Micromachined optical fiber current sensor.
We describe a micromachined optical fiber current sensor. The sensing element consists of a squared silicon membrane (8 mm long and 20 microm thick) that has a cylindrical permanent magnet (NdFeB alloy, 3-mm diameter, 1.5 mm high) fixed on its central region. This structure allows the permanent magnet to vibrate in the presence of the magnetic field gradient generated by an ac. A linear relatio...
متن کاملMicromachined Fiber Optical Sensor for In Vivo Measurement of Optical Properties of Human Skin
In this paper, we present the design, fabrication, and testing of a new micromachined fiber optic sensor probe to conduct oblique incidence diffuse reflectance spectrometry (OIDRS) for in vivo estimation of optical properties of human skins. The probe consists of three source fibers, two linear array of collection fibers, and four micromachined positioning devices for accurate alignment of the ...
متن کاملIntrinsic Optical Fiber Sensor
The use of more and more complex systems in transportation, bio medical devices, defence, production, systems, etc., that are more and more automated, having to comply with many norms related to low energy consumption, miniaturization, insensivity to modifications of the surrounding conditions, security, etc. induce the need of new sensors that have to be reliable, low cost, easy to produce, if...
متن کاملBulk Micromachined Pressure Sensor
Bulk micromachined piezoresistive pressure sensor was designed, fabricated, packaged, and tested at RIT laboratory facility. Every aspect of the fabrication is studied thoroughly and used as an educational tool in better understanding the fabrication of MEMs devices.
متن کاملHybrid Structure Multichannel All-Fiber Current Sensor
We have experimentally developed a hybrid-structure multi-channel all-fiber current sensor with ordinary silica fiber using fiber loop architecture. According to the rationale of time division multiplexing, the sensor combines parallel and serial structures. The purpose of the hybrid-structure multi-channel all-fiber current sensor is to get more information from the different measured points s...
