A capacitor-type engine oil sensor is designed and fabricated to measure the property of diesel depending on vehicle mileage. This has flat structure with interdigitated (IDT) electrodes for smooth flow constructed using printed circuit board (PCB) fabrication convenience. For increased capacitance, smaller spacing between preferred determined 0.5 mm based limit. The device applied actual truck...

The design of interdigital transducers (IDT) for active structural health monitoring (SHM) systems often requires a tuning their characteristics specific applications. IDTs are generally preferred the selectivity Lamb’s guided modes, but directivity radiation pattern is parameter that difficult to customize complex mechanical structures. This work proposes comprehensive experimental study IDT w...

Air-stable semiconducting inks suitable for complementary logic are key to create low-power printed integrated circuits (ICs). High-performance printable electronic with 2D materials have the potential enable next generation of high performance low-cost digital electronics. Here, authors demonstrate air-stable, low voltage (<5 V) operation inkjet-printed n-type molybdenum disulfide (MoS2), and ...

The design, development and performance evaluation of a novel radio frequency microelectromechanical systems (MEMS) gyroscope, based on a surface acoustic wave resonator (SAWR) and a surface acoustic wave sensor is presented in this paper. Most of the MEMS gyroscopes based on silicon vibratory structures that utilize the energy transfer between the two vibratory modes demand small fabrication t...

This paper presents a new numerical approach for the full extraction of coupling-of-modes (COM) parameters by stationary and eigenfrequency analyses in finite element method (FEM). is fast extracting from results static analysis analysis. It avoids long calculation time admittance frequency response analysis, which commonly used COM parameters. In addition to usual (velocity, reflection coeffic...

To investigate the parameters of sucrose dust explosion, minimum ignition energy (MIE) and temperature (MIT) were evaluated. The experiments tested MIE under different conditions quantity, delay time (IDT), powder injection pressure (PIP). MIT particle sizes. results demonstrate that three was an open-up quadratic polynomial. When IDT, PIP 0.5 g (417 g/m3), 90 ms, 150 kPa, respectively, 58.9 mJ...
