and tastes the user’s skin to produce a reading in about one minute.
