Thin Films, Mighty Applications: LiTaO3 in Biomedical Sensing
In the realm of biomedical sensing, LiTaO3 emerges as a game-changer, driven by its pyroelectric effect and our commitment to ultra-thin wafers. With a wafer-level thickness as fine as 20um and diameters extending up to 4 inches, these LiTaO3 wafers set a new standard in precision. The pyroelectric effect, when harnessed in biomedical sensors, ensures accurate temperature measurements vital in various medical applications. From patient monitoring to diagnostic tools, LiTaO3's thin film becomes the foundation for innovations that prioritize sensitivity and reliability in the biomedical field.
