DEGRADATION SENSOR FOR ENVIRONMENTALLY SENSITIVE PRODUCTS AND METHOD OF USE

摘要

An environmental degradation sensor (1201) for environmentally sensitive products (1205 provides the degraded state and estimated remaining life of a product. The sensor may be integrated with a passive RFID (1203) to provide product identification and degradation status wirelessly via reader (1211). A communications connection (1223) allows uploading product identification and degradation data to a network. The degradation sensor responds to multiple environmental stressors and integrates product degradation, requiring no electrical power until interrogated. The sensor improves product safety, reduces cost of premature product disposal and, combined with RFIDs, improves the security of products through combined product degradation monitoring and tracking.
