Information on product use conditions is essential for sound strategies of product service as well as take back, refurbishing, reuse of components, or recycling. Further, it could improve design, market research and quality management. - The presentation describes modular concepts for life-cycle monitoring, identification of use conditions, reliability assessment and diagnosis. MEMS-based prototypes are discussed, which measures, identifies, and records data strongly correlated with the degradation of an electronic product during its use phase. They are designed to get embedded in various products. The product?s remaining life time can be estimated during its use by dedicated algorithms implemented in the data processing unit. The data recorded can be retrieved either during the use stage or after product take back. Life Cycle Information is valuable information with many benefits for the manufacturer of electronic components. The knowledge about the loads in use support ongoing trends to pay on availability and pay on production. Especially online analysis for condition monitoring is a challenging benefit. Current approaches to life cycle data acquisition and analysis are presented. The principles of condition monitoring are discussed. The concept of a Life Cycle Information Unit is presented and a prototype is discussed in detail.
