2017 will bring a flood of health-related wearables that should be able to live up to their claims, and PKvitality’s is among the first out of the gate. Its K’Track line of wrist-worn trackers uses microneedles to “taste” fluid just below the skin’s surface and analyze it for glucose or lactic acid.
The K’Track Glucose and K’Track Athlete use the same mechanism: a capsule of 0.5mm long needles that dig into the skin deeply enough to “taste” the fluid but not deeply enough to draw blood or cause pain. That interstitial fluid contains chemicals and biomarkers that the K’Track can analyze. Results are displayed on the device’s screen and on an app.
The K’Track Glucose is expected to retail for $149 with 30-day replacement capsules for $99. K’Track Athlete will sell for $199 with 30-day capsules for $149. No telling when you’ll be able to get it, though; the company says they’re waiting for FDA approval, for which they’ve applied.
