Ultrasonic wave reception apparatus and obstacle detection apparatus |
摘要 |
<p>An obstacle detection apparatus includes a rubber-like elastic body interspersed with electroconductive particles, and means for applying a voltage to the rubber-like elastic body to obtain an ultrasonic wave reception signal from a change in electrical resistance of the elastic body. An ultrasonic wave transmission apparatus is mounted on a support member for transmitting an ultrasonic wave outward. The rubber-like elastic body interspersed with electroconductive particles is provided along an outer periphery of the support member, and a voltage is applied to the rubber-like elastic body to obtain an ultrasonic wave reception signal from a change in electrical resistance of the elastic body as a result of receiving the ultrasonic wave reflected from an obstacle.</p> |
