Smart materials and structures.
A smart structure is a system containing multifunctional parts that can perform sensing, control, and actuation; it is a primitive analogue of a biological body. Smart materials are used to construct these smart structures, which can perform both sensing and actuation functions. The ‘‘I.Q.’’ of smart materials is measured in terms of their ‘‘responsiveness’’ to environmental stimuli and their ‘...
متن کاملBiologically inspired ‘smart’ materials
Inspiration from nature and its translation to designing the next generation of biomedical devices have received immense attention recently. Biologically inspired materials utilise billions of years of evolution to generate diverse properties that would otherwise be difficult to achieve. These materials have the potential to address many limitations associated with more traditional materials. T...
متن کاملSmart materials in dentistry.
Most dental materials are designed to have a relatively 'neutral' existence in the mouth. It is considered that if they are 'passive' and do not react with the oral environment they will be more stable and have a greater durability. At the same time, it is hoped that our materials will be well accepted and will cause neither harm nor injury. This is an entirely negative approach to material tol...
متن کاملSmart Materials, Precision Sensors/Actuators,Smart Structures, and Structronic Systems
Many electroactive functional materials have been used in smalland microscale transducers and precision mechatronic control systems for years. It was not until the mid-1980s that scientists started integrating electroactive materials with large-scale structures as in situ sensors and/or actuators, thus introducing the concept of smart materials, smart structures, and structronic systems. This p...
متن کاملMaterials That Sense and Repond: An Introduction to Smart Materials
INTRODUCTION Each of us reacts to the world around and within us by sensing and actuating. When our hand is in contact with a hot object, we sense the heat, our brain sends a command, and our arm muscles actuate our hand away from the object. Similarly, because of internal sensing, we will tend to favor the burned hand until it has healed. As technology progresses, it becomes reasonable to ask,...
