A Study on Segmentation of Distributed Piezoelectric Sensors and Actuators: Part 1. Theoretical Analysis

Abstract

Active structures possessing self sensation and action/reaction capabilities provide new design alternatives for new structural systems. In this paper, distributed piezoelectric layers coupled with elastic continua are used as distributed sensors and actuators for structural monitoring and control. It was noted that a fully (symmetrically) distributed piezoelectric sensor/actuator could lead to minimum, or zero, sensing/control effects for anti-symmetrical modes of structures, especially with symmetrical boundary conditions. One method to improve the performance is to segment the symmetrically distributed sensor/ actuator layers into a number of collocated sub-segments. However, the effects of segmented distributed sensors/actuators are not quantitatively investigated. (Author)
