“Researchers at the University of Waterloo have developed a technology that enables multiple shape memories to be embedded in a single monolithic shape memory material. In addition, this technology can be implemented to locally modify pseudoelastic properties. This ‘multi-memory material’ locally transforms (changes shape) at specific, predetermined transition temperatures. Hence various different shapes can be memorised at discrete temperatures.” Read more and watch the video at
