It is a functional ceramic with a direct piezoelectric effect that converts mechanical energy into electrical energy and a reverse piezoelectric effect that converts electrical energy into mechanical energy. It is a material with very high mutual conversion efficiency.
A dielectric material is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization.

Since our ceramic-glass composite electrode emits large amount of secondary electron and has large number of polarization in electric field, it is possible to increase the brightness of the lamp by moving more electrons and ions.

When the highly strong ultrasonic energy is collected to focus, strong heat (65 ~ 100 ℃) is generated and it is called high intensity focused ultrasound(Hifu). When about a hundred thousand times stronger ultrasonic wave is focused in one point than the intensity of the ultrasound used to diagnose, the heat is generated in the focused area, which is similar that collecting the solar light to focus the heat using a convex lens.
