Abstract

Journal of Vibration and Control, Ahead of Print.
Low-amplitude vibrations represent a vast untapped energy source, but conventional harvesters fail to generate usable power below critical thresholds. This paper presents a novel magneto-spring mechanism that fundamentally transforms pendulum-based energy ...
