    Nyckelord :Energy harvesting; Prosthetic limbs; Supercapacitors; Printed circuit boards; 3D printing; Energiinsamling; Lemmproteser; Superkondensatorer; Tryckta kretskort; 3D Utskrivning; Orkuöflun; Gervilimir; Ofurþéttar; Prentaðar rafrásir; Þrívíddarprentun;

    Sammanfattning : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. LÄS MER

  3. 2. Real-time adaptation of robotic knees using reinforcement control

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

    Nyckelord :Machine learning; deep reinforcement learning; transfer learning; medical device; prosthetic; prosthesis; controls; human-in-the-loop; Maskininlärning; djup förstärkningsinlärning; överföringsinlärning; medicinsk utrustning; protes; kontroller; människa-i-loopen;

    Sammanfattning : Microprocessor-controlled knees (MPK’s) allow amputees to walk with increasing ease and safety as technology progresses. As an amputee is fitted with a new MPK, the knee’s internal parameters are tuned to the user’s preferred settings in a controlled environment. LÄS MER

  4. 3. Elastic Net Regression for Prosthesis Control in Short Residual Limb Amputees: Performance and Generalizability

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Oskar Berg; [2023]
    Nyckelord :Neuroengineering; Statistics; Biomedical Signal Processing; Technology and Engineering;

    Sammanfattning : This Master's thesis in Biomedical Engineering investigates the performance and generalizability of linear regression models in context of prosthesis control for short residual limb amputees. This thesis uses intramuscular electromyography data, and a regression and emplys a regression technique called Elastic Net Regression - a technique that combines L1 and L2-regularization - to predict 1-DOF isometric forces outputs from fingers and the wrist.

  5. 4. Effekt av spegelterapi som en omvårdnadsåtgärd för smärtlindring av fantomsmärtor: En kvantitativ litteraturstudie

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Emelie Piri; Emilia Rydström; [2023]
    Nyckelord :Amputees; reducing phantom limb pain; mirror therapy; nursing measures; phantom pain.; Amputerade personer; fantomsmärta; smärtlindring av fantomsmärtor; omvårdnadsåtgärder; spegelterapi.;

    Sammanfattning : Bakgrund: Majoriteten av de personer som genomgått ett amputationsingrepp drabbas av fantomsmärta. Trots att fantomsmärta är ett vanligt fenomen inom denna patientgrupp så är det ofta missförstått och det föreligger problem förknippade med hanteringen av fantomsmärtor. LÄS MER

  7. 5. Real-time Control Modelling and Output Signal Data Analysis Based on the Stewart Platform

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

    Nyckelord :Prosthesis; Stewart platform; Simulation; PID control; Kalman filter; Protes; Stewart-plattform; Simulering; PID-kontroll; Kalman-filter;

    Sammanfattning : Around 40 million people around the world have amputated parts of their bodies. Prostheses are widely used to support their daily behavior. However, about 35% of amputees refuse to use the prostheses due to comfort problems. SocketSense is an EU research project that aims to improve the situation. LÄS MER
