PIEZO FIBER COMPOSITE STRUCTURE AND DEVICE USING THEREOF

摘要

The present invention relates to a piezo-fiber composite structure and, more specifically, to a structure for adding flexible properties to a piezo-fiber composite structure. Also, the present invention relates to a device using the piezo-fiber composite structure. According to an embodiment of the present invention, the piezo-fiber composite structure comprises multiple piezoelectric ceramic rods in which multiple piezoelectric ceramics are connected while having metal layers interposed therebetween in a length direction, wherein the piezoelectric ceramic rods are arranged in parallel to each other so that the piezoelectric ceramics and the metal layers are respectively arranged in parallel along a direction vertical to the length direction, and adhesives are arranged among the piezoelectric ceramic rods arranged in parallel so that the piezoelectric ceramic rods can be connected to one another.
