Electronic active sensor with nano-pore array, e.g. for selective detection of magnetic fields, has high impedance conductive layer on surface of dielectric and ferrous fluid in nano-pores

摘要

The sensor has a high impedance conductive layer (HS) on a surface of the dielectric (D) and a ferrous fluid (F) in the nano-pores (NP). A small pore diameter ensures that a resistance of the high impedance conductive layer is measurable at the contacts (O, W, V). A characteristic curve follows a differential negative resistance behavior.
