Pixel neurochip characterization

In this work a probe built for in-vivo neuronal recording is presented and analysed. Advantages that this design provide for extracellular potential measurements are discussed along with standard electro-physiological methods. Starting from simulations and physical characterizations the conditions necessary to properly operate the sensor are deduced. Issues and limitations will be discussed and addressed together with possible investigation methods. The final part consist in a discussion on high-k dielectric materials that can be included in the fabrication process of the chip. Impedance properties and parameters of interest from a biological standpoint are also extracted.
