... When current flows through an object, there is always some resistance to this flow. A resistor is an object through which a current (I) flows when a voltage difference (V) is applied across the ends of the object. The resistance (R) of the resistor determines how much current flows for a given volta ...

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.
