An array of many bipolar electrodes (BPEs) can be controlled by a single pair driving yet allows for multiplexed analysis individual biomarkers or cells at once. A wide range electrochemical sensors have been devised, which operate under battery power and produce visible signals (e. g., luminescent, electrochromic) appropriate smartphone naked eye readout. These features BPEs are advantageous i...

Resistive-type semiconductor-based gas sensors were fabricated for the detection of methyl mercaptan and hydrogen sulfide. To fabricate these sensors, V2O5/WO3/TiO2 (VWT) particles deposited on interdigitated Pt electrodes. The vanadium oxide content utilized VWT was 1.5, 3, or 10 wt.%. structural properties investigated by X-ray diffraction scanning electron microscopy analyses. resistance sen...

An experimental/computation investigation was carried out to develop a MEMS-based micro cooling device to provide direct cooling to high heat flux electronics and MEMS devices. This device uses the electrohydrodynamic principles to pump and form an ultra thin film over a heated surface that requires cooling. The important part is played by applying an electric field to a set of interdigitated i...

Engineered skeletal muscle tissues are ideal candidates for applications in drug screening systems, bio-actuators, and as implantable constructs in tissue engineering. Electrical field stimulation considerably improves the differentiation of muscle cells to muscle myofibers. Currently used electrical stimulators often use direct contact of electrodes with tissue constructs or their culture medi...

This paper presents an original microchip device that manipulates planar x- and y-positions of dielectric microbeads over an electrode array with dielectrophoresis (DEP) effects. Implemented with a simple single-layer metal process, the microchip device consists of two parallel arrays of triangular-shaped electrodes. The two arrays of electrodes are arranged such that they locked into each othe...

A microchip that performs directed capture and chemical activation of surface-modified single cells has been developed. The cell capture system is comprised of interdigitated gold electrodes microfabricated on a glass substrate within PDMS channels. The cell surface is labeled with thiol functional groups using endogenous RGD receptors, and adhesion to exposed gold pads on the electrodes is dir...

Abstract We present results on very thin NiO films which are able to detect 3 ppm of acetone, toluene and n-butyl acetate in synthetic air operate at 300°C. with 25 50 nm thicknesses were prepared by dc reactive magnetron sputtering alumina substrates previously coated Pt layers as heater interdigitated electrodes. Annealed indexed the (fcc) crystalline structure their calculated grain sizes ra...

Optimization of interdigitated electrode sensor design is essential for practical impedance spectroscopy in the medical and pharmaceutical fields because their easy fabrication procedure inexpensive. The geometry presents a prospective ameliorating sensitivity over other microelectrode designs. geometric optimization sensor’s structure with interdigital electrodes one difficult problems. To sol...
