Biologically 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 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 کاملElectroactive Smart Materials: New Challenges for Control
In this paper, the main objective is to provide an overview of a new class of research problems for the area which is broadly termed smart structures control. To this end, we describe electroactive smart materials and focus on control issues which naturally arise. Such materials, typically nano and micro-polymers, have mechanical properties controlled by an electric field. Unlike existing appro...
متن کاملHydrogels: Smart Materials for Drug Delivery
The limitations associated with the conventional therapeutics have intended the use of controlled drug delivery systems. In recent years, the hydrogel technology has been an integral part of human health care. The pharmaceutical industry has been developing hydrogel based drug delivery system in an advanced manner by tuning the structure, shape and surface modifications of the biopolymers. The ...
