About This Product
■Summary
Cerawave® is a piezoelectric element made by printing conductors on piezoelectric green sheets, laminating and firing them. Voltage control generates vibrations due to minute changes in expansion and contraction, making it suitable for control mechanisms that require high precision and high-speed response. Cerawave® is available in three types of materials (NP-6, NP-7, and NP-T1).
NP-6 A hard material with a high mechanical quality factor Qm value, suitable for applications that utilize ultrasonic vibrations generated at resonant frequencies. It has high energy conversion efficiency and generates little heat when operating at the resonant frequency. A small-sized, high-torque actuator can be realized.
NP-7 is a soft material with a Qm value of 100 or less, a high piezoelectric strain constant d value, and a high dielectric constant ε, making it suitable for applications such as actuators, sensors, and speakers that take advantage of high displacement.
NP-T1 has properties intermediate between NP-6 and NP-7, and is characterized by a high phase transition temperature (Curie temperature Tc). It is resistant to polarization loss due to the thermal history of component mounting, making it suitable for use in high temperature ranges. It is also possible to operate by applying an electric field opposite to the polarization direction, making it ideal when you want bimorph-like behavior.
Cerawave® is a registered trademark of our piezoelectric element.
Features
■Thin laminate products possible
The advantages of using a stacked type include ``larger displacement,'' ``faster response speed,'' ``higher resolution,'' and ``lower input voltage.''
■Customized products made from three types of piezoelectric materials to suit your needs
There are no standard products for Cerawave®, and all products are custom made. Customization of various shapes is possible. We propose materials that meet customer requirements such as low loss, large displacement, and expanded operating temperature range.
