Abstract
In previous study, we developed a net-structure proximity sensor with optical detection elements and showed applications such as robot hand and human interface. However, the optical sensor cannot use in blurry vision and cannot detect a transparent object. We propose a new net-structure proximity sensor with ultrasonic detection elements. The sensor can resolve above problems and is applicable new detecting methods that utilize the ultrasonic waves. In this paper, we discuss demands to construct the ultrasonic net-structure proximity sensor. Secondly, we propose a constitution of the ultrasonic net-structure proximity sensor that fulfills the functions with ultrasonic elements.
