... If we want to have a reliable measurement of SI , it can be seen that many measurements are necessary. Suppose that we want to know the value of SI to 1/1000 √ and we measure the value of the current once per second. We can use the equation ΔSI /SI = 1/ βτ [6], where β is the bandwidth and τ is the ...

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.
