| Abstract(in English) | Nanofoam material is a porous material that is prepared through sol-gel reaction. Since Nanofoam has extremely low acoustic impedance in solid state materials, it is effective for acoustic material of ultrasonic sensor in air. In this study, we have measured acoustic properties of Nonofoam materials and made ultrasonic sensors that had two acoustic matching layers. Two matching layers are made of silica Nanofoam and porous ceramic. The sensitivity of the ultrasonic sensors were about twenty times as high as a conventional ultrasonic sensor in air. In addition we have proposed a new type ultrasonic sensor in air that used ultrasonic refraction at the boundary between Nanofoam and air. The properties of the prototypes of the new type ultrasonic sensor are reported too. |
