  1. 26. Finding Optimal Jetting Waveform Parameters with Bayesian Optimization

    University essay from KTH/Optimeringslära och systemteori

    Author : Stefan Xueyan Fu; [2018]
    Keywords : ;

    Abstract : Jet printing is a method in surface mount technology (SMT) in which small volumes of solder paste or other electronic materials are applied to printed circuit boards (PCBs). The solder paste is shot onto the boards by a piston powered by a piezoelectric stack. READ MORE

  3. 27. A Study on Interface Circuits for Piezoelectric Energy Harvesting

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Tang Honghao; [2018]
    Keywords : interface circuit; PEH system; switch;

    Abstract : A piezoelectric energy harvesting (PEH) system can harvest electrical energy from ambient vibration energy. In a PEH system, the interface rectifier circuit is critical because it converts AC from the output of piezoelectric harvester to DC that can power the load. READ MORE

  4. 28. Preparation and Characteristics of Bi0.5Na0.5TiO3 based Lead-Free thin films by Pulsed Laser Deposition

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ge Jiang; [2018]
    Keywords : PLD method; piezoelectric thin film; electrical properties; PLD-metoden; piezoelektrisk tunnfilm; elektriska egenskaper;

    Abstract : Lead-based piezoelectric materials, such as PbZrxTi1-xO3 (PZT), have attracted considerable attention and have been widely used in actuators, sensors and transducers due to their excellent electric properties. However, considering the toxicity of lead and its oxides, environmentally friendly lead-free piezoelectric materials are attracting more attention as potential replacements for PZT. READ MORE

  5. 29. Wireless Piezoelectric Horse Sensor System

    University essay from Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska fakulteten

    Author : Sandra Pantzare; Elin Wollert; [2018]
    Keywords : ;

    Abstract : The domestication of horses took place at least 2000 BCE. Since then, horses have been used for transportation, agricultural work and even for warfare. Today, horses have been bred into world athletes, used worldwide in equestrian sports. READ MORE

  6. 30. Acoustophoretic manipulation of sub-micron particles

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : David van Assche; [2017]
    Keywords : Technology and Engineering;

    Abstract : Microchannel acoustophoresis is a technique which uses acoustically induced forces to translate particles in a microchannel. Its use in biological applications is increasing. Using acoustophoresis to precisely manipulate bioparticles such as yeast, blood cells and cancer cells gives the technique great potential. READ MORE
