Abstract: Various systems and methods for managing disposable sensors and electrode gel are disclosed. According to an embodiment, a sensor assembly configured to be attached to a patient includes one or more electrode modules. Each of the one or more electrode modules includes an electrode, electrode gel disposed in a storage location on the electrode module, wherein electrode gel is not in contact with the electrode in the storage location, and a deformable cap configured to move the electrode gel from the storage location into contact with the electrode in response to a deformation of the deformable cap.

Abstract: An electrode configured to adhere to a patient's skin to conduct electrical potentials therefrom includes a substrate, a skin adhesive configured to adhere the electrode to a patient's skin, and a conductor plate mounted on the substrate. A conductive gel is configured to contact the patient's skin and to conduct electrical potentials from the patient's skin to the conductor plate when the electrode is adhered to the patient's skin. A removable separator is positioned between the conductive gel and the conductor plate, wherein the removable separator is configured to be removed prior to operating the electrode to conduct electrical potentials.
