Design and feedback control of self-folding untethered miniature origami robots
… robot. The idea of magnetically-controlled, self-folding origami robots has been proposed to enable universal robot construction on this scale. This thesis continues the investigation into miniature magnetic origami robots by exploring specifically the design and control of such robots. We …

Sticker controller and sticker programming for smart sheets (self-folding sheets)
This thesis describes a self-folding sheet that is capable of origami-style autonomous folding. We describe the hardware device we designed and fabricated. This device, called a self-folding sheet, is a sheet with a box-pleat pattern and an integrated electronic substrate and actuators. The sheet …

Self-folding bilayers: Mechanistic design principles for programmable and on-demand shape reconfiguration
… toward a rational understanding of bilayer self-folding behavior. The hinge-less bilayer stars morphed into axisymmetric gripper-like configurations at high mismatch strains. Self-folded grippers that are widely used in micro/ nano-manipulation have previously been fabricated from patterned …

Development of self-folding origami sensors through the use of resistance, capacitance, and inductance
… need for printable sensors through the use of self-folding, conductive origami. Using Miyashita's technique for self-folding origami through global heat application, a several sensors were designed and fabricated. A variable resistor design can detect compression via shorting between tiles …

Advanced in situ hydrogel assembly for guiding molecular release
… materials in a hydrogel. First, I demonstrated a self-folding, multi-walled poly(ethylene glycol) diacrylate (PEGDA) hydrogel tube. This tubular structure was obtained by in situ self-folding of a bi-layered PEGDA hydrogel patch constructed with gels of significantly different rigidity and …

Effects and dynamics of the UNC-45B molecular chaperone
… work. This complex protein is incapable of self-folding and assembly. Instead, the molecular chaperones work in a precise network to allow a nascent polypeptide to be protected from aggregation and folded to the precisely native product. The assembly of this myosin into a thick filament can …

3D-printing form and function
… section. A stimulus-free strategy to 3D-print self-folding composites at room temperature is presented in the second part of this thesis. Specifically, the focus is on printing flat electrical composites that fold into pre-programmed shapes after printing using residual stress defined in …

On the foldability of rigid origami
… programmable matter, origami (the art of paper folding) and kirigami (paper folding with cutting) are especially appealing, as they are effective tools for transforming simple two-dimensional materials into complex three-dimensional structures. Rigid origami is the underpinning kinematics and …

Remote-Controlled Self-Assembly of Three-Dimensional Micro Structures for Ultra-Sensitive Sensors and Three-Dimensional Metamaterials
Self-assembly has been widely used to fabricate micro-scale three-dimensional (3D) structures for various applications like sensors, drug delivery systems, and advanced robotics (e.g., micro-actuators, micro-machines). Self-assembly is always driven by external sources (e.g., heat, solvent, pH), …

Solid-liquid interactions in microscale structures and devices
… in two distinct applications: capillary driven self-assembly of thin foils into 3D structures, and droplet wetting of hydrophobic micropatterned surfaces. The phenomenon of self-assembly of complex structures is common in biological systems. Examples include self-assembly of proteins into …
