PING · Piezoelectric nanogenerators on suspended microstructures for energy harvesting

Since micro- and nanotechnology already allow to design devices which only require minuscule amounts of power, the ability to convert ""free"" energy ""harvested"" from the environment into electric energy has tremendous potential, especially with reference to implantable devices for medical applications and wireless sensors networks. However, existing approaches for energy harvesting are not sufficiently efficient, cheap, compact, and versatile
