  1. 1. Capacitive Micromachined Ultrasonic Transducers for Underwater Applications

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Patrick Johansson; [2021]
    Nyckelord :CMUT; capacitive; micromachined; ultrasonic; transducer; model;

    Sammanfattning : Capacitive micromachined ultrasonic transducers (CMUT:s) are often used in medical imaging and they show some promise as underwater transducers. This thesis collates the available information about how CMUT:s operate, their strengths and weaknesses and investigates their efficiency as an underwater transducer. LÄS MER

  3. 2. On-line Verification of Hemodialysis Water Quality

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Johan Andersson; Elin Holmström; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Renal diseases are an increasing problem worldwide and when kidney transplantation is not possible, dialysis treatment is the solution. An increasing number of patients choose to perform their dialysis treatment at home by implementing the dialysis machine and a water purification system in current electric and water supply, so called home hemodialysis.

  4. 3. Tillverkning av mikronålar för medicinsk tillämpning

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för teknikvetenskaper

    Författare :Tomas Jäderblom; [2014]
    Nyckelord :;

    Sammanfattning : Transdermal drug delivery, besides painful injections with syringes, has long been associated with small size particle pharmaceuticals, which can diffuse through the skin. This method of drug administration has only been applicable on a small number of drugs, where active molecules are small and delivery time should or can be long. LÄS MER

  5. 4. Novel micromechanical bulk acoustic wave resonator sensing concepts for advanced atomic force microscopy

    Master-uppsats, KTH/Mikro- och nanosystemteknik

    Författare :Stefan Wagner; [2012]
    Nyckelord :;

    Sammanfattning : This thesis investigates novel concepts of micromechanical bulk acoustic wave sensors for advanced atomic force microscopy (AFM), using micromachined silicon resonators, which are analyzed with regard to their performance as compared to conventional AFM sensors. Conventional AFM systems use a cantilever resonator for sensing the surface forces of the sample. LÄS MER
