1. A therapeutic device comprising:
- a therapy electrode comprising;
a substrate;
a conductive layer disposed on a lower surface of the substrate and configured to deliver a therapy to a subject; and
an acoustic sensor disposed within the therapy electrode and mechanically coupled to the conductive layer, the acoustic sensor configured to acoustically couple to a body of a subject to which the therapy electrode is applied, the acoustic sensor comprisinga multi-channel accelerometer,wherein a first channel of the multi-channel accelerometer is configured to monitor sounds produced by a heart of the subject, anda second channel of the multi-channel accelerometer is configured to monitor at least one additional parameter associated with a state of the subject, the at least one additional parameter including one or more of a parameter associated with respiration of the subject, gastrointestinal sounds of the subject, snoring of the subject, body position of the subject, and body movement of the subject.
