Abstract: Sensors embedded in a Reinforced Concrete (RC) structure create a Structural Health Monitoring (SHM) system which could monitor issues detrimental to the health of RC. This paper will explore the possibility of using an array of Piezoelectric Micromachined Ultrasonic Transducers (PMUTs) as a means of transmitting data between such embedded sensors. Due to the acoustic properties of RC, the frequency of operation of such a system would ideally be around to or less than 100 kHz. This paper outlines the work conducted through Finite Element Modelling (FEM) using COMSOLTM and verified through experimental processes to predict the pressures which can be potentially created by a PMUT array.
