A wearable defibrillator system includes a support structure with one or more electrodes in an unbiased state. A monitoring device monitors, for the long term, a parameter of the person that is not the person's ECG; rather, the monitored parameter can be the person's motion, a physiological parameter, or both. When a value of the monitored parameter reaches a threshold, such as when the person is having an actionable episode, the electrode becomes mechanically biased against the person's body, for making good electrical contact. Then, if necessary, the person can be given electrical therapy, such as defibrillation. As such, the electrodes of the wearable defibrillator system can be worn loosely for the long term, without making good electrical contact. This can reduce the person's aversion to wearing the defibrillation system.
