Biomimicking of a Swim Bladder and Its Application as a Mini-Generator

Abstract

A model fish with a man-made swim bladder achieves fast vertical motions based on density adjustments in a pressure-responsive way. When exposed to a magnetic field, a mini-generator is achieved by harvesting energy from the environment, working with pressure differences in the blood-pressure range and at the frequency of a beating heart.

Keywords: diving-surfacing cycles; mini-generator; mini-motor; pressure-responsive; smart devices.
