Project Details

Description

The use of cuff-based microelectrodes realized with massives fabrication technologies shows a wide range of higher performance related to the reproducbility, sensibility, reliability, resolution,life time, selectivity and cost, rebounding to its aplication on any type of nerve fiber. In the present project the main objetive is the development of a new technology derived from the MCM interconection microelectronic technology in order to obtain an array of cuff-based flexible microelectrodes, together with surface modification techniques (electrochemical platinization) can simplify the neuroprothesi due to the ability on diminishing the associated impedance of the microelectrode-electrolite (surround the nerve) interface, that, in short, and due to minor electrical restrictions less complex circuit can be designed. Finally, one of the most important challenge of the present project is the development of a recording circuitry able to obtain signals so lower than 5 uV in a contaminated ambient for signals showing higher ampliteds and lightly lower frecuencies. To obtain the desired objectives is indispensable to get ready an array of microelectrodes with a high frecuencies. To obtain the desired objectives is indispensable to get ready an array of microelectrode-fiber interface. The whole of researchers of the project are thinking on the necessary creation of a multidisciplinarity (microelectronic technology, electronic, instrumentation, biomedical-electrochemical-electrical characterization) team in order to achieve the set of the ambicious goals such as the presented in this projects.
