Smart materials: shape memory alloys and shape memory polymers

Shape memory alloys (SMA) and shape memory polymers (SMP) remember their original shape, even after being significantly deformed, returning to their original shape in response to a stimulus. This resource explores the technology behind SMA's and SMP's, the properties that they bring to engineered products and examples of how they are used. Topics that are covered include Nitinol, self healing polymer, memory foam.
