Wearable cardiac defibrillator system sensing being touched by bystander

A wearable cardiac defibrillator (WCD) system, comprising:

• a support structure configured to be worn by a patient;
• an energy storage module configured to be coupled to the support structure and to store an electrical charge;
• a discharge circuit configured to be coupled to the energy storage module and configured to discharge the electrical charge through the patient;
• and
• a capacitance meter coupled to the support structure and configured to detect whether or not the patient is being touched by a person other than the patient while the support structure is worn by the patient, and
• in which the discharge circuit is prevented from discharging the electrical charge through the patient, while the capacitance meter detects that the patient is being touched by the person.
