According to foreign media reports, researchers at Carnegie Mellon University in the United States recently developed a biodegradable battery. The battery can be used to manufacture a controlled release device that is swallowed by the body like a pill and can supply controlled release medication dispensers or monitoring devices with "unprecedented" accuracy and safety. A swallowable "pill" battery already exists, but this miniature battery usually contains poisonous and harmful ingredients. The battery developed by the research team led by Christopher Bettinger, associate professor of materials science and biomedical engineering at Carnegie Mellon University, uses melanin, which the human body has long been accustomed to. The melanin present in human skin, hair and eyes is non-toxic and environmentally friendly. The researchers said that melanin can absorb ultraviolet light to inhibit free radical activity in the body, while binding and unbinding metal ions. During the test phase, the melanin battery can continuously supply power to the swallowable medical device for 20 hours.
