  1. 1. Investigation of Gallium Nitirde High Electron Mobility Transistors

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Shikhar Arvind; [2021]
    Nyckelord :Gallium Nitride; High electron mobility transistor; leakage current; in-situ Silicon Nitride; power electronics;

    Sammanfattning : Gallium Nitride (GaN) based transistors have been in the spotlight for power electronics due to promising properties like high bandgap, high breakdown field, high electron mobility, and high-frequency applications. While there are some commercial devices based on these transistors available, there is still room for improvement in these devices for widespread usage. LÄS MER

    Sammanfattning : In industrial environments workers can be prone to dangerous situations that may cause harm. In order to prevent accidents and fulfill legislative requirements for safe working condition, a safety system can be needed to be installed in place. LÄS MER

  4. 4. Testbed Development for Non-invasive Intracranial Pressure Monitoring with a Microwave based Electromagnetic Skin Patch Sensor

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Sandra Palm; Hassan Saado; [2021]
    Nyckelord :Intracranial pressure; Artificial cerebrospinal fluid; Biomedical engineering; Microwave sensor;

    Sammanfattning : Traumatic brain injuries (TBIs) are a major public health problem worldwide where the symptoms can be anything from mild concussion to severe swelling of the brain tissue. As a result of TBI the intracranial pressure (ICP) can elevate to pathological levels with severe consequences such as hypoxia, ischemia and brain hemorrhage. LÄS MER

  5. 5. An evaluation of materials and processes suitable for manufacturing micro HASEL-actuators

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Anna Lindgren; [2021]
    Nyckelord :HASEL-actuator; paraffin blend;

    Sammanfattning : HASEL-actuators use dielectric liquids and compliant shells as their media. This type of actuatorwould suit the actuators used as fins for soft milli robots (SOMIRO). These robots are going tobe used in aquaponic crops for studying its impact on the environment to help the farmersimprove their crops. LÄS MER
