Smart Materials

INTRODUCTION With  the event  of fabric  science, many new, high-quality and cost-efficient materials have  inherit  use in various field of engineering. The materials became multifunctional and required the optimization  of various  characterization and properties. With the last evolution, the concept has been driving towards composite materials and recently,  subsequent  evolutionary step is being contemplated with the concept of smart materials. WHAT ARE SMART MATERIALS? Smart Materials are those materials that posses  the power  to vary  their physical properties  during a  specific manner in response to its specific stimulus input. Here stimuli  might be  pressure, temperature, electric and magnetic fields, chemical and nuclear radiations too. These materials change their physical properties which  might be  shape, stiffness, viscosity, dumping etc. Materials achieve smartness which  is u...
