Phase transforming cellular materials

A phase transformational cellular material, comprising:

• a plurality of bistable cells, each respective bistable cell operationally connected to at least one other respective bistable cell;
• wherein the plurality of bistable cells is piezoresponsive;
• wherein each bistable cell enjoys a first stable phase and a second stable phase;
• wherein the first stable phase is a first geometric configuration;
• wherein the second stable phase is a second geometric configuration different from the first geometric configuration;
• wherein a thermal energy transaction is required to shift each respective cell between the second stable phases and the first stable phase.
