摘要

Coriolis effect, regarded as one of the universal physical law, describes the phenomenon that an arbitrary object will deflect left relative to the original speed when the object is laid on a reference frame with clockwise rotation, and vice versa. In this Letter, we designed a specialized piezoelectric metamaterial which is consist of a piezoelectric sensing element, an elastic rubber, and a mass element by using the finite element method (FEM). The FEM results suggested that the deflection behavior in this type of piezoelectric metamaterial, could strictly break the Coriolis effect and a negative Coriolis effect was observed. The exploration of negative Coriolis effect in piezoelectric metamaterial would provide theoretical guideline for the further design of ultrasensitive gyroscopes. (C) 2019 Published by Elsevier B.V.
