Sponge-like electrodes inspired by sugar cubes could improve medical monitoring

To monitor heart rhythms and muscle function, doctors often attach electrodes to a patient’s skin, detecting the electrical signals that lie beneath. These impulses are vital to the early diagnosis and treatment of many disorders, but currently available electrodes have limited function or are expensive to manufacture. Researchers however, have now developed a low-cost, spongy version with improved signal detection that’s made with a surprising template — a sugar cube.
