Abstract
Components of an unmanned undersea vehicle are inspired by jellyfish that uses its flexible body and tilt sensing to achieve efficient swimming and turning. A tilt sensor, based on a statocyst, has a metal ball in a chamber lined with resistors. The tilt is sensed in accordance with which resistors the ball contacts. A composition of polyvinyl alcohol hydrogel with ferritin particles dispersed therein mimics the qualities of a jellyfish's mesoglea.
