Abstract
A selectively configurable beam and systems utilizing such are disclosed. The distribution of mass of the beam can be selectively adjusted or altered by adjusting one or more characteristics of the beam. Specific strategies utilizing continuous electro-wetting, and selective formation or movement of gases in liquid are disclosed. The selectively configurable beams are used in systems for harvesting vibrational energy from vibrating bodies.
