  1. 1. Piezoelektrisk taktilåterkoppling i industriellabildskärmsdatorer

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Warut Chanadisai; Wendy Yap; Bashir Alturkmani; [2023]
    Nyckelord :Piezoelektricitet; Piezoelektrik sensor; Piezo; Haptisk återkoppling; Haptisk feedback;

    Sammanfattning : This project studies how tactile feedback can be implemented in existing CrossControl products,in this case the V1200-display computer. The main purpose of this function is to minimizedistraction for the user by implementing tactile feedback which creates the possibility for theuser to use the device without looking at the display.

  3. 2. Enhancing Sensing in Nanoscale: Investigation of Smart Nanomechanical Cantilever Array

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Hiruy Michael Weldegiorgish; [2022]
    Nyckelord :Cantilever; AFM; Biosensor; Piezoresistive sensor; Piezoelectric actuator; Kantilever; AFM; Biosensor; Piezo -resistorer; Piezo-elektiska pådrivare;

    Sammanfattning : In this report, a novel smart nanocantilever with self-deflection sensor using embedded piezo-resistor and self-actuation using integrated piezo-electric actuator is proposed, designed and simulated to enable highly sensitive label free biosensor and ultra-short cantilever probe for AFM applications. The smart nanocantilever comprises of a triangular Si3N4 nanocantilever (10µm long, 400nm width and 100nm thickness) connected to a multi-layer support structure (Si3N4 (100nm)/PZT (100nm)) having n-type silicon piezo resistor (7µm long ,2µm width and 20nm thickness) embedded in the Si3N4 layer in both the support structure and nanocantilever.

  4. 3. Quality Prediction in Jet Printing Using Neural Networks

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Daniel Brun; Colin Lawless; [2020]
    Nyckelord :;

    Sammanfattning : Surface mount   technology   is   widely   used   in   the   manufacturing   of   commercial  electronics, and  the  demands  on  the  machines  increase  as  the  complexity of  the electronics increases and the size of the components decreases. Mycronic is a company that focuses on addressing those demands with their high-technology jet printing and pick-and-place machines. LÄS MER

  5. 4. Techniques to inject pulsating momentum

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Strömningslära och experimentell mekanik

    Författare :Jelle Kranenbarg; [2020]
    Nyckelord :Hydro power; Rotating Vortex Rope; Flow control; Fluidic actuator; Synthetic jet actuator; Piston actuator; CFD;

    Sammanfattning : Hydro power plants are an essential part of the infrastructure in Sweden as they stand for a large amount of the produced electricity and are used to regulate supply and demand on the electricity grid. Other renewable energy sources, such as wind and solar power, have become more popular as they contribute to a fossil free society. LÄS MER

  7. 5. Investigation of Control Approaches for a High Precision, Piezo-Actuated Rotational Stage

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Niklas Ericson; [2016]
    Nyckelord :Rotational stage; Piezoelectric actuator; Integral resonance control; Adaptive control; External disturbance rejection; Harmonic cancellation;

    Sammanfattning : The Equipment Controls and Electronics section (EN-STI-ECE) at CERN is developing a high precision piezo-actuated rotational stage for the UA9 crystal collimation project. This collaboration is investigating how tiny bent crystals can help to steer particle beams used in modern hadron colliders such as the Large Hadron Collider (LHC). LÄS MER
