Conjugated organic polymers can be doped, via oxidation or reduction chemistry or via acid}base chemistry, to induce very high electrical conductivity. Conjugated polymers are beginning to "nd uses, in both the neutral and the doped states, in prototype molecular-based electronics applications and in electronic and opto-electronic devices. The physical basis for the many of the unusual properti...

in this paper, a low-cost dynamometer for rolling, steered wheels is described. the dynamometer was constructed to determine whether such an instrumented mechanism was practical. four s-beam load cells, an opto-counter and a potentiometer were used to obtain all moments, and forces using dynamic and kinematic analysis. minimal simplifying assumptions considered for the required calculations. ov...

Optical detection has long been the most popular technique in immunosensing. Recent developments in the synthesis of luminescent probes and the fabrication of novel nanostructures enable more sensitive and efficient optical detection, which can be miniaturized and integrated with microfluidics to realize compact lab-on-a-chip immunosensors. These immunosensors are portable, economical and autom...

The application specific paper describes a design approach for digital opto sensors and data acquisition systems. It is based on the Universal Frequency-to-Digital Converter (UFDC-1) working well with any frequency output sensors, for example, lightand color-to-frequency converter from TAOS. Such design approach lets significantly simplify the design process, reduce time to market and productio...
