  1. 6. Control of 3D-printed Hand Prosthetic via Intra-body Fat Channel Communication

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Eric Trollsås; [2022]
    Nyckelord :Fat-IBC; IBAN; Prosthetics; ATE Phantom; Phantom Tissue; 3D-printing; ZigBee;

    Sammanfattning : Intra-Body Communication (IBC) is a prospective technology where human tissue may be used as a signal medium in order to transmit useful data within the human body. Proposed applica- tions of this technology are prosthetics control or implanted device communication, potentially by establishing an Intra-Body Area Network (IBAN), which could further be enhanced by other IoT applications and 5G radio systems.

  4. 8. Development Of Lung Phantoms for Detection Of Acute Respiratory Distress Syndrome

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Wassim Wahbeh; Youssef Hasan; [2022]
    Nyckelord :DARDS;

    Sammanfattning : The goal of this project was to fabricate a deflated and an inflated phantom to replicate how the human lung tissues’ permittivity changes under a pathological condition for instance acute respiratory distress syndrome (ARDS). Furthermore, the lung phantom should be shaped like real human lungs. LÄS MER

    Sammanfattning : The discovery of metamaterials has led to major advances in different fields of physics including optics, microwave engineering and acoustics. Specific to theoretical electromagnetism, the introduction of metamaterials have led to the development of negative-index materials (NIMs) with simultaneous negative permittivity and negative permeability with backward-wave propagation.
