Product Name:
|
Piezoelectric Ceramic Transducers for SAW(Surface acoustic wave) Touch Panel |
|
Description:
|
Thanks to the high curie temperature, low dielectric constant, and high anisotropic crystal structure of the lead titanate ceramic material (PT), we can successfully apply this material in the SAW(Surface acoustic wave) device for ultrasonic touch panel.
