Electrochemical sensor with nano-wire array

摘要

An electro-chemical sensor comprises a bismuth nano-wire array. The sensor is used to detect incipient corrosion under paint. It is particularly useful in admiralty and marine applications such as for detecting incipient metal oxidation such as rusting and for monitoring the progress of metal oxidation on ship hulls and tanks. It is also useful in the automobile industry for quantifying surface quality in preparation for painting.
