1. A wearable non-invasive lung fluid monitoring system, comprising:
a wearable sensor configured to be positioned on a chest of a patient, the wearable sensor comprising:
a pad member constructed of a soft material or a flexible solid, the pad member having a first side and a second side, the first side forming at least a portion of a cavity extending from a first end of the pad member to a second end of the pad member, the second side including a low impedance acoustic material configured to maximize transmission of ultrasonic waves;
at least one transducer positioned within the cavity, the at least one transducer configured to generate at least one ultrasonic signal probing internal space within the chest of the patient and receive at least one reflected wave of the at least one ultrasonic signal;
at least one control system in electrical communication with the at least one transducer, and positioned adjacent to the at least one transducer, the at least one control system configured to drive voltages for the at least one transducers and receive data generated by the at least one transducer from the at least one reflected wave of the at least one ultrasonic signal;
at least one battery in electrical communication with the at least one control system, the at least one battery configured to provide electrical power for the control system and the at least one transducer; and,
an adhesive layer positioned on the second side of the pad member and configure to adhere to the chest of the patient; and,
at least one processor configured to determine at least one measurement estimate of fluid within the chest of the patient using acoustic impedance of the at least one ultrasonic signal and the at least one reflected wave of the ultrasonic signal and provide at least one indicator based on the at least one measurement estimate.
