Smart Composites Using Shape Memory Alloy for Sensor and Actuator Application

摘要

The present invention is by measuring the amount of deformation of the shape memory alloy element and to transform the device into a desired amount of deformation relates to an intelligent Composite. ; is inserted into the device prepared as shown in Fig. 1 so that the shape memory alloy can be a strain gauge. The inserted shape memory alloy can be measured by measuring the amount of deformation such change is a change in the resistance of saenggimyeo unique shape memory alloy because the specific strain during the deformation element. ; In addition, since a voltage is applied to both ends of the shape memory alloy to control the shape memory deformation and thermal deformation of the Joule heat generated in the shape memory alloy may serve as a driving element. ; The present invention device has a feature that can be measured and the driving of the strain as one element on the other hand, to measure the amount of deformation and the drive by the conventional two or more elements.
