NANOGENERATOARE TRIBOELECTRICE -REALIZĂRI RECENTE

Triboelectric nanogenerators represent a promising direction for the realization of very low-power renewable sources of electrical energy, intended for powering portable electronic devices and sensors used in Internet of Things networks. Their attractiveness is due, first of all, to the ability to efficiently convert the kinetic energies specific to a wide variety of ambient vibrational sources, with low frequencies, such as human movement, the movement of waves, wind, acoustic waves, etc., but also to other factors such as low weight and relatively low cost. In this paper, a brief presentation of triboelectric nanogenerators, their operating mechanisms and their structural configurations is given. By way of illustration, some examples of the use of triboelectric nanogenerators in various fields of current interest are presented.
