Abstract

In this paper the experimental application of a new class of an optical pressure sensor based on polydimethylsiloxane (PDMS)-Au is shown. The sensor consists of a tapered bended optical fiber, where an optical signal goes across, embedded into a PDMS-gold nanocomposite material (GNM) and it is used for scanning surfaces while it is moved automatically by a controlled servomotor. The sensor data during the scanning may be used for detecting a small notch on a beam. The experimental results are very encouraging for foreseeing successful use of this new sensor in robotic applications.
