1. **Piezoelectric Transformer Showing a Reduced Input Impedance**: This invention involves a piezoelectric substrate that extends in a first direction, equipped with a first electrode structure. This structure excites an elastic wave that propagates through the substrate due to the piezoelectric transverse effect. In addition, a second electrode structure is implemented on the substrate to convert the elastic wave into an electric voltage, ensuring both the first and second electrode groups occupy designated areas on the substrate.
2. **Piezoelectric Transformer Producing an Output A.C. Voltage with Reduced Input Impedance**: This innovative transformer features a piezoelectric substrate with an input electrode structure on its upper major surface. This allows for the reception of an A.C. voltage that excites an elastic wave, which propagates through the substrate in a longitudinal direction. This design is complemented by an output electrode structure on the lower surface that converts the elastic wave back into A.C. voltage. Notably, both electrode structures have a periodic design that matches the wavelength of the elastic wave.
