While nonlinear-elastic materials demonstrate potential in enhancing the performance of compliant mechanisms, their behavior still needs to be captured in a generalized mechanical model. To inform new designs and functionality of compliant mechanisms, a better understanding of nonlinear-elastic materials is necessary and, in particular, their...

Nanopores are narrow channels in cell membranes that control the passage of small molecules. In recent years, they have been repurposed for diverse applications, including single molecule sensing and drug delivery. Due to the small diameters of conventional protein-based, current research efforts are directed to designing nanopores from other...

The use of origami-based mechanisms in the engineering field is growing as their advantages are better understood. Origami-based mechanisms have the advantage of being lightweight, compact, and their ability to transform from a flat sheet into complex three-dimensional structures makes them a source of inspiration to meet design challenges. A...

In recent times, there has been a growing interest in spending extended amounts of time in outer space. To enable these endeavors, living and storage spaces will have to be much larger than current technologies can transport and set up in space. An interesting solution to this problem is the usage of a deployable structure that occupies a small...

Compliant mechanisms are often used in precision mechanism design as a suspension for translational stages. Their light weight makes them efficient and they do not suffer from friction or backlash. They transmit and transform a finite motion along their degrees of freedom via elastic deformation and provide high stiffness along their degrees of...

This project explores the potential of a material system based on SMAs that generates haptic feedback for Visually Impaired People (VIPs). Since VIPs rely more than others on tactile information, there is a need for more natural and unintrusive haptic devices as the commonly used electromechanical actuations are often perceived as intrusive and...

Origami-based mechanisms have emerged as a promising solution for developing locomotion systems. Its light-weight nature, scalability, and possibility for 2D monolithic manufacturing makes origami an attractive option for various applications, such as mobile robots and meta-surfaces. While various types of origami-based locomotion exist,...

Origami structures are a traditional Japanese art that have recently found their way into engineering applications due to their powerful capability to transform flat 2D structures into complex 3D structures along their creases. This has given a rise to their application as designer materials with unprecedented mechanical characteristics, also...

Microtubules are dynamic cytoskeletal filaments that can generate forces when polymerizing and depolymerizing. Proteins that follow growing or shortening microtubule ends and couple forces to cargo movement are important for a wide range of cellular processes. Quantifying these forces and the composition of protein complexes at dynamic...

The discovery of DNA origami nanotechnology has opened new opportunities in this field due to the versatility of the shapes and sizes that can be generated, the ease of modification and functionalization with molecular resolution, and its biocompatibility. Using Watson-Crick base pairing as the main driver in the self-assembly procedure, DNA...

Folding nanopatterned flat sheets into complex 3D structures enables the fabrication of meta-biomaterials that combine a rationally designed 3D architecture with nanoscale surface features. Self-folding is an attractive approach for realizing such materials. However, self-folded lattices are generally too compliant as there is an inherent...

Nanopores are versatile single-molecule sensors offering a simple label-free readout with great sensitivity. We recently introduced the nanopore electro-osmotic trap (NEOtrap) which can trap and sense single unmodified proteins for long times. The trapping is achieved by the electro-osmotic flow (EOF) generated from a DNA-origami sphere...

Miniaturizing mechanical tessellations with rigid origami behavior is difficult since rigid origami can only be approached in real mechanical systems. Rigid-origami means that the fold-lines have zero stiffness, and the facets have infinite stiffnes. However, zero stiffness and infinite stiffness can physically not be obtained. To approach the...

At first glance nanopores may appear simple, almost intuitive, to understand given that they are, quite literally, ‘just’ very small pores in a membrane. In fact, one may even wonder why at all we need trained scientists to study such seemingly simple entities. The short answer is that nanopores, as the word suggests, are nanoscale entities and,...

Knipscheer, Cassey (author)
Curved crease origami (CCO) is a newer, interesting field in origami mechanisms. The surfaces on CCO can be bent to initiate folding, thus allowing for the use of planar bending actuation. In this work, the use of more or less of the available actuation surface of CCO is explored. This is done by heating a bilayer material made of paper and...

Origami structures are found in mechanical technology more and more often. A less strict derivative of origami are Hinging Rigid Panel Structures, which are not bound to be developable from a single flat sheet of planar material. These Hinging Rigid Panel Structures can be applied to many fields of mechanical design, and moreover are interesting...

The goal of this thesis is to look into the possibilities of making origami neutrally stable. This is wanted because the inherent stiffness of origami mechanisms introduces unwanted artifacts such as a higher actuation force, and the mechanism not following the theoretical kinematics. By making an origami mechanism neutrally stable the inherent...

Without our musculoskeletal system, which consists of bones, joints, and muscles, we would not be able to live. Our bones are responsible for the protection of our organs, the support of our body, and they enable our mobility. Therefore, it is important to keep them healthy. This is done by cells who repair small cracks and fractures caused by...

It is relevant for various applications to seek a material that could be used for the active control of wave propagation. In this study, we explore tunablemetamaterials based on foldable origami sheets where the size of the bandgap can be tuned by the rigid folding along predefined crease lines. A combination of out-of-plane components and a...
