Customizing Triboelectric Nanogenerator on Everyday Clothes by Screen‐Printing Technology for Biomechanical Energy Harvesting and Human‐Interactive Applications

Abstract Integrating self‐powered sensors or energy harvesters with everyday clothes brings a novel insight into wearable electronics and improves personal intelligence in the era of the Internet of Things. This work develops a customizable screen‐printed textile triboelectric nanogenerator (SPT‐TENG) for biomechanical energy harvesting and human‐interactive applications. The as‐fabricated textile TENG not only presents excellent wearing experiences such as lightweight, permeability, and washability, but also exhibits high electrical output performance to power sustainably some portable electronics such as a watch or calculator. The system‐level wearable human‐interactive applications, including a wireless keyboard and a smart home appliance control, are also demonstrated with the advantages of cyber security, easy operation, low cost, and wearability through screen‐printing pattern‐customized TENG arrays. Benefiting from these features, the SPT‐TENG shows promising applications in wearable electronics, human‐machine interfaces, and artificial intelligence.
