Paper Abstract

Damage prognosis of structures and systems can be significantly improved by developing intelligent sensors with adaptive sensitivity to the ambient signals via self-tuned criticality. Active amplification of weak signals using an inherent dynamical sensory mechanism which is maintained at the threshold of an oscillatory instability is proposed in this paper as a general framework for designing and developing sensors for damage detection and prognosis for civil and mechanical systems. This idea is inspired by the sensing mechanism of mammalian cochlea to develop a new sensing system paradigm. A numerical feasibility study of such a sensor system is conducted and presented as a building block for more general design and future implementation.
