Piezoelectric Devices

NIKKO’s piezoelectric devices are ideal for piezoelectric actuators that generate voltage-controlled micro-vibrations for high-precision positioning controllers.

Features

NIKKO’s piezoelectric devices are ideal for piezoelectric actuators that generate voltage-controlled micro-vibrations for high-precision positioning controllers.
Thin Multilayer Devices – Features of the multilayer structure are

1) Larger displacement amount;
2) Fast response time;
3) Lower input voltage.

NIKKO’s piezoelectric devices are custom designed for the application using 3 types of piezoelectric material and can accommodate various shapes and dimensions. All products are custom designed, no standard products.
