Yeast, Its Not Just For Bread Anymore

Everyone has heard of medicinal patches, stick it on and the medicine is absorbed through the skin. They are used for pain meds, heart meds, even nicotine to stop smoking. Not all medicines can be absorbed through the skin easily though. Piercing the skin to allow absorption is necessary. But what would power the micro needles needed to administer these other meds? How about yeast? Activate the yeast chamber and it produces carbon dioxide that forces the micro needles into the skin. A very clever idea, if it works they will make a lot of dough from yeast this way.
