APC International Ltd designs and manufactures piezoelectric products including various piezoelectric ceramics and actuator devices used in aerospace, automotive, medical, defense, consumer products, engineering and design industrial applications.

TRS Technologies manufacture piezoelectric actuators including 33-mode models, 31-mode models and 15 mode piezoelectric actuators. The three simplest piezoelectric actuator designs are the cylindrical actuator, the bimorph (and unimorph) actuator, and the multilayer actuator. Cylindrical actuators operate in 31-mode with the electric field applied across the cylinder wall to obtain an elongation of the length of cylinder.

Micemechatronics Inc. is a manufacturer of a variety of piezoelectric actuators. Types include NOLIAC-Ceramic multilayer actuators, stacked ceramic multilayer actuators, actuator rings, stacked ceramic multilayer actuator rings and rectangular area multilayer actuators in a variety of sizes.
