Abstract
Since the electromagnetic induction effect was discovered by Michael Faraday in 1831, the electromagnetic generator (EMG) has been invented as the most important mean for power generation. In terms of the triboelectric nanogenerator (TENG), it can provide not only microscale energy for powering micro/nano systems, but also macroscale energy for powering portable electronics and household appliances, which is likely to be a parallel or possibly equivalently important technology as the traditional EMG for power generation. The TENG can be considered as a current source with a large internal resistance, while the EMG is equivalent to a voltage source with a small internal resistance. Besides, the TENG is demonstrated to be irreplaceable and unbeatable for harvesting low-frequency, small-amplitude, and low applied torque mechanical energy, which makes it complementary with the EMG for effectively harvesting mechanical energy. Here, the systematic analysis and comparison of EMG and TENG are demonstrated from their working mechanisms, governing equations and output characteristics, aiming at establishing complementary applications of the two technologies for harvesting various mechanical energies.
