Towards Product Health Monitoring throughout its life-cycle

Product Health Monitoring (PHM) is the process of monitoring usage conditions of the product. Like Structural Health Monitoring systems, they are traditionally deployed during the Middle-Of-Life (MOL) phase of the product's life-cycle. The aim of this paper is to describe the concept of PHM throughout its life-cycle. Advances in Nanotechnology and wireless nano sensors networks allow envisaging their integration into many products and systems. From this observation, we propose to describe a system to monitor dimensional features of a product. The monitoring system uses self-organizing communication network principles. Thereby the product can perform its continuous health monitoring, regardless its physical transformations. Self-measurement system requires no specific sensors and is based on two techniques: neighborhood discovering and distance-ranging.
