  1. 1. Towards clinically viable neuromuscular control of bone-anchored prosthetic arms with sensory feedback

    Författare :Enzo Mastinu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromyography; prosthetics; sensory feedback; closed-loop; osseointegration; embedded system; pattern recognition; neurostimulation;

    Sammanfattning : Promising developments are currently ongoing worldwide in the field of neuroprosthetics and artificial limb control. It is now possible to chronically connect a robotic limb to bone, nerves, and muscles of a human being, and to use the signals sourced from these connections to enable movements of the artificial limb.

  4. 3. On the Utility of Representation Learning Algorithms for Myoelectric Interfacing

    Författare :Alexander Olsson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; Machine Learning; Deep Learning; Feature Learning; Biosignal Processing; Gesture Recognition; Muscle-Computer Interfaces; Myoelectric Control; Upper-Limb Prosthetics;

    Sammanfattning : Electrical activity produced by muscles during voluntary movement is a reflection of the firing patterns of relevant motor neurons and, by extension, the latent motor intent driving the movement. Once transduced via electromyography (EMG) and converted into digital form, this activity can be processed to provide an estimate of the original motor intent and is as such a feasible basis for non-invasive efferent neural interfacing.

  5. 4. Touching on elements for a non-invasive sensory feedback system for use in a prosthetic hand

    Författare :Pamela Svensson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sensory feedback; amputation; referred sensation; non-invasive feedback; upper limb prosthetics; body ownership;

    Sammanfattning : Hand amputation results in the loss of motor and sensory functions, impacting activities of daily life and quality of life. Commercially available prosthetic hands restore the motor function but lack sensory feedback, which is crucial to receive information about the prosthesis state in real-time when interacting with the external environment.

  7. 5. Optimization of Electron Beam Melting for Production of Small Components in Biocompatible Titanium Grades

    Författare :Joakim Karlsson; Håkan Prof.; Mikael Bäckström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; 3D-printing; Electron Beam Melting; Titanium alloys; Chemical properties; Mechanical properties; Surface properties; Additiv tillverkning; 3D-skrivare; Electron Beam Melting; Titan; Kemiska egenskaper; Mekaniska egenskaper; Ytegenskaper; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Additive manufacturing (AM), also called 3D-printing, are technologies where parts are formed from the bottom up by adding material layer-by-layer on top of each other. Electron Beam Melting (EBM) is an AM technique capable of manufacturing fully solid metallic parts, using a high-intensity electron beam to melt powder particles in layers to form finished components.
