Corrosion Sensors: II. Wireless Miniature Corrosion (original) (raw)

ECS Transactions, 2014

Abstract

The research reported here will focus on a miniature battery system that is inactive as assembled (“off”). It is activated when a damaging fluid flows into the inter-electrode separator (“on”). In the “on” state, it powers a wireless sensor that transmits a signal to the base station monitor to announce that corrosion conditions have been created at the location of the battery – sensor. Further, the battery-sensor powered the measurement of the time-to-failure (TTF) of a corroding specimen that was initiated when the fluid arrived (on), and ended when the specimen failed (off). The on/off action is a “large” signal that is insensitive to electrical noise from the ambient surroundings.
