Abstract: The present invention provides a device and method for monitoring and detecting a fetal heartbeat that can be employed by ordinary people with minimal, if any, training, such as expectant mothers. The device can monitor and detect a fetal heartbeat with minimal positioning along the female body at the pregnant portion (the womb) as the device is configured to transmit and receive energy waves at wide angles. The device is economical and is preferably designed for domestic use, outside of the hospital or clinical setting. Specifically, the invention is based on a unique configuration of piezoelectric elements in cooperative configuration with a series of oscillators that is able to transmit and receive ultrasonic waves simultaneously The configuration allows for an optimal scanning range at an unlimited number of angles.
