... Electricity flows from areas of high resistance to areas of low resistance. In other words, it flows in the direction in which a positive electron would move. But how does energy actually move? Well, a solid conductive material contains a large number of mobile electrons. These weakly bound ele ...

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.
