A polyimide-based flexible wireless wall temperature sensor has been proposed for unsteady wall temperature measurements of internal combustion (IC) engines. The sensor is equivalent to an LCR resonant circuit including a sensing capacitor and a planar coil, which is coupled with an external read-out coil. The temperature changes lead to shifts of the resonant frequency, which is determined with the dip in the phase angle of complex impedance. The 1 mm-square sensing capacitor consists of suspen...

The single-, double- or multiple-cell entrapment efficacy is crucial in various aspects of biological studies. In this study, both computational and experimental approaches were conducted to explore the effect of the cell and microwell sizes on the ability of cell-trapping in a triangular microwell. From computational studies, it was found that the interaction between a spanwise vortex on the upper part and counter-rotating streamwise vortices at the leading edge helped to form a pair of seconda...

This paper presents a capacitive volatile organic compound (VOC) detector with parylene E-coated high-aspect-ratio (HAR) deep electrodes, which opens up a new design framework for high-sensitivity and low limit-of-detection detectors with low power consumption. From evaluations of the VOC sensing performance in steady-state flow, the sensitivity of the HAR detector achieves 48 times higher than that of the planar type with the same width and gap. In GC experiments, the present HAR detector captu...

This paper presents a dual-stage electrode design for electret-based rotational energy harvester (EH) to improve efficiency of synchronized switch harvesting on inductor (SSHI) technique. With the aid of the present parallel SSHI circuit, the output power of rotational electret EH becomes 2.6 times higher than that with the conventional circuit using a resistive load.

The liquid–air interface of Cassie droplets on superhydrophobic/superlyophobic surfaces has been directly captured with a high-precision laser displacement meter. The measured profile of the interface shape and the critical voltage with which the Cassie-to-Wenzel transition occurs are compared against those from numerical simulations of the electric field coupled with the interface shape. Under the applied voltage, the collapsing behavior of water, glycerol, and hexadecane droplets on SU-8, CYTO...

Abstract Wall chemical effect on DME/air weak flames ( U in = 1.5 cm/s, ϕ = 0.85) was investigated using a micro flow reactor with a streamwise temperature gradient experimentally. The quartz channel used in this study has a rectangular cross-section of 1.5 × 5 mm, which offers a good optical access for the planar laser-induced fluorescence (PLIF) measurement. The walls can be replaced for examining wall chemical effects of different wall materials. Wall surface materials, quartz, SiC, type 321 ...
