Human-machine interfaces (HMIs) have been highlighted with the advent of wireless sensor networks (WSNs) and the internet of things; HMIs may require wearable/attachable electronics exhibiting stretchability, biocompatibility, and even transmittance. Furthermore, due to limited weight and volume for wearability, energy efficient and even self-powered devices are required. Here, we report practical approaches for stably self-powered and transparent attachable ionic communicators (STAICs) based on self-cleanable triboelectric nanogenerators. STAICs can be easily applied on human skin due to their softness and its chemically anchored robust layers. STAICs function as real-time WSNs for communicating between humans and machines. Surface functionalization on STAICs by (Heptadecafluoro-1,1,2,2-tetrahydrodecyl)trichlorosilane improves sensitivity of STAICs and makes them electrically and optically stable due to the self-cleaning effect without sacrificing transmittance. This research will be a foundation for potential development of attachable ionics, self-powered sensor networks, and monitoring system for biomechanical motion.
