Self-folding kirigami at the microscale

Three-dimensional shells can be obtained from the spontaneous self-folding of two-dimensional 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. In principle, different nets can fold into the same three-dimensional structure. However, recent experiments and numerical simulations show that the stochastic nature of folding might lead to misfolding and so, the probability for a given net to fold into the desired structure (yield) depends strongly on the topology of the net and experimental conditions. Here we discuss ongoing efforts to establish a relation between the structural features of the nets and their folding time and probability of misfolding.
