A COMPREHENSIVE REVIEW ON PIEZO IMPEDANCE BASED MULTI SENSING TECHNIQUE


Towards silent and efficient flight by combining bioinspired owl feather serrations with cicada wing geometry

Abstract As natural predators, owls fly with astonishing stealth due to the serrated feather morphology that produces advantageous flow characteristics.Traditionally, these serrations are tailored for airfoil edges with simple two-dimensional patterns, Abrasive limiting their effect on noise reduction while negotiating tradeoffs in aerodynamic perf
