Self-folding kirigami at the microscale

Three-dimensional shells can be obtained from the spontaneous self-folding of twodimensional templates of interconnected panels, called nets. To design self-folding,one first needs to identify what are the nets that fold into the desired structure. Inprinciple, different nets can fold into the same three-dimensional structure. However,recent experiments and numerical simulations show that the stochastic nature offolding might lead to misfolding and so, the probability for a given net to fold into thedesired structure (yield) depends strongly on the topology of the net and experimentalconditions. Here we discuss ongoing efforts to establish a relation between thestructural features of the nets and their folding time and probability of misfolding.
