Responsive materials are materials which change in response to environmental stimuli. Examples include hydrogels or other polymer gels, photochromic or thermochromic materials,piezoelectric materials, light-emitting materials, and thermoelectric materials.
Responsive Material Applications
Responsive materials have applications that affect most of our everyday lives. Digital weight scales use piezoelectric strain gauges to determine weight. Transition (c) lenses use photochromic material to tint in response to UV light.
This powerpoint shows several examples of responsive "smart" materials.
By using materials which change shape or conformation upon environmental stimuli, self-cleaning surfaces can be created by using bio-inspired microfloret design which opens and closes to prevent biofouling.
