With the rapid development of science and technology, people's demand for sustainable energy is increasing. Triboelectric nanogenerator (TENG) which achieves self power supply with all kinds of weak mechanical energy is helpful to alleviate this demand. Noncontact triboelectric nanogenerator (NC-TENG) can improve the stability and service life of TENG. The latest research progress of NC-TENG was summarized to provide a useful reference for structural design and performance optimization of NC-TENG. According to the structure and optimization method of NC-TENG, different NC-TENGs and their performance were introduced, focusing on their application in intelligent packaging, to look forward their performance optimization and application in the future. Based on different assembly structures, performance optimization schemes such as modulation of dielectric constant and addition of charge trapping interlayer could effectively avoid electrostatic discharge and improve the charge retention of NC-TENG. Compared with TENG, NC-TENG has higher stability and longer service life. It shows great potential in dealing with energy and promoting emerging electronic products. It is expected to have a wide application prospect in the field of intelligent packaging.
