Resistance Resistivity and Conductivity
... Ohm’s Law: when the current through a device is proportional to the voltage applied across the device. When the resistance of the device is independent of the voltage across it. A material obeys Ohm’s law when the resistivity of the material is independent of the applied magnetic field. ...

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.
