Abstract

A stethoscope system may include an array of sensors, which may include pressure sensors. The array may be implemented in a wearable “patch” that is conformable to a patient's body. The stethoscope system may include a control system that is capable of receiving signals from the array of sensors. The signals may, for example, correspond to measurements from multiple pressure sensors of the array. The control system may be capable of combining signals from multiple pressure sensors to produce combined signals. The control system may be capable of filtering the combined signals to remove, at least in part, breathing signal components and to produce filtered signals. The control system may be capable of determining a correspondence between heart signal components of the filtered signals and corresponding heart valve activity.
