Curved Piezoelectric Actuators for Stretching Optical Fibers
Curved actuators produce greater displacements than do flat actuators.
Assemblies containing curved piezoceramic fiber composite actuators have been invented as means of stretching optical fibers by amounts that depend on applied drive voltages. Piezoceramic fiber composite actuators are conventionally manufactured as sheets or ribbons that are flat and flexible, but can be made curved to obtain ...

Cylindrical Piezoelectric Fiber Composite Actuators
Cylindrical actuators offer advantages over flat flexible actuators.
The use of piezoelectric devices has become widespread since Pierre and Jacques Curie discovered the piezoelectric effect in 1880. Examples of current applications of piezoelectric devices include ultrasonic transducers, micropositioning devices, buzzers, strain sensors, and clocks. The invention of ...
