Interdigitated transducers (IDTs) were originally designed as delay lines for radars. Half a century later, they have found new life actuators microfluidic systems. By generating strong acoustic fields, trigger nonlinear effects that enable pumping and mixing of fluids, moving particles without contact. However, the transition from signal processing to comes with range challenges concerning pow...

A humidity microsensor integrated with a readout circuit on-a-chip fabricated using the commercial 0.18 μm CMOS (complementary metal oxide semiconductor) process was presented. The integrated sensor chip consists of a humidity sensor and a readout circuit. The humidity sensor is composed of a sensitive film and interdigitated electrodes. The sensitive film is titanium dioxide prepared by the so...

The study develops an integrated humidity microsensor fabricated using the commercial 0.18 μm complementary metal oxide semiconductor (CMOS) process. The integrated humidity sensor consists of a humidity sensor and a ring oscillator circuit on-a-chip. The humidity sensor is composed of a sensitive film and branch interdigitated electrodes. The sensitive film is zinc oxide prepared by sol-gel me...

Proton Exchange Membrane (PEM) fuel cells are becoming more popular as an energy conversion device because its efficiency and simplicity in design and operation. Significant improvements and recent developments in the areas of water and heat management, membranes, electrode designs, and, most recently, the interdigitated flow field design, have increased greatly the attractiveness of this syste...

Auxin is a multifunctional hormone essential for plant development and pattern formation. A nuclear auxin-signaling system controlling auxin-induced gene expression is well established, but cytoplasmic auxin signaling, as in its coordination of cell polarization, is unexplored. We found a cytoplasmic auxin-signaling mechanism that modulates the interdigitated growth of Arabidopsis leaf epiderma...

Host-cell factor 1 (HCF-1) is an unusual transcriptional regulator that undergoes a process of proteolytic maturation to generate N- (HCF-1(N)) and C- (HCF-1(C)) terminal subunits noncovalently associated via self-association sequence elements. Here, we present the crystal structure of the self-association sequence 1 (SAS1) including the adjacent C-terminal HCF-1 nuclear localization signal (NL...

Ž . A capacitive sensor has been developed for measuring the vertical deflection of bridge-type micro-electromechanical MEMS silicon actuators. The sensor requires no electrodes above the actuator surface and does not require the actuator diaphragm to be used as a signal electrode. Sets of interdigitated electrodes, one for ac signal injection and the other for signal sensing, are placed beneat...

This paper describes an advantageous method for using the capacitor banks in the distribution network, optimally. The aim is to determine the count, location and capacitor values in order to minimize the annual cost resulting from energy losses and capacitor bank’s installation cost. Besides, in the case of having nonlinear loads in the network, by installing capacitors in appropriate locations...
