Abstract
Harvesting flexural energy has emerged as a viable means for driving low-power electronic devices. This study presents an optimized phononic gradient refractive index (GRIN) lens, which has important applications in focusing and harvesting elastic waves in fields such as structural health monitoring and wearable electronics. Also presented is a general framework for optimizing GRIN lenses, using multiple-scattering computations and ray-tracing analysis. Experimental results for an actual, optimized lens exhibit significant increase in focused power, with significant shortening of focal distance.
