Traditional technologies, such as electrochemical-based sensors, are not suitable for use in environments with intense pressures, temperatures and corrosive potential. Moreover, conventional sensors often fail due to instabilities associated with packaging, wires, and interconnects.Additionally, current sensing approaches arenotideallysuitedforwideareamonitoringduetotheneedforadirectelectricalconnectionatthesensinglocation.New sensing approachesthatpermitmonitoringoverwideareasarecriticallyneeded. The sensing methods under development eliminate these concerns while offering safety advantages and compatibility with scalable semiconductor-based manufacturing techniques.Additionally, these advanced sensor platforms that are capable of wireless and distributed early corrosion detection. Deployment of sensors using this technology will allow for embedded, real-time, remote corrosion sensing capabilities in extreme subsurface environments.
