A wake absorber, wherein an aquatic vehicle with a propulsor mounted on the vehicle
and operative to propel the vehicle through a water medium, has a wake absorber
mounted on the vehicle aft of the propulsor. The wake absorber includes an artificial
muscle surface adapted to be impinged upon by a wake created by the propulsor.
The wake absorber further includes electrodes mounted on the artificial muscle
surface. Pressure of the wake upon the muscle surface exercises a bending force
on the surface, which creates energy that is recovered by the electrodes as electrical
power that can be digitized. Energy removed from the muscle surface by the electrodes
weakens the wake and renders the wake less pronounced visually and acoustically.
