Abstract:In the era of big data, a large number of sensors undertake the important task of information collection and transmission in the Internet of Things. It is an urgent problem that how to keep these sensors working steadily, consistently and maintenance-freely. Collecting vibration mechanical energy widely distributed in the environment and building a self-energy supply system, which provides a solution to the problem. As a mechanical energy capture technology, Triboelectric Nanogenerator (TENG) has a higher energy conversion efficiency in collecting low-frequency and irregularity vibrational mechanical energy. A contact-separation mode TENG supported by silicone hemispheres is designed and fabricated for vibration mechanical energy generated by walking. The open-circuit voltage peak of the TENG is 348 V and the short-circuit current peak is 7.7 μA at 1 Hz. With a 40 MΩ external resistor, the instantaneous power reaches 265 μW. When integrated with the resin pouring hard board surface, the self-powered luminous floor system can be realized, which can work normally under different human flow conditions. The luminous floor can be used in shopping malls, pedestrian streets, amusement parks and other places.
