  2. 1. Evaluation of biomedical microwave sensors : Microwave sensors as muscle quality discriminators in laboratory and pilot clinical trial settings

    Author : Viktor Mattsson; Robin Augustine; Mauricio Perez; Roger Karlsson; Ayca Özcelikkale; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microwave sensors; Sarcopenia; Muscle quality assessment; Biomedical applications; Tissue dielectric properties; Data-driven modelling; Clinical trials; EM Simulations; Phantom experiments; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : In this thesis the primary focus is on the evaluation of biomedical microwave sensor to be used in the muscle analyzer system. Lower muscle quality is one indicator that a patient can have sarcopenia. Therefore the muscle analyzer system can be a tool used in screening for sarcopenia. READ MORE

  4. 2. Silicon neural interfaces -Design and biomedical aspects-

    Author : Lars Wallman; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; pn-etch stop; biocompatibility; neural recordings; porous silicon; silicon; neural interface; sieve electrode; General biomedical sciences; Biomedicinska vetenskaper allmänt ;

    Abstract : This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon.

  5. 3. Circuit Design Techniques for Implantable Closed-Loop Neural Interfaces

    Author : Nikola Ivanisevic; Ana Rusu; Saul Rodriguez; Angel Rodriguez Vazquez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neural interface; ECoG; high-resolution; ADC; recording; delta-sigma modulator; system identification; impedance measurements; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Implantable neural interfaces are microelectronic systems, which have the potential to enable a wide range of applications, such as diagnosis and treatment of neurological disorders. These applications depend on neural interfaces to accurately record electrical activity from the surface of the brain, referred to as electrocorticography (ECoG), and provide controlled electrical stimulation as feedback.

  6. 4. Development of a polymer based neural probe - How to record intracortical neural activity while minimizing the tissue response

    Author : Fredrik Ejserholm; Avdelningen för Biomedicinsk teknik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neural Probes; Electrode Modification; Polymer; Neurophysiology; OSTE ;

    Abstract : Intracortical neural probes have in the last couple of years been developed from stiff single probes to stiff multi-electrode neural probes to flexible multi-electrode neural probes. One reason for the change in design is that more than one recording/stimulation electrode, as in the case with a single wire, is needed for more advanced studies. READ MORE

  7. 5. Microelectrode cluster technology for precise interactions with neuronal circuits. Towards highly specific adaptive deep brain stimulation

    Author : Mohsin Mohammed; Neuronano Research Center (NRC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neuro-electronic interfaceneural interface; neural interface; tissue reactions; deep brain stimulation; Adaptive DBS; biocompatibility; implantation method; neurosurgical tool;

    Abstract : Neuro-electronic interfaces, which can be used for stable communication between neurons-computers over long periods of time, would be valuable for understanding and interacting with the nervous system. A major challenge has been to overcome the tissue reactions towards implanted electrodes. READ MORE
