1. Conjugated Polymers for Neural Interfaces : Prospects, possibilities and future challenges
Abstract : 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.

2. Silicon neural interfaces -Design and biomedical aspects-
Abstract : This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon.

3. Infrared Neural Modulation: Photothermal Effects on Cortex Neurons Using Infrared Laser Heating
Abstract : It would be of great value to have a precise and non-damaging neuromodulation technique in the field of basic neuroscience research and for clinical treatment of neurological diseases. Infrared neural modulation (INM) is a new modulation modality developed in the last decade, which uses pulsed or continues infrared (IR) light with a wavelength of 1200 to 2200 nm to directly alter neural signals.

4. A novel implantable ultra-flexible brain machine interface. Manufacturing and initial characterisations
Abstract : This thesis describes for the very first time the development of a miniaturized neural interface which is flexible in three dimensions (3D) to enable it to follow the brain movements with minimal dislocation. Both the design rationale and the material choice for the electrodes aim to develop interfaces that minimize the damage and/or the irritation of the tissue during and after the implantation.

5. Towards Natural Control of Artificial Limbs
Abstract : The use of implantable electrodes has been long thought as the solution for a more natural control of artificial limbs, as these offer access to long-term stable and physiologically appropriate sources of control, as well as the possibility to elicit appropriate sensory feedback via neurostimulation. Although these ideas have been explored since the 1960’s, the lack of a long-term stable human-machine interface has prevented the utilization of even the simplest implanted electrodes in clinically viable limb prostheses.
