- Experimental realization of stochastic folding Self-folding kirigami has been proposed to obtain 3D structures from 2D templates. At the macroscale, self-folding is usually driven by stress relaxation, with a unique folding path and structure [1]. In recent years, there has been an increasing number of methodologies to obtain folded structures at the microscale stochastically, e.g. DNA origami [2] and emulsion droplet self-folding [3]. At the microscale, due to the presence of thermal fluctuations, the folding process is stochastic, and the obtained structures and folding paths depend on the initial template and experimental conditions [4]. Stochastic folding has advantages as it is usually simpler, reversible, and requires minimal external control, thus easier to scale up. Previous studies are mainly numerical as controlled experiments at the microscale are difficult. In this work, we are developing an experimental setup to study self-folding at the macroscale driven by different sources of stochastic forces inspired by similar systems designed to study self-assembly processes. The results obtained are compared with results at the microscale and with computational simulations performed in our research group. References[1] E.A. Peraza Hernandez, D.J. Hartl, D.C.
