Abstract

Security control becomes most important in the complicated IT society and human life, therefore, the combination between the multi-functional sensor/actuator devices and telecommunication module will undoubtedly extend toward more wide application fields of intelligent/smart materials and structures. Our recent developments of new functional solid state senor/actuator, SMA and magnetostrictive alloy materials by controlling crystalline microstructure by rapid-solidification technique are introduced. Next, smart composite system with active and embedded nondestructive evaluation module etc. are introduced including in foreign countries. Wireless sensing and active sensing combined with IT (information technology) seem promising and valuable subject in the very near future for smarter design concept of machinery and structures.
