Development of ultrasound type kHz level human specific respiration sensor and application for finding survivor in a disaster zone.

In this research, we could realize new high-precision gas concentration sensor using ultrasound by using a new three-dimensional processing machine, to improve the detection accuracy. By adding a pseudo small frequency change system, we succeeded in the development of quasi-phase difference control mechanism. In addition, we were able to verify that our proposed sensor could detect a human being specific waveform in such a disaster area, even if it placed in the distance 2 m long from the survivor. The contents of the above three points, that is accepted 3 English journals. International conference IRIS2010, this proposal was awarded as the best award paper.
