Precision Pyroelectricity: LiTaO3's Impact in Motion Sensors
Witness the impact of LiTaO3's pyroelectric effect in the realm of motion sensors, where precision matters most. Our ultra-thin LiTaO3 wafers, at a wafer-level thickness of 20um and diameters reaching 4 inches, play a transformative role in enhancing the accuracy of motion-sensing applications. The inherent pyroelectric effect responds dynamically to temperature changes, allowing for meticulous detection in security systems and automation technologies. LiTaO3's thinness is not just a feature; it's the key to unlocking unparalleled precision in motion sensor applications.
