Ceramic Microactuators

What are Piezoceramics ?

Ceramic Microactuators

Features of Piezoceramics

  1. Low power consumption
  2. Compact dimensions
  3. High speed
  4. Powerful

Piezoceramics have broad applications in the automotive, electronics (e.g., televisions, PCs, digital cameras, mobile phones) and medical fields, among others. Based on high-performance materials and superior production techniques, NGK provides unique, high-quality piezoceramic actuators.

Technology

  • Materials

    Optimizing composition and microstructure to achieve high-performance piezoelectric materials
    Examples of materials and parameters:
    Soft PZT: piezoelectric coefficient d33 = 400~640 pm/V
    Hard PZT: mechanical quality factor Qm = 2200~2500

  • Manufacturing technologies

    NGK provides high-performance actuators via tape casting, screen printing, and tape lamination techniques. Using high-precision molding techniques, NGK also produces precise three-dimensional microscopic ceramic structures.
