Abstract: © 2019, © 2019 Taylor & Francis Group, LLC. The aim of this paper was to study the electrical signal produced by the commercial piezoelectric buzzer by impact testing. The experiment varied external resistor, sphere weight, incident angle of sphere weight, impact position, the depth of the embedded piezoelectric buzzer in concrete and the impact surface of the embedded piezoelectric buzzer in concrete. As a result, we found that the suitable external resistor is 500 ohm which was related with resonant resistance of piezoelectric buzzer. The electrical signal increased as a result of the increased impact force on piezoelectric buzzer. The impact force will increase as the sphere weight falls at the middle of the piezoelectric buzzer. It is expected to explain electrical signal of piezoelectric buzzer by quantitative evaluation which is the key to understand physical mechanism to embedded piezoelectric materials in the structural health monitoring application.
