This research translates that biological function into an engineered sensing system for underwater platforms.</p> <p><strong>Technical Approach &amp; Methodology:</strong></p> <ul> <li><em>Design &amp; Fabrication</em>: Developed a soft, transparent, surface-mounted skin using electroactive plasticized polymer gels (EPPGs) integrated onto a rigid rectangular plate.</li> </ul> <h4 id="heading"></h4> <ul> <li><em>Fluid Dynamic Context</em>: Established the theoretical force distributions for flow over canonical shapes to predict sensor response.</li> </ul> <h4 id="heading-1"></h4> <ul> <li><em>Experimental Testing</em>: Conducted comprehensive flow tank testing to evaluate sensor sensitivity and voltage generation under varying hydrodynamic loads.</li> </ul> <h4 id="heading-2"></h4> <ul> <li><em>Multiphysics Simulation</em>: Developed a computational model in COMSOL Multiphysics to simulate gel deformation, providing a high-fidelity comparison between theoretical predictions and experimental results.</li> </ul> <h4 id="heading-3"></h4> <p>This work provides a framework for self-powered, transparent, &ldquo;smart&rdquo; skins that enable underwater vehicles to perceive their environment with the same tactile sensitivity as biological organisms.</p>
