A movement and sound monitor and stimulator which is particularly useful for preventing death in human infants from sudden infant death syndrome is disclosed. The movement and sound monitor and stimulator has a base member which may be a fluid-filled sensing pad for supporting the infant or other animate object which is being monitored and a transducer positioned for detecting movement or acoustic activity (e.g., heartbeat, breathing) of the object on the base member to provide an output signal in response to forces applied thereto which are generated by such movement. A circuit is connected to monitor the output signal from the transducer and activates a stimulator which is operable to provide movement to the base member to stimulate movement in the object when output from the transducer to the circuit corresponds to no movement from the object. The transducer may be a pressure transducer in fluid communication with the fluid interior of the sensing pad. In the alternative, a piezo-electric sheet operatively connected to a surface of the sensing pad to detect such movement as well as movement cessation. The circuit may also be connected to an alarm which can provide an audible or visual indication to third parties when there is no movement from the object.
