Tactile Perception through Fluid-Solid Interaction
Arman Goshtasbi, Minke Berghuis, Aida Parvaresh +3
Soft tactile sensors elevate robotic touch through enhanced flexibility and adaptability, yet most existing designs depend on embedded electronics that are susceptible to interfere…
Giving life to robotic skins
Ahmad Rafsanjani, Fergal B. Coulter, André R. Studart
The skin of humanoid robots often lacks human tactility and the inherent self-repair capability of biological tissues. Recently, researchers have grown a living, self-healing skin…
Kirigami-inspired inflatables with programmable shapes
Lishuai Jin, Antonio Elia Forte, Bolei Deng +2
Kirigami, the Japanese art of paper cutting, has recently enabled the design of stretchable mechanical metamaterials that can be easily realized by embedding arrays of periodic cut…
Programming Soft Robots with Flexible Mechanical Metamaterials
Ahmad Rafsanjani, Katia Bertoldi, André R. Studart
The complex behavior of highly deformable mechanical metamaterials can substantially enhance the performance of soft robots.
Propagation of pop ups in kirigami shells
Ahmad Rafsanjani, Lishuai Jin, Bolei Deng +1
Kirigami-inspired metamaterials are attracting increasing interest because of their ability to achieve extremely large strains and shape changes via out-of-plane buckling. While in…
Hydro-Responsive Curling of the Resurrection Plant Selaginella lepidophylla
Ahmad Rafsanjani, Véronique Brulé, Tamara L. Western +1
The spirally arranged stems of the spikemoss Selaginella lepidophylla, an ancient resurrection plant, compactly curl into a nest-ball shape upon dehydration. Due to its spiral phyl…
Buckling-Induced Kirigami
Ahmad Rafsanjani, Katia Bertoldi
We investigate the mechanical response of thin sheets perforated with a square array of mutually orthogonal cuts, which leaves a network of squares connected by small ligaments. Ou…
Bistable Auxetic Mechanical Metamaterials Inspired by Ancient Geometric Motifs
Ahmad Rafsanjani, Damiano Pasini
Auxetic materials become thicker rather than thinner when stretched, exhibiting an unusual negative Poisson's ratio well suited for designing shape transforming metamaterials. Curr…
Snapping Mechanical Metamaterials under Tension
Ahmad Rafsanjani, Abdolhamid Akbarzadeh, Damiano Pasini
We present a monolithic mechanical metamaterial comprising a periodic arrangement of snapping units with tunable tensile behavior. Under tension, the metamaterial undergoes a large…
The role of water in the behavior of wood
Dominique Derome, Ahmad Rafsanjani, Stefan Hering +7
Wood, due to its biological origin, has the capacity to interact with water. Sorption/desorption of moisture is accompanied with swelling/shrinkage and softening/hardening of its s…
Computational up-scaling of anisotropic swelling and mechanical behavior of hierarchical cellular material
Ahmad Rafsanjani, Dominique Derome, Falk K. Wittel +1
The hygro-mechanical behavior of a hierarchical cellular material, i.e. growth rings of softwood is investigated using a two-scale micro-mechanics model based on a computational ho…
