Liquid crystals with a varying phase profile enable reconfigurable and intelligent devices to be designed, which are capable of manipulating incident electromagnetic fields in display, telecommunications as well wearable applications. The active control defects these is becoming more important, especially since the electrodes used manipulate them shrinking nanometer length scales. In this paper...

The development of neuron-microelectrode interfaces (neurochips) is highly desirable for the non-invasive recording of the cellular response to neuroactive drugs as well as the electrical stimulation of nervous tissue by implantable electrodes. A prerequisite for neuron-to-electrode signal transmission (NEST) is the formation of synapse-like contacts between the neuronal cell and the conductive...

Microfabricated interdigitated electrode array is a convenient form of electrode geometry for dielectrophoretic trapping of biological particles within micro-fluidic biochips. We have previously reported experimental results and finite element modeling of the holding forces for both positive and negative dielectrophoretic traps on microfabricated interdigitated electrodes within a microfluidic ...

Organic semiconductors have seen widespread application in thin-film devices, such as organic field-effect transistors (OFETs), whose performance is closely linked to the molecular-level microstructure and crystalline orientation. In actual OFETs, varies significantly based on local environment, for example, proximity of contact electrodes. This account highlights recent examples where microfoc...

Porous electrodes govern the electrochemical performance and pumping requirements in redox flow batteries, yet conventional carbon-fiber-based porous have not been tailored to sustain of liquid-phase electrochemistry. 3D printing is an effective approach manufacturing deterministic architectures, enabling tuning pressure drop. In this work, model grid structures are manufactured with stereolith...

A key element in stretchable actuators, sensors, and systems based on elastomer materials are compliant electrodes. While there exist many methodologies for fabricating electrodes on dielectric elastomers, very few succeed in achieving high-resolution patterning over large areas. We present a novel approach for the production of mechanically robust, high-resolution compliant electrodes for stre...

A conductometric microsensor for measuring methanol vapor was conceived, based on electrospun composite nanofibers of polyvinyl chloride (PVC) doped with nickel phthalocyanine (NiPc) deposited interdigitated electrodes (IDEs) as transducers. The nanofiber’s shape, structure, percent atomic content and thermal properties were studied. sensor showed good sensitivity (505µS.cm?1.(v/v)?1), low limi...

Electric stimulation is known to initiate signaling pathways and provides a technique to enhance osteogenic differentiation of stem and/or progenitor cells. There are a variety of in vitro stimulation devices to apply electric fields to such cells. Herein, we describe and highlight the use of interdigitated electrodes to characterize signaling pathways and the effect of electric fields on the p...

Escherichia coli O157:H7 is one of the leading bacterial pathogens causing foodborne illness. In this study, an impedance immunosensor based on the use of magnetic nanobeads and screen-printed interdigitated electrodes was developed for the rapid detection of E. coli O157:H7. Magnetic nanobeads coated with anti-E. coli antibody were mixed with an E. coli sample and used to isolate and concentra...
