Piezoelectric Wafers for Reducing the Structure Vibrations,vin,1918), but it was only in the early seventies that the use of polyvinil-di-fluor (PVDF in brief) spawned a generalized use of this effect in mechanics. One of the most often mentioned reference is that of H. Kawai, 1969.

Optimal Actuator Placement in Adaptive Precision Trusses,n be achieved by the use of highly sensitive actuators, such as the JPL Active Member (Fanson et al., 1989, Anderson et al., 1990). These actuators are attached at their vertices (i.e., end points) to the nodes of the precision truss structure and are capable of length extension/contraction.

Introduction to Smart Structures, force. Upon processing this signal received from the sensor, the control system then impresses an appropriate voltage upon the piezoelectric actuator that induces a counteractive deformation and damping into the beam. The beam’s oscillations are subsequently quickly diminished.

Distributed Transducer Design for Intelligent Structural Components,r the combined effects of such designs to cause the resulting structure to have slow responses and relatively long decay times which tend to undermine performance objectives and degrade system stability.
