Stretchable piezoelectric nanogenerators are highly desirable for power supply of flexible electronics. Piezoelectric composite material is the most effective strategy to render stretchable. However, generated output performance unsatisfactory due low phase proportion. Here we demonstrate a high-performance Pb(Zr0.52Ti0.48)O3 (PZT)-based stretchable nanogenerator (HSPG). The proposed HSPG exhibits excellent with density ∼81.25 μW/cm3, dozens times higher than previously reported results....
Abstract As a new energy harvesting strategy, triboelectric nanogenerators which have broad application prospect in collecting environmental energy, human body mechanical and supplying power for low‐power electronic devices, attracted extensive attention. However, technology challenges still exist the stretchability preparation of some high‐performance materials. In this work, strategy nonmetallic nylon‐modified (NM‐TENGs) is reported. Nylon introduced as high performance friction material...
Aluminum oxide (Al 2 O 3 ) amorphous structure with short-range order and long-range disorder has presented promising applications in optical optoelectronic devices. In this paper, the Al films different thickness were prepared by atomic layer deposition (ALD) technology at 200°C to achieve structure. X-ray diffraction (XRD) energy dispersive spectrum (EDS) results indicated that stable O/Al ratio. The surface topography investigated force microscopy (AFM) showed samples smooth crack-free....
