Abstract

Systems, methods, and devices having improved conformal properties for biomedical signal measurement are disclosed. A device can have a first polymer substrate coupled to a conductive layer forming a conductive trace electrically coupled to a conductive pad exposed via an opening. The device can have a second polymer substrate forming a first cavity between the first polymer substrate and the second polymer substrate. The device can have a first inlet portion that receives a fluid that expands the first cavity causing the device to conform to an anatomical structure. The structure can be an atrium, such as the left atrium, of the heart of a patient. The device can conform to the walls of the tissue structure, and the conductive pad exposed via the opening can detect a signal from the wall of the tissue structure. The signal can be provided to an external measurement device for processing.
