Structural designs based on the geometric arrangement of their building blocks have been utilized to develop advanced mechanical metamaterials. Here, the authors use the DNA origami method to realize a nanoscale metastructure exhibiting mechanical frustration, the mechanical counterpart of the well-known magnetic frustration, and show that this DNA metastructure can be precisely controlled to adopt either frustrated or non-frustrated mechanical states.
