This paper presents the development of a new force sensor with MR elastomer as a sensing element. One key element in this study was to find a suitable material with high sensing capabilities which can be used for developing a sensor. Thus different MR elastomers, with ingredients of carbonyl iron particle, graphite, silicone oil and silicone rubber, were manufactured and measured with a modified rheometer. The effects of additives on the sensing capabilities were systematically investigated and an optimal MR elastomer sample was selected for design and manufacturing of a force sensor prototype. The development sensor prototype consists of three …

Conducting polymers have a wide range of reversibly controllable properties, leading to a number of potentially useful devices for robotic applications, including actuators, sensors and batteries. Conducting polymers have the advantages of low weight, low cost, flexibility, small activation potentials (

This paper presents a novel feature-based sensor distribution approach for root cause analysis and diagnosis of product 6-sigma variation faults in multi-station assembly processes. Traditional approaches in sensor distribution are based on the assumption that measurement points can be selected at arbitrary locations on the part or subassembly. This causes challenges such as difficult calibration of measurement system, increased errors of measured features, and lack of explicit relations between measured features and geometric dimensioning and tolerancing (GD&T). In the proposed approach, we develop methodology to maximize the number of measurement points that are placed at critical design features called Key …

Electrical characteristics and neutron dosimetry properties of silicon based p-i-n diodes are presented in support of the applications in the sensors for beam monitoring and medical physics. Both the current-voltage (I-V) and capacitance-voltage (C-V) characteristics of silicon planar p-i-n diode sensors with cylindrical geometry have been theoretically modeled and experimentally measured. The shifts of the forward and reverse diode characteristics of the sensors versus the neutron dose have been obtained. It is shown that the neutron irradiation caused shift of the forward voltage of the p-i-n diodes is proportional to the current at which it is measured in the case …

A fiber-optic temperature sensor based on the interference of selective higher-order modes in circular optical fibers is described. The authors demonstrate that by coupling the LP01 mode in a standard single-mode fiber to the LP0m modes in a multimode fiber, and utilizing the interference of the higher-order modes, a fiber-optic temperature sensor which has an extremely simple structure and is suitable for high-temperature measurements can be constructed. The sensing principle, temperature measurement experiments, and results are presented.

This paper presents a cost-effective sensor design based on an arrangement of light dependent resistors (LDRs) to determine the particle flow velocity and the particle concentration of granular material flow. The sensor is designed for both dense phase and dilute phase flow and can be applied wherever a transparent sightglass is used in material conveying. The measurement setup and its applicability for industrial conveying processes are discussed and measurement results utilising plastic pellets are presented.
