Researchers develop a medical wearable using a pencil and paper

A team of researchers from the University of Missouri have developed a medical wearable by using pencil and paper. They claimed that pencils cores are made from more than 90% graphite and are capable of conducting a significant amount of energy when writing on paper. This means that the graphite can be used as a sensing electrode, and can be placed anywhere on the body and fold around the body part and skin.
