55 interactive touch screen.Surface acoustic waves refer to those mechanical waves that propagate on the surface of the medium generated in the medium. This touch screen uses a single glass plate with a piezoelectric sensor attached to the corner of the screen. The interface controller can transmit high-frequency electronic pulses to a sensor that converts signals into SAW waves. Many mirror strips on the outer edge of the glass plate can reflect the sound waves to the active area of ??the glass. These receiving strips collect the sound waves and reflect them to sensors that can convert them into electronic signals.
