Piezo actuator quotes2/28/2024 ![]() Elongation of a piezoelectric actuator is based only on deformation of the material and there is also no fatigue or aging involved. There are no moving parts and thus no friction or free play.Accelerations several thousand times higher than gravitational acceleration (G) can be attained As an example, the elongation response of a piezoelectric actuator can be limited only by the speed at which sound is propagated through ceramic materials. Extremely high response times of under 1 millisecond.High actuation forces can be attained without significant loss in precision, for instance loads higher than 10.000 Newtons can be positioned with micrometer accuracy.smallest changes in supply voltage are detected and converted into linear motion without skipping or stepping ![]() They have a theoretical unlimited resolution, often resolving to sub-nanometer values, i.e.Piezoelectric actuators have the following attributes: It is not uncommon for the most unexpected and unconventional solutions to be the key factor in the success of a certain product. The range of unconventional actuation techniques is much larger, continuous development taking place in the area, including other types of actuators based on electrostatics, electro and magnetorheology or magnetostriction principles. Shape memory actuators – found in robotic hands, actuating the artificial fingers.Artificial muscles – employed for mobility and manipulation features in humanoid robots.Electrochemical actuators – found in airbag expansion systems. ![]()
