Název v původním jazyce

A new hybrid piezo/triboelectric SbSeI nanogenerator

Popis výsledku v původním jazyce

In this paper, a compressed antimony selenoiodide (SbSeI)-based hybrid piezo/triboelectric nano-generator for mechanical energy harvesting is presented for the first time. Sonochemically-fabricated SbSeI nanowires were compressed under high pressure (120 MPa) to form a pellet for use as an experimental electrode. Kapton film was utilized as the other electrode. The basic parameters used for the triboelectric nanogenerator (i.e. surface roughness and dielectric permittivity) were thoroughly studied. The effects of distance between the Kapton and SbSeI electrodes, excitation signal shape, and applied force on the output voltage have been examined. The attempt to separate piezoelectric and triboelectric effects in the measured voltage response has been presented. The maximum peak-to-peak voltage value measured for a 50 g structure loaded was 2.71 V for rectangular signal excitation using an electromagnetic shaker with 80 Hz frequency. The prepared device generated a significantly higher voltage per surface area and force unit (15.8 V/(N.cm(2))) in comparison with similar literature reported values for other piezo/triboelectric generators.
