| Abstract(in English) | For high sensitivity ultrasonic sensor in air, nanofoam is applied to acoustic matching layer. Nanofoam is a porous material that is prepared through sol-gel reaction. Since Nanofoam has low acoustic impedance, it is effective for acoustic matching layer of ultrasonic sensor in air. In this study, we have made an ultrasonic sensor that has two acoustic matching layers and estimated the acoustic properties. Two matching layers are made of silica Nanofoam and porous ceramic. The sensitivity of ultrasonic sensor is about twenty times as high as a conventional ultrasonic sensor in air. |
