First Claim
Patent Images
1. A tilt sensor for sensing a tilt angle, the tilt sensor comprising:
- a support defining a cavity;
a plurality of electrical elements surrounding the cavity; and
a conductive object disposed in the cavity so as to move within the cavity in accordance with the tilt angle to change an electrical property of the tilt sensor to allow sensing of the tilt angle.

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.
