Nanowire electrode sensor

摘要

The invention provides a sensor device comprising a nanowire electrode and a faradic shield, said faradic shield being made of a conductive material positioned between two dielectric passivation layers and being adapted to prevent unwanted capacitive charging current in said sensor and prevent electric fields from interfering with the nanowire electrode. The nanoelectrode device design with a metallic Faradic Shield layer significantly reduces the noise levels, increase the sensitivity of the sensors and allow measurements to be undertaken in less than 1 second. The sensor is also contemplated as a nanowire electrode array.
