This review gives a brief introduction to materials and techniques used for microfabrication. Rigid materials have typically been used to fabricate microstructures and systems. Elastomeric materials are becoming attractive, and may have advantages for certain types of applications. Photolithography is the most commonly used technique for the fabrication of structures for microelectronic circuits,...
“Nanostructured materials” are those having properties defined by features smaller than 100 nm. This class of materials is interesting for the reasons: i) They include most materials, since a broad range of properties—from fracture strength to electrical conductivity—depend on nanometer-scale features. ii) They may offer new properties: The conductivity and stiffness of buckytubes, and the broad range...
Locomoting soft robots typically walk or crawl slowly relative to their rigid counterparts. In order to execute agile behaviors such as jumping, rapid actuation modes are required. Here we present an untethered soft-bodied robot that uses a combination of pneumatic and explosive actuators to execute directional jumping maneuvers. This robot can autonomously jump up to 0.6 meters laterally with an...
A mid-infrared (mid-IR) label-free chemical sensor was developed using opto-nanofluidics consisting of a Si-liquid-Si slot-structure. A broadband mid-IR lightwave can be strongly confined within a nanofluidic capillary by utilizing the large refractive index contrast (Δn ∼ 2) between the liquid core waveguide and the Si cladding. Through an optical-field enhancement together with a direct interaction...
A mid-infrared sensor for label-free on-chip chemical detection was developed using an engineered nanofluidic channel consisting of a Si-liquid-Si slot-structure. A sensitivity with 75 times improvement was achieved compared to conventional evanescent-wave sensing. Mid-infrared spectroscopy is a detection technique commonly used for identifying biochemicals and tracing of toxic molecules, and is free...

This paper presents preliminary results for the design, development and evaluation of a hand rehabilitation glove fabricated using soft robotic technology. Soft actuators comprised of elastomeric materials with integrated channels that function as pneumatic networks (PneuNets), are designed and geometrically analyzed to produce bending motions that can safely conform with the human finger motion....
This paper describes a new method for fabricating highly stretchable and robust electrical circuits. The circuits consist of liquid metal (eutectic gallium indium alloy, EGaIn) enclosed in elastomeric microfluidic channels. In particular, a microfluidic hybrid structure made of two types of elastomers (polydimethylsiloxane (PDMS) and Ecoflex (type 0030, Reynolds Advanced Materials) with different...
We demonstrate the fabrication of plasmonic nanostructures (rings, split rings, and other structures) by a process involving molding by soft lithography, thin film deposition, and mechanical sectioning (nanoskiving). This unique process is highly parallelizable and allows for the fabrication of nanostructures of multiple materials in the same plane and very high aspect ratio structures. We characterize...
