In order to solve the problem of limited driving speed of piezoelectric actuators when the piezoelectric components are small and the driving frequency is low. This paper proposes a bi-directional piezoelectric stick-slip actuator. which mainly utilizes the combination of flexible drive foot and lever amplification mechanism to realize the displacement amplification function. thus imp... https://www.missouriquiltcoes.shop/product-category/baby-quilt-patterns/
