This study presents a novel flexible strain sensor for real-time strain sensing. The material for strain sensing is single-walled carbon nanonets, grown using the alcohol catalytic chemical vapor deposition method, that were encapsulated between two layers of Parylene-C, with a polyimide layer as the sensing surface. All of the micro-fabrication was compatible with the standard IC process. Expe...

In this study, numerical modeling of a multi-drain system is employed to determine the optimum penetration depth of prefabricated vertical drains (PVDs) and the vacuum pressure that provides the maximum consolidation settlement and less lateral displacements. The plane strain analysis using an equivalent permeability with transformed unit cell geometry was considered for varying drain length an...

scanning hall probe microscopy (shpm) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. this method is based on application of the hall effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  shpm provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...

effects of three pressure reduction rates (prr) of 103 pa s-1, 197 pa s-1, and 347 pa s-1 on temperature distribution and variation, moisture content, and sensory quality of steamed stuffed buns were investigated after vacuum cooling. the distributions and variations of surface temperatures were determined by the thermal infrared imaging method. the temperature profiles presented significant di...

The silicon based pressure sensor is one of the major applications of the piezoresistive sensor. This paper focuses on the structural design and optimization of the MEMS piezoresistive pressure sensor to enhance the sensitivity. A finite element method (FEM) is adopted for designing the performance of a silicon based piezoresistive pressure sensor. Thermal as well as pressure loading on the sen...

The extremely rapid reflection of a shock wave from the end wall generated in tube, addition to high-frequency content pressure, inevitably also excites mechanical vibrations. These can potentially produce acceleration-induced spurious signals as part dynamic output pressure measurement system being calibrated. This paper proposes and evaluates method for correcting frequency response obtained ...
