Smart Material - Shape Memory Alloy

CAN a material possess intelligence? The answer depends on what one means by intelligence. One tends to associate intelligence with what a human brain can do: memory, thinking, problem solving, learning, creativity, etc. A artificial computer can do some of these tasks, but in terms of more sophisticated aspects of intelligence, it is no match even to a modest human brain. The recognition of these ultimate limits has inspired many scientists to study biological system as a model for developing intelligent or smart systems. Several smart systems (or structures) are in various stages of development for civil, military and various biological applications. Air forces require smart planes that can continuously change the wing's shape to achieve supersonic speed and evade radar screen. Diabetics need medical systems to sense sugar levels and deliver insulin. Architects are designing smart buildings with self-adjusting windows and self-cleaning materials we have made a comparative study between shape memory alloy materials and other generally used materials or alloys.
