A machine and structure reduce their own strength by the cumulative damage caused by fatigue generated by dynamic loads. If the signals caused by the development of crack in materials are able to be detected, the condition of health of a machine and structure will be monitored to prevent the sudden fracture of them. It was reported by authors that the signals of that can be detected by the wavelet transform of the observed signals such as displacement, velocity and acceleration etc, because the wavelet transform can detect the discontinuity in signals. However, the wavelet transform require the computed time for its transform and then it cannot be used for on-line monitoring. Then, it has been strongly desired to detect the discontinuity in signal of acceleration and then, the jerk sensor composed by a vibratory gyroscope and a cantilever has been developed for this purpose. The proposed sensor is manufactured and used for the experiment, which prove the availabilty of this proposed sensor.
