A significant share of the gross national product is lost each year as a result of property damage due to corrosion. The cost of corrosion damage is a significant cost to the United States army and affects
troop deployment and readiness. Army vehicles require periodic inspection. An efficient way to monitor corrosion effectively and with fewer personnel is to embed nanosensors. These nanosensors will provide
an early warning on the onset of corrosion and enable corrective actions to be taken. This paper provides an insight into the application of nanocrystaUine materials into the various types of corrosion sensors.
