SENSOR USING SHAPE MEMORY ALLOY AND INTELLIGENT TYPE COMPOSITE MATERIAL

摘要

PURPOSE: A sensor using a shape memory alloy and intelligent type composite material are provided to be employed for various appliances and various fields requiring fine variation by using one device replacing at least two devices in order to perform measurement and driving at the same time. CONSTITUTION: A sensor using shape memory alloy and intelligent type composite material are capable of calculating variation of an internal resistance value. Although the shape memory alloy is changed by external physical force, the shape memory alloy has an original shape above a predetermined temperature. After the shape memory alloy is changed into a required shape, the required shape is achieved through heating treatment. The shape memory alloy has a plate shape including a strain gauge pattern(200). On the intelligent type composite material(100) a pattern having a strain gauge function on the shape memory alloy is formed. A plate of the shape memory alloy includes nitinol alloy.
