We present a printable interdigital structure, integrated into the surface of a component, to monitor the curing of two adhesively joint components during the fabrication process. In the factory of the future there is a need of new sensor concepts beside the information technological infrastructure. Monitoring of the fabrication enables automated control of the process which improves the qualit...

-Interdigital gate Si-MOSFET have been fabricated and electrically tested. Theb photodetection performances are also evaluated and compared with straight

The performance of capacitive interdigital sensors involved with anisotropic and inhomogeneous nematic liquid crystal (LC) film is investigated. These sensors have potential applications in chemical and biological systems. The theory for modeling the permittivity tensor of the LC film as a function of the molecular orientation is presented. The LC film is handled as inhomogeneous material where...

During limb development, the interdigital mesenchyme has been proposed to play a signaling role instructing morphogenesis of different digit types, as well as undergoing programmed cell death necessary to free digits in animals not adapted for swimming or flying. We have generated a conditional, tamoxifen-dependent Cre line, Bmp2CreER, which drives highly selective recombination restricted to t...

This paper presents a micromachined bandpass filter with miniature size that has relatively outstanding performance. A silicon-based eight-order microstrip bandpass filter is fabricated and measured. A novel design method of the interdigital filter that can create two transmission zeros is described. The location of the transmission zeros can be shifted arbitrarily in the stopband. By adjusting...

Because all microstrip antennas have to be matched to the standard generator impedance or load, the input impedance matching method for antenna is particularly important. In this paper a new methodology in achieving matching impedance of a planar microstrip antenna for wireless application is described. The method is based on embedding an Interdigital capacitor. The fine results obtained by usi...

In this paper we extend the continuum model for interdigital dielectrometry sensors and propose a new, direct technique for estimating material electrical properties from measurements. Interdigital sensors consist of alternating pairs of long, thin electrodes on a plane. An ideal model assumes that the periodic structure extends to infinity and the electrodes have no thickness. We extend this i...

BACKGROUND Alcohol sclerosing therapy has been reported as a safe and effective means of treating interdigital neuromas, both with or without ultrasound. The use of ultrasound introduces beside the ultrasound device, increased cost, and the need for skilled technicians and may reduce usability, especially in the outpatient clinic. We report a series of patients with interdigital neuroma treated...

We present the analysis and measurement of spurious responses generated at the ends of interdigital transducers (IDT). Filters fabricated on LiNb03 show an unwanted pass band ripple whose period indicates additional generation of acoustic waves at the IDT end. As this effect cannot be explained by methods of analysis based on the infinite array approximation, an exact analysis of the complex-va...
