  1. 41. Mechanical performance of 3D printed objects - Model and simulation of the material properties of selective laser sintered PA12 objects

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Anders Lindberg; [2018]
    Keywords : ;

    Abstract : Additive manufacturing is a technique allowing the building of complex geometries in a layerby-layer approach. These layers lead to an anisotropic material behaviour. In this report a material description for selective laser sintered (SLS) PA12, which is a common 3D-printing plastic, is investigated. READ MORE

  3. 42. Metal-on-Polymer Wear for Orthopaedic Hand Prostheses : Metall-på-polymer-slitage för ortopediska handproteser

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : CHLOE TECHENS; [2018]
    Keywords : orthopaedics prosthesis arthrosis trapezometacarpal biomaterial tribology friction wear;

    Abstract : Metal-on-polymer prostheses in orthopaedics are often subject to high wear level producing large polyethylene particles that the body has difficulties to eliminate. Those debris can lead to prosthesis loosening. READ MORE

  4. 43. The CB-hand

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Daniel Blomstrand; Erik Skarrie; [2018]
    Keywords : Technology and Engineering;

    Abstract : The purpose of the thesis was to design and build an externally powered prosthetic hand. The hand should preferably have one or more new functionalities not found in other prostheses. The human hand is very complex, it contains over 30 muscles and at least 18 joints. READ MORE

  5. 44. Finite Element Analysis of Osseointegrated Transfemoral Implant : Identification of how the Length of Implant Affects the Stress Distribution in Cortical Bone and Implant

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Anna Pogosian; [2018]
    Keywords : Osseointegrated; Implant; Transfemoral; Finite Element Methods;

    Abstract : An alternative method of conventional prosthesis is  osseointegrated transfemoral implant, in where the prosthesis is fixated directly to the bone. The benefits with this system is increased range of motion, sensory feedback and reduced soft tissue problem. READ MORE

  6. 45. Investigating the use of multi-label classification methods for the purpose of classifying electromyographic signals

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Petter Björklund; [2018]
    Keywords : Biomedical engineering; Statistical classification; Prosthetics; Technology and Engineering;

    Abstract : The type of pattern recognition methods used for controlling modern prosthetics, referred to here as single-label classification methods, restricts users to a small amount of movements. One prominent reason for this is that the accuracy of these classification methods decreases as the number of allowed movements is increased. READ MORE
