  1. 1. Karakterisering av en mikrosensorsnål för mätning av syrehalt och konduktivitet

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Gustav Raittila; [2024]
    Nyckelord :Akupunkturnål; konduktivitetsmätning; medicintekniskprodukt; mikrosensor; syremätning;

    Sammanfattning : This report focuses on the characterization of an acupuncture needle microsensor, designed tomeasure the conductivity and oxygen saturation of tissues in the body, in particular musculartissues. The device is intended to help the practitioner localize and treat sources of chronicneuromuscular pain in patients. LÄS MER

  3. 2. Multiple Fibre Bragg Grating Force Sensor

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Felix Fritzén; [2023]
    Nyckelord :FBG force sensor; Fiber Bragg Grating force sensing; Fiber optic force sensor; Optical force sensing; Strain-based force sensing; Bragg wavelength shift; Force measurement using FBG; Fiber optic sensing technology; Fiber optic grating sensor;

    Sammanfattning : The purpose of this project is to explore the FBG (Fiber Bragg Grating) technology and create a force sensor. The result can be used as a basis for further projects.The project starts with force and strain measurements. The project then evolves to incorporate multiple FBG sensors. LÄS MER

  4. 3. Practical Trials of Fiber Optical Gyroscope Based Inertial Navigation System

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Tim Djärf; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : There exists a need for inertial navigation systems within a multitude of applications, such as drones, unmanned vehicles, and guidance systems. Saab produces gyroscopes for stabilization purposes, but the gyroscopes could also be used as part of an inertial navigation system. LÄS MER

  5. 4. Development of a validation shape sensing algorithm in Python with predictive and automatedanalysis

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Carlos Castellanos; [2021]
    Nyckelord :python; FBG; deflection; wavelength; machine learning; forecast;

    Sammanfattning : Difficulties with wind turbines can arise during operation due to externalforces provoked by the wind. Calculating the deflection of the blades can beused to give break points for maintenance, design and/or monitoring purposes. LÄS MER

  7. 5. Distributed Temperature Sensing Using Phase-Sensitive Optical Time Domain Reflectometry

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Simon Ek; [2020]
    Nyckelord :Applied physics; Distributed optical fiber sensing; Rayleigh scattering; OTDR; phase-OTDR; Temperature; Refractive index; Strain; Correlation; RISE; Single mode fiber; SMF; Tillämpad fysik; Distribuerad optisk fibermätning; Rayleigh-spridning; OTDR; phase-OTDR; Temperatur; Brytningsindex; Töjning; RISE; Korrelation; Singelmodfiber; SMF;

    Sammanfattning : This thesis explores and evaluates the temperature measuring capabilities of a phase-sensitive optical time-domain reflectometer (φ-OTDR), which exploits Rayleigh backscattering in normal single mode optical fibers. The device is constructed and its setup explained, and a protocol for making temperature measurements with it is developed. LÄS MER
