1. 1. Cognition and communication in children/adolescents with cochlear implant

   Författare :Tina Ibertsson; foniatri och audiologi Logopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cochlear implant; working memory; conversational skills; request for clarification; reading; hearinr impairment; writing;

   Sammanfattning : A cochlear implant (CI) is a device that provides individuals with severe to profound hearing impairment (SPHI) with auditory stimulation, which makes it possible for them to develop skills related to spoken communication. We have little knowledge about how hearing with a CI influences cognitive and communicative development and there is a need for development of methods for assessment. LÄS MER

3. 2. Bone Conduction Hearing in Human Communication - Sensitivity, Transmission, and Applications

   Författare :Sabine Reinfeldt; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transcutaneous; one s own voice; bone conduction; occlusion effect; communication system; sensitivity; bone conduction implant; transmission; bone-anchored hearing aid; bone conduction microphone;

   Sammanfattning : Sound perceived via Bone Conduction (BC) consists of vibrations transmitted to the cochleae through the skull bone from either one's own voice, the surrounding sound field, or a BC transducer. In two-way communication systems, BC is believed to improve the sound quality when used in specific environments, e.g. LÄS MER

4. 3. Conjugated Polymers for Neural Interfaces : Prospects, possibilities and future challenges

   Författare :Maria Asplund; Hans von Holst; Olle Inganäs; Thomas Stieglitz; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neuroprosthetics; conjugated polymers; conducting polymers; PEDOT; functional electrical stimulation; neural electrodes; Medical engineering; Medicinsk teknik; Neuroscience; Neurovetenskap; Functional materials; Funktionella material;

   Sammanfattning : Within the field of neuroprosthetics the possibility to use implanted electrodes for communication with the nervous system is explored. Much effort is put into the material aspects of the electrode implant to increase charge injection capacity, suppress foreign body response and build micro sized electrode arrays allowing close contact with neurons.

5. 4. Wireless Communication with Medical Implants: Antennas and Propagation

   Författare :Anders J Johansson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical implant communication; electromagnetic propagation; biomedical telemetry; antennas in matter; MICS; Electronics; Elektronik;

   Sammanfattning : With the increased sophistication of medical implants, there is a growing need for flexible high-speed communication with the implant from outside the body. Today the communication is done by an inductive link between the implant and an external coil at a low carrier frequency. LÄS MER

7. 5. Neuromusculoskeletal interfacing of lower limb prostheses

   Författare :Alexander Thesleff; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OPRA; bone-anchored attachment; Enhanced Osseointegrated Prostheses for the Rehabilitation of Amputees e-OPRA .; Osseointegration; direct skeletal attachment; neuromusculoskeletal interface; OPRA; Osseointegrated Prostheses for the Rehabilitation of Amputees OPRA ; Enhanced Osseointegrated Prostheses for the Rehabilitation of Amputees e-OPRA .;

   Sammanfattning : The method of bone-anchored attachment of limb prostheses via a percutaneous skeletal extension was developed to circumvent commonly reported problems associated with the conventional method of socket attachment. In addition to the direct structural connection, the percutaneous implant may serve as a conduit for bidirectional communication between muscles and nerves within the residual limb and the prosthesis.
