In this paper, we developed a new self-excited force sensor with a tunning-fork-beam for measurement of inverse problem. The proposed force sensor has the following characteristics: 1) high heat resistant 2) wireless measurement 3) potential for multiplex 4) possibility of miniaturization The key part of the proposed sensor is the tunning-fork-beam whose frequency changes under tensile force and undergoes self-excited vibration by the flow of air. Firstly, the principle of the proposed sensor is explained. Secondly, the simple theoretical analysis is performed. In order to verify the principle of the proposed sensor, the prototype sensor was built with acrylic material, then experiment was conducted with the prototype sensor. The spectrum of recorded sound was analyzed and the vibration of the sensor with outstanding frequency was observed. Measured relationship between the tensile load and frequency was shown to be consistent with the result of theoretical analysis.
