Under the proper orientations and excitations, the transverse output of rotationally symmetric four-contact van der Pauw (VDP) stress sensors depends upon only the in-plane shear stress or the difference of the in-plane normal stresses on (100) silicon. In bridgemode, each sensor requires only one four-wire measurement and produces an output voltage with a sensitivity that is 3.16 times that of...

This manuscript analyzes the effects of design parameters, such as aspect ratio, doping concentration and bias, on the performance of a general CMOS Hall sensor, with insight on current-related sensitivity, power consumption, and bandwidth. The article focuses on rectangular-shaped Hall probes since this is the most general geometry leading to shape-independent results. The devices are analyzed...

Abstract Graphene has shown considerable potential for sensing magnetic fields based on the Hall Effect, due to its high carrier mobility, low sheet density, and low-temperature dependence. However, cost of graphene in comparison conventional materials meant that uptake electronic manufacturing been slow. To lower technological barriers bring more widespread adoption sensors, we are using a one...

Power quality monitoring is a theme in vogue and accurate frequency measurement of the power line is a major issue. This problem is particularly relevant for power generating systems since the generated signal must comply with restrictive standards. The novelty of this work is the development of a smart sensor for real-time high-resolution frequency measurement in accordance with international ...

Since displacement is a vital variable to be considered in many industrial applications, sensing devices have been extensively studied both theoretically and experimentally. There also studies on Hall effect-based measurement, but for systems linearity still remains problem. This paper discusses different approaches calculate the magnetic field due cylindrical permanent magnet proposes new setu...
