ABSTRACT
Self-powered system that is interface-free is greatly desired for area-scalable application. Here we report a self-powered electroluminescent system that consists of a triboelectric generator (TEG) and a thin-film electroluminescent (TFEL) lamp. The TEG provides high-voltage alternating electric output, which fits in well with the needs of the TFEL lamp. Induced charges pumped onto the lamp by the TEG generate an electric field that is sufficient to excite luminescence without an electrical interface circuit. Through rational serial connection of multiple TFEL lamps, effective and area-scalable luminescence is realized. It is demonstrated that multiple types of TEGs are applicable to the self-powered system, indicating that the system can make use of diverse mechanical sources and thus has potentially broad applications in illumination, display, entertainment, indication, surveillance and many others.

Mentions: The architecture of the self-powered system is illustrated in Fig. 1. It consists of two components, a TEG and an ACTFEL lamp. Here two types of TEGs are employed. They represent the two basic operating modes of the TEG17. The square-shaped TEG shown in Fig. 1a relies on the contact mode (Detailed fabrication process is provided in Methods), in which reciprocating pressing force perpendicular to the device results in pulsed electric output voltage and current. The detailed electricity-generating process was described in previous reports18. The disc-shaped TEG pictured in Fig. 1b has a stator-rotator structure, which belongs to the category of the sliding mode (Detailed fabrication process is provided in Methods). Continuous relative rotation between the stator and the rotator produces regularly alternating output current13. The stacked structure of the ACTFEL lamp is diagramed in Fig. 1c. On a glass substrate, four layers are fabricated in sequence, including an ITO electrode layer, a phosphor layer, a dielectric layer and a silver back electrode layer. The details of the structure are revealed in the SEM cross-sectional view (Fig. 1d,e). Complete fabrication process of the ACTFEL lamp is provided in Methods.
