1. A method of using a wearable device, the wearable device comprising a first disposable component and a reusable component, the first disposable component comprising a patient engagement substrate comprising adhesive and an electrode on a bottom side, a disposable component electrical connector, and a disposable component mechanical connector separate from the disposable component electrical connector, the reusable component comprising a plurality of sealed housings mechanically and electrically coupled to the disposable component, a reusable component mechanical connector adapted to removably connect to the disposable component mechanical connector to provide a load-bearing mechanical attachment between a bottom side of the reusable component and a top side of the disposable component such that the disposable component is able to mechanically support and removably retain the weight of the reusable component on a patient at least partially through the mechanical connector, and a reusable component electrical connector separate from the reusable component mechanical connector and adapted to removably connect to the disposable component electrical connector, each of the plurality of housings containing one or more of a capacitor, batteries, or a controller, wherein the disposable component mechanical connector and the reusable component mechanical connector are configured to allow the reusable component and the disposable component to move relative to one another while still maintaining a mechanical connection, the method comprising:
adhering the wearable device to a skin surface portion of a patient for a first time period;
monitoring patient ECG signals with the controller and the electrode during the first time period;
removing the wearable device from the skin surface portion of the patient at the end of the first time period;
mechanically and electrically disconnecting the disposable component from the reusable component;
mechanically and electrically connecting to the reusable component a second disposable component comprising a patient engagement substrate comprising adhesive and electrodes on a bottom side;
applying the second disposable component to a skin portion of the patient; and
monitoring patient ECG signals using the controller and the electrode of the second disposable component.
