This thesis is based on the design and characterization of a flexible neural interface based on NiTi microactuation. A neural interface is a device that may precede the connection of a limb prosthesis to the peripheral nervous system. One of the problem of tf-LIFE and TIMEIt is the post implant stability. In order to overcome the problem of micro-movements of the electrode in post implant was thought of introducing a shape memory material, a nickel titanium alloy, is chosen. Specifically it is opted to store a s shape of the alloy in the area of the active sites. These can be implemented and undergo a vertical displacement being closer to the initial position after implantation, improving the selectivity of the electrode.
