| Outline of Final Research Achievements |
Using the manufactured small type of sensor using a CMOS inverter oscillator circuit, it was shown that, by taking the difference of both outputs of dummy gauge and a strain gauge for measurement, strain can be measured with same accuracy as that by ordinary bridge circuit system. Next, the small type of strain sensor for wireless transmitting digital strain output was developed. For improvement of the sampling frequency, the strain measurement sensor combining CMOS inverter oscillator circuits and the reciprocal counting method was constructed. In addition, it was shown that the damage of the specimen under cyclic load can be detected based on the strain measurement by these sensor using CMOS inverter oscillator circuits. Moreover, the method for measuring static strain and dynamic strain with sufficient accuracy by the strain sensor using CMOS inverter oscillator circuits was derived.
