A performance monitoring system includes a pitching mound, one or more processors, and a memory. The pitching mound includes a piezoelectric film associated with a pitching rubber, one or more rubber layers covering the piezoelectric film, a transmitter electrically coupled to the piezoelectric film, and a power source powering an amplifier associated with the piezoelectric film. The piezoelectric film generates electrical signals in response to pressure exerted on the pitching rubber. The processors are configured to receive the electrical signals generated by the piezoelectric film and transmitted by the transmitter. The processor is configured to analyze the received electrical signals based on training data using machine learning algorithms to determine at least one performance characteristic of the pitcher. The processors are configured to display on a display device the determined at least one performance characteristic in real-time.

A multilayered structure is provided. The multilayered structure may include a silicon substrate and a film of gadolinium oxide disposed on the silicon substrate. The top surface of the silicon substrate may have silicon orientated in the 100 direction (Si(100)) and the gadolinium oxide disposed thereon may have an orientation in the 100 direction (GdO(100)).
