Progress and Recent Realizations of Miniaturized Inductive Proximity Sensors for Automation
IEEE Sensors Journal, 2006Noncontacting inductive proximity sensors (IPSs) are widely preferred for position detection in industrial applications. Advances in computer-aided design simulation tools, integration, and assembly techniques for the last ten years have made possible continued sensor-feature improvements in parallel to size reduction toward very small miniaturized ...

A novel architecture for inductive proximity sensors using sigma delta modulation
ESSCIRC 2007 - 33rd European Solid-State Circuits Conference, 2007This paper presents a novel architecture for inductive proximity sensors using sigma delta modulation. The LC-oscillator is included in the sigma delta control loop providing amplitude regulation and high precision analog-to-digital conversion in one block.

Implementation of inductive proximity sensor using nanoporous anodic aluminum oxide layer
2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, 2011This study presents an inductive proximity sensor implemented through the integration of nano-texture metal-spiral and np-AAO (anodic aluminum oxide (AAO) with nanopores) insulation layer on Si-substrate. The advantages of such nano-structure inductive proximity sensor are as follows, (1) The surface area of nano-texture metal-spiral is increased. Thus,

Metallic profile and coin imaging using an inductive proximity sensor microsystem
Sensors and Actuators A: Physical, 1998Abstract We have realized metallic profile and coin imaging using a miniaturized inductive proximity sensor. The sensor is a microsystem composed of a 1 mm diameter coil and a new ASIC interface based on the principle of a differential relaxation oscillator. We successfully acquired wellrecognizable images of various coins with different geometrical,

Fully Integrated Sensor Electronics for Inductive Proximity Switches Operating up to 250 °C
Additional Conferences (Device Packaging, HiTEC, HiTEN, and CICMT), 2019Abstract In this paper we present an integrated circuit for inductive proximity switches which requires very few external components and can operate under ambient temperatures up to 250 °C. The sensor system is realized in the Fraunhofer IMS H035 technology which was specifically developed for high temperature operation.

This study demonstrates a novel tri-axial piezo-resistive tactile sensor vertically integrated with a inductive proximity sensor using standard CMOS process (Fig. 1). Normal and shear loads sensing capabilities are achieved by measuring the signal changes of four piezo-resistive cross beams.

Design of an inductive proximity sensor using a two-coil planar transformer
SPIE Proceedings, 1995Here we present results for a new inductive proximity sensor that makes use of two coupled coils, forming a planar transformer, fabricated on a micromachined membrane. Macroscopic proximity sensors based on eddy-current techniques are currently commercially available. However, their design is not conducive to scaling inductor.

Study of variable inductance transducers as proximity sensors: I. Computer-assisted study
Measurement Science and Technology, 1990The authors are concerned with the computer-aided study of magnetic circuit/coil/target systems for proximity inductive sensors: for this study software for computation of magnetic parameters is used. A specific method for using the software and the results obtained by applying this method to four typical geometries of magnetic circuits are presented ...
