Electrogenerated chemiluminescence at electrodes with effective diameters down to 155 nm was used as a stable light source for near-field scanning optical microscopy imaging of an interdigitated array and a submicrometer size test substrate. Light was generated in a thin (approximately 500 microm) layer of an aqueous solution of 15 mM Ru(bpy)3(2+) and 100 mM tri-n-propylamine in a pH 7.5 buffer...

Spectral-Domain Optical Coherence Tomography (SD-OCT) is an optical method capable of 3D imaging of object's internal structure with micron-scale resolution. Modern SD-OCT tools offer the speed capable of online monitoring of printed devices. This paper demonstrates the use of SD-OCT in a simulated roll-to-roll (R2R) process through monitoring some structural properties of moving screen printed...

ing into widespread use for the trace determination of easily oxidizable and reducible organic and inorganic compounds, because it provides a rather easy procedure for direct and selective detection. Recently, microelectrodes have been receiving attention in this field (1,2). They offer higher sensitivity than macroelectrodes of conventional size, because an electroactive molecule can approach ...

This paper reports on conception, simulation, and fabrication of a lead zirconate titanate (PZT) MEMS cantilevers for piezoelectric energy harvesting (EH). We investigate the advantages of interdigitated electrode configurations (IDE) with respect to parallel-plate electrodes (PPE) in terms of output voltage and output power from the constitutive equations of piezoelectricity. Finite element mo...

Multiwall carbon nanotubes (MWCNTs) were easily and efficiently decorated with Pd nanoparticles through a vapor-phase impregnation-decomposition method starting from palladium acetylacetonates. The sensor device consisted on a film of sensitive material (MWCNTs-Pd) deposited by drop coating on platinum interdigitated electrodes on a SiO₂ substrate. The sensor exhibited a resistance change to oz...

Electromanipulation of microparticles utilizing microelectrodes has demonstrated considerable promise for the characterization, separation and handling of biological cells. Presently considerable research and development effort is directed towards the development of miniaturized fluidic systems with integrated dielectrophoresis (DEP) electrodes. The design, development and fabrication of a DEP ...

A prototypical metal-organic framework (MOF), a 2D periodic porous structure based on the assembly of copper ions and benzene dicarboxylate (bdc) ligands (Cu(bdc)·xH2O), was grown successfully as a thin film on interdigitated electrodes (IDEs). IDEs have been used for achieving planar CMOS-compatible low-cost capacitive sensing structures for the detection of humidity and volatile organic compo...

A micro power generator for harvesting vibration energy by means of a piezoelectric laminated cantilever with inertial mass was designed, fabricated, and characterized. The device was micro machined from a silicon-on-insulator structure coated with a 2μm thick piezoelectric PZT thin film. Interdigitated electrodes (IDE) were applied to achieve higher voltages. A piezoelectric coupling constant ...
