Energy Harvesting
First Claim
1. An apparatus comprising:
- a plurality of transducer elements configured and arranged to provide a collective energy-transduction area corresponding to a plurality of individual energy-transduction areas respectively defined by the plurality of transducer elements, each of the plurality of transducer elements configured and arranged to convert energy waves conveyed via a multi-directional radiation pattern into electrical charge;
a power-accumulation circuit configured and arranged to accumulate electrical charges from each of the plurality of transducer elements; and
each of the plurality of transducer elements is configured and arranged at different respective off-axis angles relative to an axis at which the energy is being conveyed, and wherein the power-accumulation circuit is configured and arranged to accumulate energy from each of the individual energy-transduction areas such that the energy waves reach the plurality of individual energy-transduction areas at the different respective off-axis angles for contributing to the accumulation of electrical charges.

Abstract
As may be implemented in accordance with one or more embodiments, an apparatus and/or method involves a plurality of transducer elements that convert energy waves conveyed via a multi-directional radiation pattern into electrical charge. A power-accumulation circuit accumulates electrical charges from each of the plurality of transducer elements, with each of the transducer elements being arranged at different respective off-axis angles relative to an axis at which the energy is being conveyed. The power-accumulation circuit accumulates energy from each of the individual energy-transduction areas, such that energy received at different respective off-axis angles contributes to the accumulation of electrical charge.
