1. 1. Capacitive Micromachined Ultrasonic Transducers for Underwater Applications

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Patrick Johansson; [2021]
   Keywords : CMUT; capacitive; micromachined; ultrasonic; transducer; model;

   Abstract : 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. READ MORE

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

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Johan Andersson; Elin Holmström; [2016]
   Keywords : Technology and Engineering;

   Abstract : 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. Novel micromechanical bulk acoustic wave resonator sensing concepts for advanced atomic force microscopy

   University essay from KTH/Mikro- och nanosystemteknik

   Author : Stefan Wagner; [2012]
   Keywords : ;

   Abstract : 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. READ MORE
