CORROSION MONITORING
This abstract first appeared for US patent application 18923044 titled 'CORROSION MONITORING
Original Abstract Submitted
A corrosion sensor is disclosed, including a corroding metal thin film encapsulated with an electrically insulating polymer layer, wherein the polymer layer is permeable to a corrosive gas by diffusion. An increase in the electrical resistance of the corrosion sensor, under exposure to corrosive gas that corrodes the corroding metal thin film when the corrosive gas permeates the polymer by diffusion, provides an indication of corrosion.
