Shape-Shifting Lattice Responds to Temperature

Oct-05-19 A shape-shifting lattice that will alter form in response to temperature could have applications ranging from smart fabrics to robotics.

The complex, temperature-triggered structure was created by a team from Harvard University using a bilayer, mulitimaterial lattice design. To allow for complex shapes, the team turned to materials with different thermal responses that were printed in predetermined configurations, allowing for control of each lattice rib. In a demonstration, the team printed an antenna able to shift shape to change resonant frequencies, as well as a flat form that morphed into the shape of mathematician Carl Friederich Gauss.

According to co-first author, Wim M. van Rees, “The open cells of the curved lattice give it the ability to grow or shrink a lot, even if the material itself undergoes limited extension.”
