A matched and self‐powered supply for a variety of wearable electronics remains a critical challenge. Here, a fully self‐powered early warning glove (SEWG) is developed via unique elastic‐arched triboelectric nanogenerator (EA‐TENG) and flexible printed circuit technology. The EA‐TENG generates electricity from a continuous touch lightly by hand or body, as a sustainable self‐powered source that can be utilized to complete one charging process by simply five times slapping. The SEWG has the advantage that can really deliver real‐time no‐contact electrostatic monitoring when no external power is supplied, and can effectively avoid the electric shock accident in 220/380 V electric maintenance work. Quantitative analysis of the mechanical and electronic characteristics of the SEWG demonstrated its advantages in terms of stability and reliability, with consistently well performance over more than 80,000 working cycles. It is anticipated that the special design of integrated self‐powered system could produce more implications in the field of wearable/flexible electronics and human‐machine interaction. A self‐powered early warning glove (SEWG) is designed and fabricated based on Faraday's law of electromagnetic induction and Ink‐jet printing technology. By touching an elastic‐arched triboelectric nanogenerator, real‐time no‐contact voltage/electrostatic monitoring can be achieved without external power supply. SEWG has the advantages of portability and longevity of service, providing a new approach for the field of self‐powered wearable electronics.
