ABSTRACT:
A chemical or corrosive environment sensing system, comprising a giant magnetoresistive effect device having at least one environmentally exposed film, and a device, for sensing changes in the GMR effect device resulting from environmental exposure of the at least one environmentally exposed film. The film may be reversibly or irreversibly altered by the exposure, and is preferably nano-textured to alter a reaction rate and surface area. The sensor may be enzyme linked, that is, respond to an enzyme reaction product rather than the substrate directly. The GMR property altered and/or sensed may be, for example, a lower or upper switching field, an electrical resistance, and the GMR value. The device may be used as a sensor or as part of a control system.
