Piezoelectric Energy Harvesting

, 2016
This chapter reports on the modeling of electromechanically coupled beams with uniform and varying cross-sectional areas for energy harvesting. The governing equations are formulated by using the Rayleigh-Ritz method and Euler-Bernoulli assumptions. A resistive electrical load is considered in the electrical domain.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.
