GENEVA, SWITZERLAND: STMicroelectronics announced that it is commercializing its innovative piezoelectric MEMS technology.
This innovation combines the company's long-established leadership in high-volume MEMS design and manufacturing with the many new application opportunities offered by piezoelectric technology.
ST's TFP (Thin-Film Piezoelectric) MEMS technology is a foundational process platform that can be readily customized, allowing ST to work with customers around the world to jointly develop specific MEMS products, optimized for particular applications.
One of the first customers to take advantage of ST's TFP process is poLight, whose innovative TLens® (Tuneable Lens) uses a piezoelectric actuator to change the shape of a transparent polymer film, imitating the focussing function of the human eye. This makes it the ideal solution for camera auto-focus (AF) applications, which up till now have mostly relied on large, power-hungry, and expensive Voice Coil Motors (VCM).
