1. A wearable external defibrillator comprising:
a first patient engagement substrate comprising an adhesive, a first defibrillator electrode pad, a first fluid transport element configured to transport fluid away from the skin to allow the wearable external defibrillator to be worn continuously, and a first vapor permeable layer;
a second patient engagement substrate comprising a second defibrillator electrode pad, a second adhesive, a second fluid transport element configured to transport fluid away from the skin to allow the wearable external defibrillator to be worn continuously, and a second vapor permeable layer;
an energy source;
one or more capacitors in electrical communication with the energy source and the first defibrillator electrode pad and the second defibrillator electrode pad;
a controller configured to detect a cardiac signal with two or more sensing electrodes and to charge the one or more capacitors with the energy source followed by discharging the one or more capacitors to deliver a therapeutic shock through the first defibrillator electrode pad and the second defibrillator electrode pad to the patient while the first and second patient engagement substrates are engaged with the patient;
a plurality of housings supported by the first patient engagement substrate, the plurality of housings each configured to reversibly receive and support one or more of the energy source, the one or more capacitors, and the controller; and
a plurality of electrical connectors, each configured to reversibly electrically engage with one or more of the energy source, the one or more capacitors, and the controller.
