NEC TOKIN

ʼs multilayer piezoelectric actuators are designed using unique

element structure technology and using ceramic materials with high

electrostrictive factors developed by NEC TOKIN.

Features

□ Special ceramics developed by NEC TOKIN are used in piezoelectric ceramic elements.

□ As compared with conventional actuator elements, NEC TOKINʼs multilayer piezoelectric actuators have

advantages as follows.

■ Advantages over electromagnetic actuators

⃝ Faster response

⃝ High resolution for positioning

⃝ Large generated force

⃝ Low power consumption

⃝ No electromagnetic noise

■ Advantages over bimorph piezoelectric actuators

⃝ High energy conversion efficiency（around 7 times the

energy conversion efficiency of the bimorph type

actuator

）, and low power consumption

⃝ Large generated force

⃝ Stable displacement, and reduced shift and creep phenomena

⃝ Response speed（more than 100 times the response

speed of the bimorph piezoelectric actuator

）

■ Advantages over stacked piezoelectric actuators

⃝ Compact size（less than 1/10 the specific volume of

the stacked piezoelectric actuator

）

⃝ Low drive voltage, and ease of use

⃝ Inexpensive
