Embeddable sensors that can track a person's vitals could eventually be a boon for healthcare, but something equally small, portable, and safe is going to have to power those sensors. Researchers from the University of Illinois may have an answer: batteries that slowly decompose in the body. Using magnesium and either iron, tungsten, or molybdenum, the researchers were able to build a small battery that delivered a constant output for at least 24 hours. Operating voltage varies by element, ranging from approximately 0.45V to 0.75V, and by stacking cells in series, the researchers say that they were able to create a battery strong enough to power a conventional LED.
