| Abstract: | PVDF pressure sensor has been developed to measure shock waves in concrete structures. The work principle and design methodology of the sensor are briefly introduced. Stable capacity of the sensor has been verified through calibration tests, and the measuring error of the sensor can be reduced by sensitivity correction. Finally, application in stress wave measurement of explosion in concrete is discussed. |
