This paper introduces a method of embedding a piezoelectric patch to monitor the strength development of concrete and its subsequent structural health. The resonant and anti-resonant frequencies of an embedded sensor were monitored using an impedance analyser. Analysis determined that the most accurate method of determining the resonances was to monitor the phase diagram. The method was found to follow the expected strength development of the concrete. It was also investigated to determine if the AD5933 impedance chip can be used to reduce the size of the sensing system. It was found the when compared with the HP4192A values the AD5933 showed good potential as a tool for reducing the size of the monitoring system.
