Wearable fully non-invasive blood glucose and lactate monitor, no needles, no patches, and no pain. Providing simple 24 hour monitoring of blood chemistry transdermally through fully intact skin, and because we are measuring changes to the blood and not interstitial fluid we produce results as fast as a finger prick test without the finger prick, making us 15 to 20 min faster to respond to changes than the existing needle patches (Abbott Libre, Dexcom). Our technology is novel and protected by International Patenting. We see this technology offering significant cost saving to global healthcare providers making this an affordable option for addressing Type 1 & 2 Diabetes and for pre-diabetic users too. The ability to extend lactate monitoring to wider use within hospitals, emergency and primary care will have significant benefits to the outcomes for treatment of disease.
