DermaTec is an early stage biotechnology startup that builds affordable and easy to use biosensors. Our first product is a patch which changes color as its wearer drinks alcohol and becomes intoxicated. This revolutionary product provides a platform to promote brands and responsible drinking. We market this product as a means to reduce out of control intoxication, the number of alcohol-related accidents, and the liability of event planners. This patch changes color using a chemical reaction with alcohol perspired through the sweat and is patented for use on the skin. This is manufactured like an adhesive bandage and worn like a sticker or wristband. It visibly displays to the wearer and others around them the color change as well as any brand message printed on it. The chemistry is interchangeable; thus enabling our ability to adapt the technology to the real time detection and electrochemical monitoring of the active chemicals in other selected drugs and disease biomarkers,
