Some experimental and computational efforts to sense Line Currents (IL), Air Charging Currents (ACC) & Leakage Currents (ILK.), which are normally associated with the High Voltage (HV) utility power systems, are exerted. The low cost Giant Magneto Resistive (GMR) sensors are successfully manipulated to measure very large values of IL. GMR manipulations such as distance and angle alterations are...
An innovative investigation of optical feedback or self-mixing interference within the cavity of a single-longitudinal-mode laser is described as an integral part of a novel interrogation scheme to be employed in a fiber Bragg grating-based sensor for strain measurement. The entire sensor device simply consists of a laser diode with an integrated photodiode which is coupled to a fiber Bragg grating...
Stress sensing test chips are widely utilized to investigate integrated circuit die stresses arising from assembly and packaging operations. In order to utilize these test chips to measure stresses over a wide range of temperatures, one must have values of six piezoresistive coefficients for n- and p-type silicon over the temperature range of interest. However, the literature provides limited data...
