A dynamic homogenization approach for modelling hybrid piezoelectric nanogenerators

Energy scavenging, from green and sustainable energy resources, is increasingly attracting the atten- tion of researchers and industries in several engineering fields. The main aim is capturing the energy, naturally available in the environment, and converting it into electrical energy. Emerging applica- tions, such as in flexible/strechable micro and nano electronics, biomedical monitoring, wearable technology, micro and nano robotics and extreme technology, require devices of smaller and smaller size and high performances.
