According to the abstract* released by the U.S. Patent & Trademark Office: "Examples for monitoring impedance of a hydrogel in an electrode. The electrode is applied to a patient to measure impedance through the patient's body. Hydrogel is used to conduct electrical signals between the patient's body and sensing circuitry of the electrode. The impedance of the hydrogel can change over time as the electrode is being worn. When the electrode is appli...
