Textile-based electronics have attracted increasing interests due to the huge demand for wearable technologies. Working as the energy harvesting devices, textile triboelectric nanogenerators (t-TENGs) have exhibited remarkable superiority in mechanical energy harvesting for the future lightweight, portable, flexible, and green energy supply in wearable system. Here, a brief review will be given focusing on the recent progress of t-TENG, including the evolution of device structure, demonstrations of various self-powered systems, further integration capability with other kinds of energy devices, etc. All of these progresses reveal the power of this mechanical energy harvesting technology as a very appealing part in wearable electronics.
