In such branches of industry as agriculture, pharmaceutical, metallurgical, chemical, mining, and a number others, it is necessary to determine the mass consumption amount loose material, grain, cereals, flour, specific components chemical pharmacological materials cement, others. Ways measuring are component in automation systems modern production processes specified industries. Without use de...

Anticipating the requirement for highly radiation-tolerant silicon microstrip sensors suitable for the SLHC application, we have fabricated n-in-p microstrip sensors in p-FZ and p-MCZ industrial wafers which we then irradiated with 70MeV protons. Studies were made of the leakage current, onset of microdischarge, body capacitance, charge collection efficiency, and n-strip isolation at the fluenc...

Dual-mode surface-plasmon resonance (SPR) sensors use both long- and short- range surface plasmon waves to differentiate surface binding interactions from interfering bulk effects. We have optimized the design of these sensors for minimum surface limit of detection (LOD) using a Cramer-Rao lower bound for spectral shift estimation. Despite trade-offs between resonance width, minimum reflectivit...

presently there are a number of fine and sensitive methods for determining chemical or biochemical substance among which bio electrodes represent the most recent development. bioelectrodes consist of biologically active materials (e.g enzyme, antibody, whole cell or cell fragments) held in close proximity to a suitable electrochemical transducer that sense specific electroactive enzyme substrat...

Wafer bonding techniques play a key role in the present day silicon bulk micromachining for MEMS based sensors and actuators. Various silicon wafer bonding techniques and their role on MEMS devices such as pressure sensors, accelerometers and micropump have been discussed. The results on the piezoresistive pressure sensors monolithically integrated with a MOSFET differential amplifier circuit h...

We investigated selective detection of the target volatile organic compounds (VOCs) nonanal, n-decane, and acetoin for lung cancer-related VOCs, and acetone and methyl i-butyl ketone for diabetes-related VOCs, in humid air with simulated VOC contamination (total concentration: 300 μg/m³). We used six "grain boundary-response type" sensors, including four commercially available sensors (TGS 2600...
