Harvesting thermoelectric energy mainly relies on the Seebeck effect that utilizes a temperature difference between two ends of device for driving diffusion charge carriers. However, in an environment is spatially uniform without gradient, pyroelectric has to be choice, which based spontaneous polarization certain anisotropic solids due time-dependent variation. Using this effect, we experimentally demonstrate first application ZnO nanowire arrays converting heat into electricity. The...
Smart garments for monitoring physiological and biomechanical signals of the human body are key sensors personalized healthcare. However, they typically require bulky battery packs or have to be plugged into an electric plug in order operate. Thus, a smart shirt that can extract energy from motions run body-worn healthcare is particularly desirable. Here, we demonstrated metal-free fiber-based generator (FBG) via simple, cost-effective method by using commodity cotton threads,...
A self-powered pressure-sensor matrix based on ZnS:Mn particles for more-secure signature collection is presented, by recording both handwritten signatures and the pressure applied signees. This large-area, flexible sensor can map 2D distributions in situ, either statically or dynamically, piezophotonic effect proposed to initiate mechanoluminescence process once a dynamic mechanical strain applied.
Abstract Due to polarization of ions in crystals with noncentral symmetry, such as ZnO, GaN, and InN, a piezoelectric potential (piezopotential) is created the crystal when stress applied. Electronics fabricated using inner‐crystal piezopotential gate voltage tune or control charge transport behavior across metal/semiconductor interface p–n junction are called piezotronics. This different from basic design complimentary metal oxide semiconductor (CMOS) field‐effect transistors has...
We demonstrate the piezoelectric effect on responsivity of a metal−semiconductor−metal ZnO micro-/nanowire photodetector. The photodetector is respectively enhanced by 530%, 190%, 9%, and 15% upon 4.1 pW, 120.0 nW, 180.4 nW UV light illumination onto wire introducing −0.36% compressive strain in wire, which effectively tuned Schottky barrier height at contact produced local piezopotential. After systematic study change with tuning excitation intensity, an in-depth understanding provided...
An electric field built inside a crystal was proposed to enhance photoinduced carrier separation for improving photocatalytic property of semiconductor photocatalysts. However, static built-in can easily be saturated by the free carriers due electrostatic screening, and enhancement photocatalysis, thus, is halted. To overcome this problem, here, we propose sonophotocatalysis based on new hybrid photocatalyst, which combines ferroelectric nanocrystals (BaTiO3) nanoparticles (Ag2O) form an...
We demonstrate the first self-powered system driven by a nanogenerator (NG) that works wirelessly and independently for long-distance data transmission. The NG was made of free cantilever beam consisted five-layer structure: flexible polymer substrate, ZnO nanowire textured films on its top bottom surfaces, electrodes surfaces. When it strained to 0.12% at strain rate 3.56% S–1, measured output voltage reached 10 V, current exceeded 0.6 μA (corresponding power density mW/cm3). A built up...
Energy generation and energy storage are two distinct processes that usually accomplished using separated units designed on the basis of different physical principles, such as piezoelectric nanogenerator Li-ion battery; former converts mechanical into electricity, latter stores electric chemical energy. Here, we introduce a fundamental mechanism directly hybridizes one, in which is converted simultaneously stored without going through intermediate step first converting electricity. By...

Integrated optical isolators have been a longstanding challenge for photonic integrated circuits (PICs).An ideal isolator PIC should be made by monolithic process, small footprint, exhibit broadband and polarization-diverse operation, compatible with multiple materials platforms.Despite significant progress, the reported so far do not meet all of these requirements.In this paper we present monolithically magneto-optical on silicon nitride (SiN) platforms operating both TE TM modes...
Abstract The availability of graphene and other two-dimensional (2D) materials on a wide range substrates forms the basis for large-area applications, such as integration with silicon-based technologies, which requires silicon outperforming carrier mobilities. However, 2D were only produced limited archetypal by chemical vapor deposition approaches. Reliable after-growth transfer techniques, that do not produce cracks, contamination, wrinkles, are critical layering onto arbitrary substrates....
