As the world is marching toward the era of the Internet of Things (IoTs), big data, and artificial intelligence, the widely distributed sensing networks are the most critical element for hardware development in this era. Given the need for mobility of numerous distributed electronic devices, the era of IoTs calls for distributed energy sources. The random and irregular micro-nano mechanical high entropy energy is a new promising recyclable energy widely distributed in the surroundings. The development of paired harvesting technology to high entropy energy is imperative to meet the requirements of booming sustainable energy in the new era of IoTs. Triboelectric nanogenerator (TENG), driven by Maxwell's displacement current, is a highly effective technology for micro-nano mechanical high entropy energy harvesting. TENG has the virtues of broad materials choice, low cost, easy manufacturing, wide adaptability, and industrial scalability. Moreover, the TENG has higher efficiency and output performance than an electromagnetic generator (EMG) at low frequencies (typically < 5 Hz). In addition, TENG can directly convert mechanical stimuli into electrical signals without additional power, which is of great significance for self-powered sensing. As the ocean contains abundant and clean renewable energy, large-scale blue energy harvesting can also be achieved by integrating many TENG units into one network. Therefore, TENG has a broad application prospect in harvesting high entropy energy: from tiny micro-nano energy to large-scale blue energy. TENG is not only applicable to the distributed energy demands of the IoT era, but also a promising paradigm of sustainable energy for gearing carbon neutral in the future.
