| Popis: | Tin disulfide nanosheets (SnS2 NSs), belonging to a new family of layered metal dichalcogenides, have evoked considerable attention in multidisplinary scientific applications because of their high electron mobility, excellent chemical stability, and wide accessibility to optoelectronic devices. However, despite the prediction of SnS2 to possess excellent piezoelectricity, only very few attempts have been made to investigate the electromechanical characterisitcs of SnS2. Herein, we report the experimental investigation of the intrinsic piezoelectricity of SnS2 NSs, which were synthesized with a facile chemical vapor deposition (CVD) method. The prominent inverse piezoelectricity of SnS2 NSs was measured via piezoresponse force microscpoy (PFM). To further evaluate the piezoelectric performance, SnS2 NSs were integrated into a piezoelectric nanogenerator (PENG) device to display the energy harvesting and active sensing capabilities. Most importantly, the SnS2 PENG device was utilized to explore the synchronous human-robot control of a smart sign language system, which demonstrates great potential for the future applications in human-machine interface and enabling sensing technology. |
