Abstract	A cement based piezoelectric composite sensor was fabricated using the 1-3 cement based piezoelectric composite as a sensing element. The frequency response, linearity and sensing properties of the sensor were investigated. The results indicate that the output voltage amplitude of the sensor increase with increasing frequency of load under 5 Hz. When the frequency of load is larger than about 5 Hz, the output voltage amplitude of the sensor is nearly independent of frequency. There exists an obviously linear relationship between the output voltage amplitude and input load amplitude of the sensor. The 1-3 cement based piezoelectric composite sensor embedded into the concrete structure exhibits excellent sensing properties. The output voltages of the sensor are correspondent to the complex load, random load and pulse load very well. The phase difference between the output voltage and input load is near zero. The experimental output voltage value of the sensor is in good agreement with the theoretical value. Such sensor has a good potential to be used in civil engineering structural health monitoring.
