Recording and stimulation using implantable neural implants has been demonstrated as an effective diagnosis and treatment for neurological disorders (i.e. Parkinson’s disease, epilepsy) as well as in neuroprosthesis applications. [1] Conventional devices are fabricated using rigid materials such as metal or silicon which has a significantly higher young’s modulus compared to the neural tissue leading to foreign body reaction (in chronic implantations) due to the mechanical mismatch. [2] Current research in the field is focusing on developing soft and flexible electrodes to better mimic and conform the natural tissue property and reduce the risk of implant rejection. [3] On the other hand, surgical implantation of ultra-soft electrodes to the target location in the brain in a minimally invasive manner remains a challenge. In addition, it is crucial to achieve minimum stab damage during insertion. Therefore, in this project, the goal is to fabricate shuttles using femtosecond laser ablation to facilitate the insertion of ultra-soft neural electrodes at the target site and achieve minimally invasive insertion as well as minimum stab damage to the neural tissue without buckling of the shuttle. Simulations of buckling force is used to optimise the geometry, size and material of the shuttle whereas the laser parameters are optimised for different materials (i.e. tungsten, stainless steel, silicon) to achieve a sharp shuttle tip. The insertion force required to penetrate neural tissue has been previously reported as a relevant metric to assess the extent of caused tissue damage. [4] Here we therefore optimize shuttle geometry, material, and fabrication process to minimize insertion force, which is measured using a motorised micromanipulator on a brain phantom at different insertion speeds. The fabricated shuttles will then be used for the implantation of ultra-soft electrodes.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
