SUMMARY
Piezoelectric actuators are limited to small displacements, typically in the micrometer range, making them unsuitable for applications requiring large deflections, such as bending a 10-meter cantilever beam by 1 meter. To achieve larger displacements, piezoelectric actuators can be integrated into lever systems or used in conjunction with stepper motors, which amplify their effect. However, the inherent strain of piezoelectric materials is small, and achieving significant displacement would necessitate impractically long actuators or large levers, which would compromise force output.
