Abstract

Systems methods, and structures are provided that scavenge mechanical energy to provide electrical energy to a wearable, where the mechanical energy is scavenged by a bending-strain-based transducer that includes a non-resonant energy harvester. The bending-strain-based transducer also includes a sensor and/or a haptic device. The transducer may comprise a piezoelectric layer comprising a low-K piezoelectric material, such as aluminum nitride, which enables generation of higher voltage and power/energy output and/or a thinner transducer. Transducers in accordance with the present disclosure can be included in wearables for which large transducer thickness would be problematic, such as shoe insoles, midsoles or outsoles, garments, bras, handbags, backpacks, and the like.
