A living-body contact electrode used primarily in a garment for measuring living-body information, which is comfortable to wear, even during exercise, without rubbing between the electrode and the skin while acquiring a stable electrical signal in a dry state and a wet state. A living-body contact electrode can acquire a living-body electrical signal with decreased electrical noises by suppressing the displacement of the electrode without impairing feeling and feel of wearing by suppressing the skin irritation. This is achieved by limiting the coefficient of static friction of the surface of the electrode with respect to the skin, by decreasing the frictional coefficient of an electrical wiring part to be equal to or less than a predetermined value, and by combining the electrical wiring part with the electrode.

A probe device provides an enhanced bioelectric and spring-loaded sensing tip with an integrated force sensor. The probe device measures the bioelectric conductance value from a patient for therapeutic and/or diagnostic purpose using the spring-loaded sensing tip. In addition, the probe device measures the force applied by the spring-loaded sensing tip against the patient using the integrated force sensor. Using feedback from the force sensor and the bioconductive data of the patient, the force applied at the spring-loaded sensing tip may be adjusted to obtain improved results.

In embodiments, a wearable cardioverter defibrillator (WCD) system includes a support structure for wearing by an ambulatory patient. When worn, the support structure maintains electrodes on the patient's body. Different pairs of these electrodes define different channels, and different patient ECG signals can be sensed from the channels. The ECG signals can be analyzed to determine which one is the best to use, for the WCD system to make a shock/no shock decision. The analysis can be according to widths of the QRS complexes, consistency of the QRS complexes, or heart rate agreement statistics.
