Because electric charges exert forces of attraction or repulsion on each other, we can consider how much force would be needed to move an electric charge from one point to another while feeling an electric force from another charged particle. Electric Potential Difference: the work done to move a ch ...

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.
