An ultrasonic monitor implemented on a PCB includes a gel pad comprised of a gel layer and a membrane layer. Ultrasonic signals are transmitted between the ultrasonic monitor and a living subject through the gel pad. An air gap is formed in the PCB underneath transducer elements to provide for more efficient signal transmission. These features provide for a low power, low cost, more efficient ultrasonic monitor. The entire ultrasonic monitor may be encapsulated in plastic, a gel, or both to provide water resistant properties.
