Sensing signal assessment in sensorial materials: key embedding conditions

Bringing real life to objects to serve various aspects of our life can fundamentally improve the quality of our life. This is allowed through new nervous materials hosting sensors and actuators. The material can, therefore, sense and react to sensing according to specifications. In an on-going research, this paper discusses the conditions of embedding of a variety of sensors inside materials e.g. conservation of integrity and adherence of sensors to materials, and investigates the sensing signal characteristics before and after embedding. The results show that the embedded or coated fiber optic shifts its central Bragg wavelength. The carbon fibers and carbon nanotube fibers, once embedded, have the ability to report about the hosting material defects by monitoring the resistivity signal behavior.
