Abstract
An ultrasonic monitoring device includes a substrate, a plurality of ultrasonic transducer elements, a computer readable memory medium, a microprocessor, and a power source. The ultrasonic transducer elements are coupled to the substrate. Each ultrasonic transducer element is separately configured to transmit a signal to a target area of a mammal and to receive an echo return signal from the target area. The computer readable memory medium includes program instructions. The microprocessor is coupled to the ultrasonic transducer elements and to the computer readable memory medium for executing the program instructions to determine a physiological parameter of the mammal based on a combined analysis of the echo return signals received by the ultrasonic transducer elements. The power source is coupled to at least one of the ultrasonic transducer elements, the computer readable memory medium, or the microprocessor for supplying electrical energy.
