A self-powered gas sensor that can actively detect ethanol at room temperature has been realized from a Pt/ZnO nanoarray nanogenerator. Pt nanoparticles are uniformly distributed on the whole surface of ZnO nanowires. The piezoelectric output of Pt/ZnO nanoarrays can act not only as a power source, but also as a response signal to ethanol at room temperature. Upon exposure to dry air and 1500 p...
Piezoelectric nanogenerators are attracting substantial attention due to the environmental constraints and ecological considerations of energy harvesting. However, Achilles' heel majority these is presence toxic compounds or requirement a poling process promote higher piezoelectric effect. Here, self-poled bio-flexible nanogenerator (BF-PNG) designed, based on lead-free biocompatible Ba0.85Ca0....
Abstract As a representative piezoelectric polymer, poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) has been widely used in sensors transducers and actuators. In this paper, gold nanoparticles (AuNPs) are prepared doped into the PVDF-HFP solution to enhance property of electrospun nanowires. The results indicate that proper amounts AuNPs within nanowires can improve phase PVDF-HFP....
By assembling a ZnO nanowire (NW) array based nanogenerator (NG) that is transparent to UV light, we have investigated the performance of the NG by tuning its carrier density and the characteristics of the Schottky barrier at the interface between the metal electrode and the NW. The formation of a Schottky diode at the interface is a must for the effective operation of the NG. UV light not only...
Abstract Over the past decade, piezoelectric nanogenerator have attracted much attention to harvest mechanical energy from abundant resources in nature. Here, ZnS microspheres is prepared by hydrothermal method and core-shell structured PANI/ZnS are synthesized situ polymerization then used as filler for preparation of flexible [P(VDF-HFP)] based nanogenerator. The P(VDF-HFP)/PANI-ZnS Electrosp...
The creation of sustainable power sources for wearable electronics and self-powered systems is a promising direction modern electronics. At the moment, search functional materials with high values piezoelectric coefficient elasticity, as well non-toxicity, underway to generate such sources. In this paper, nitrogen-doped carbon nanotubes (N-CNTs) are considered material nanogenerator capable con...
