"WebKirigami technique, which is the Japanese art of paper cutting, turns inextensible sheets into ultra-stretchable structures through the opening up of the material [1] enabled by slits (figure1a). In a flow, kirigami sheets thus act as a poro-elastic surfaces : the structure deforms, opening pores which in turns affect fluid loading. " - Flow-induced deformation of kirigami sheets
