... When you place different amounts of charge in an electric field, they will each have different amounts of electric potential energy, even if you put them in the same place. Therefore, it is much more convenient to talk about the electric potential energy per unit of charge. This is called electric p ...

Nanogenerator
Nanogenerator is a technology that converts mechanical/thermal energy as produced by small-scale physical change into electricity. Nanogenerator has three typical approaches: piezoelectric, triboelectric, and pyroelectric nanogenerators. Both the piezoelectric and triboelectric nanogenerators can convert the mechanical energy into electricity. However, the pyroelectric nanogenerators can be used to harvest thermal energy from a time-dependent temperature fluctuation.
