Abstract

The development of both commercial and research driven wireless Acoustic Emission (AE) devices has increased in recent years. These have the potential to substantially improve the ease at which AE can be monitored, and so reduce the cost of doing so. Monitoring AE wirelessly has significant differences to other Structural Health Monitoring (SHM) applications; this chapter gives some key challenges faced and an overview of available systems. The development and testing of a state-of-the-art, low power, device for AE monitoring of bridges is also presented. Testing showed this device to be capable of continuous monitoring of a bridge structure, utilizing photovoltaic energy harvesting and novel power saving approaches.
