ELECTRONIC DEVICE, METHOD AND COMPUTER PROGRAM FOR OLFACTORY ASSESSMENT OF A PRODUCT STATE

摘要

This electronic device (10) for assessing the state of a product that can change through emission of volatile organic compounds comprises olfactory sensors (18) which are designed to provide signals representative of the presence of volatile organic compounds in the ambient air close to the product, and a processor (36, 42, 44, 46, 48) for processing the signals provided in order to produce a signature that is representative of the state of the product. It further comprises a memory (50) for storing a reference signature which is representative of exposure of the olfactory sensors (18) to a reference humid environment in which the product is not present, and a computer (36, 54) which computes a value for the similarity between the signature representative of the state of the product and the reference signature in order to provide a product transformation index value from the computed similarity value.
