Magnetic potential well tuning of resonant cantilever energy harvester
Magnetic potential well tuning of resonant cantilever energy harvester
Cantilever energy harvesters have presently been tuned by manipulating beam dimensions or by placement of a tip mass. While these techniques lend themselves well to designing a highly tuned resonance, the design is fixed and each system is unique to a specific frequency. Here we report investigations of magnetic potential well tuning to vary the spring constant, which shifts the resonance. The significance of this work is the design of a harvesting system with variable resonance, adjusted by changing the effective spring constant by means of shaped pole-pieces on a pair of magnets. Wider tuning range with reduced tuning force is thus achieved.

Abstract
Cantilever energy harvesters have presently been tuned by manipulating beam dimensions or by placement of a tip mass. While these techniques lend themselves well to designing a highly tuned resonance, the design is fixed and each system is unique to a specific frequency. Here we report investigations of magnetic potential well tuning to vary the spring constant, which shifts the resonance. The significance of this work is the design of a harvesting system with variable resonance, adjusted by changing the effective spring constant by means of shaped pole-pieces on a pair of magnets. Wider tuning range with reduced tuning force is thus achieved.
