The RF community has long been searching for the ideal switch since birth of electronics, and it is defined as a device having virtually no insertion loss (Ron = 0 Ω) over wide frequency range, very high isolation [off-state capacitance (Coff)] fF), extremely linearity (IIP2 IIP3 → infinite), medium- to high-power handling (100 mW 1 kW), dc power consumption. Our entire infrastructure ecosystem, from communication system networks, satellite systems, wideband spectral analysis,...

The field of complex microfluidic channels is rapidly expanding toward with variable cross-sections (i.e., beyond simple rounded a constant diameter), as well whose trajectory can be outside single plane. This paper introduces the use three-dimensional (3D) printed soluble wax cast molds for rapid fabrication truly arbitrary polydimethylsiloxane (PDMS) that are not achieved through typical soft lithography. directly from computer-aided design files, followed by dissolution using solvent...

Double squirrel cage rotor design is employed in induction motor applications that require high starting torque and efficiency operation. The outer of double rotors vulnerable to fatigue failure since it must withstand the large thermal/mechanical stresses experienced during a loaded startup due current long acceleration time. However, there are only few publications investigate broken bar detection for motors. In this paper, detectability bars motors most commonly used test methods...

A liquid lens based on the electrowetting phenomenon was designed to be cylindrical minimize dead area. The fabricated with microelectromechanical-system (MEMS) technology using silicon thin film and wafer bonding processes. multiple dielectric layer comprising Teflon, nitride, thermal oxide formed cylinder wall. With a change of 11 Vrms in applied bias, module, including lens, showed focal length approximately 166 mm. capsule endoscope assembled, successfully used take images pig colon at...

As OPB and IPB moment-induced fatigue damage on mooring chain links were reported for a offloading buoy, verification of has been key engineering item in offshore structure design. Mathematical physical features the conventional approach which was mainly explained BV guideline are reviewed disadvantages addressed terms stress proportionality nonlinearity moments. In order to eradicate these disadvantages, novel is newly proposed able dispel apprehension not dependent nonlinearities...

The capsule endoscope, a new application area of digital imaging, is growing rapidly but needs the versatile imaging capabilities such as auto-focusing and zoom-in to be an active diagnostic tool. liquid lens based on MEMS technology can strong candidate because it able small enough. In this paper, cylinder-type was designed Young-Lippmann model then fabricated with combining silicon thin-film process wafer bonding process. focal length module including changed reproducibly function applied...

Cholesteric liquid crystal (CLC) has a helical structure with either of left-handedness or right-handedness. Due to the structure, selective reflection occurs depending on chrial pitch. However, reflectance CLC layer is theoretically limited 50% because only one right- left-handed circularly polarized light reflected. In this paper, we demonstrate high double for color reflector application.

Flexible capacitive humidity sensors are promising for low-cost, wearable, and radio frequency identification sensors, but their nonlinear response is an important issue practical applications. Herein, the linearity of was controlled by surface water wettability operating sensor, mechanism explained in detail condensation. For a sensor with Ag interdigitated electrode (IDE) on poly(ethylene terephthalate) substrate, capacitance showed small linear increase up to 70% RH large higher range....

To develop an optical sensor that mimics the neuromast, a sensory organ in fish used to detect movement, vibration and pressure gradient, we propose design of pillar, structure with robust properties underwater, present conditions analysis results for simulating displacement pillar flow field.

Although the Doppler velocity log is widely applied to measure underwater fluid flow, it requires high power and inappropriate for measuring low flow velocity. This study proposes a sensor that utilizes optical sensing. The proposed mimics neuromast of fish by attaching phosphor two pillar structures (A B) produced using ethylene propylene diene monomer rubber. signal emitted measured camera. An experiment was conducted apply an external force reactive part push-pull gauge confirm...

This paper describes a miniaturized oxygen sensor array integrated with heaters and temperature sensors LabVIEW-based measurement system which exactly can measure cellular respiration level in solution containing cells simultaneously. The designed consists of Clark-type sensors, heaters, 2 times 3 type on the substrate. 18 mum PDMS was used for permeable membrane sensor. 90% response time about 10 sec from full-oxygen (air-saturated) state to zero-oxygen (0.1 M Na <sub...
