A group of scientists from South Korea have not only created this but they have taken the self-monitoring theory to a new level. They have made a responsive patch that delivers a course of treatment which means that when the patient needs a stronger dose or the ailment has been cured, the correct dosage will be applied accordingly. The rectangular patch is 2-inches long and made of stretchable nano-materials. Within the materials are heat-activated silica nanoparticles that monitor muscle activity and release therapeutic agents according to the body temperature of the patient.
