Variations in electrical impedance over frequency might be used to distinguish the degree of atopic dermatitis (AD), even if the mechanisms of the skin barrier impairment due to AD are still unknown. We observed the skin bioimpedance of normal mice and of abnormal mice having atopic with instrument measuring electrical impedance. Electrical impedance was measured from 20Hz to 1MHz at many frequencies...
This paper presents a numerical method for calculating the frequency response of a CMUT with a large number of cells. In a multi-cell configuration, commonly found in CMUTs, each cell is affected by the acoustic loading from neighboring cells. Thus, for an accurate model of a multi-cell CMUT element it is better to consider the mutual acoustic impedance instead of the acoustic impedance of a single...
This paper presents the excellent enhancement of power integrity (PI) by using through-silicon-via (TSV), which gives very small inductance to power distribution network (PDN) and consequently makes PDN impedance very low by sharing PDNs of 3-dimensionally (3-D) stacked chips. In this paper, the enhanced PI is shown by comparing that of wire-bonding applied 3-D stacked chips. A single SG (Signal/Ground)-TSV-pair...
In this paper, we propose a new loop tag for near field communication in UHF band. The proposed loop tag is composed of a loop structure for coupling to reader and a microchip for modulation. Specially, the suggested loop tag differs from a general single loop tag in that there are a number of linked loops as a antenna body to enhance the near magnetic field. To understand impedance matching principle...
