Piezoelectric zinc oxide nanostructures have been recently used to convert mechanical energy into electrical energy. Here we give reasons for previously reported experimental results and provide insight for the design of high-efficiency piezoelectric nanogenerators. Moreover, we investigate some of the most important 2-contacts piezoelectric nanowires by means of Finite Element Method (FEM) simulations.
Nanotechnology has the potential to allow the development of more effective and less invasive methodologies for the diagnosis and treatment of many diseases. In particular, wirelessly-linked implantable nanotransducers are nanodevices capable of transducing signals from one energy domain into another, and they also allow the interaction of internal or external macroscopic systems with implantable...
