Portable Sensor for Detecting Microbubbles in Real Time to Prevent Decompression Sickness for Safe Diving During Subaquatic Navy Activities

Abstract

The objective of this research project was to determine the feasibility of a new technology that would allow Navy divers to monitor in real time the presence, number and size of nitrogen bubbles, protecting them against DCS. We have successfully proven the feasibility of the idea. A system for generating air bubbles a small as 150 micrometers was developed. We were capable of detecting bubbles in the artificial blood vessels and in the artificial soft tissue. The electrical signals measured on the PZT were correlated to the size of the bubbles.
