Hybridized nanogenerators integrating two or more different energy harvesting units into an energy scavenging system for simultaneously harvesting multi‐types of energies in our living environment have the potential for effectively enhancing the total output performance. It is one of the most significant multiple energies scavenging technologies. The development of hybridized nanogenerators is based on maximizing the harvested energy from one type of energy by integrating the different energy scavenging units and achieving complementary harvesting of multiple energies. The large‐scale hybridized nanogenerator consisting of solar cells and TENGs will be a very powerful technology such as creating new wind–solar complementary energies scavenging systems.

The core of the coupled nanogenerators is based on multifunctional materials such as ferroelectric materials. The coupled nanogenerators have the same materials and the same electrodes, which can obtain various advantages of smaller sizes, lower cost, and higher integrations than the conventional integrated different nanogenerators. The coupling enhancement effect among the different physical effects has been found in the coupled nanogenerators. Considering the highlighted advantages and the ongoing related research hotspots, more breakthroughs in hybridized and coupled nanogenerators with respect to the design, performance, and applications for multiple energies scavenging and self‐powered multifunctional sensor networks will be seen in future.
