In recent decades, nanogenerators based on several techniques such as triboelectric effects, piezoelectric effects, or other mechanisms have experienced great developments. The nanoenergy generated by nanogenerators is supposed to be used to overcome the problem of energy supply problems for portable electronics and to be applied to self-powered microsystems including sensors, actuators, integrated circuits, power sources, and so on. Researchers made many attempts to achieve a good solution and have performed many explorations. Massive efforts have been devoted to developing self-powered electronics, such as self-powered communication devices, self-powered human–machine interfaces, and self-powered sensors. To take full advantage of nanoenergy, we need to review the existing applications, look for similarities and differences, and then explore the ways of achieving various self-powered systems with better performance. In this review, the methods of applying nanogenerators in specific circumstances are studied. The applications of nanogenerators are classified into two categories, direct utilization and indirect utilization, according to whether a treatment process is needed. We expect to offer a line of thought for future research on self-powered electronics.

A Comprehensive Review on Piezoelectric Polymeric and Ceramic Nanogenerators

2022

View full text Add to dashboard Cite

With the increasing concerns over global warming and the growing demands for electricity, many researchers have considered renewable and sustainable resources for electricity/power generation. [1] Photovoltaics, thermoelectric, and electromagnetic induction are among the well-established technologies for electricity generation. [2] Mechanical energy is one of the most abundant and available resources that can be harvested to generate electricity. For example, mechanical energy is available in the form of human body motion and mechanical vibration. [3][4][5][6] Piezoelectric and triboelectric nanogenerators have both been used for mechanical energy harvesting. In triboelectric nanogenerators, electrical energy originates mainly from friction or temporary contact of two different layers. However, a wide range of deformation modes like bending, stretching, and vibration can generate electricity using piezoelectric nanogenerators (PNGs). The working mechanisms of PNGs are typically easier than triboelectric nanogenerators. [7] In addition, improving electrical output and reproducibility of triboelectric nanogenerators are still challenges. [8] The use of ferroelectric materials is a promising choice for energy harvesting. Ferroelectric materials show both piezoelectric (generation of electrical power from mechanical oscillation) and pyroelectric (generation of electricity from temperature fluctuation) properties. [9,10] Piezoelectric property offers conversion of mechanical energy to electricity. By applying mechanical stress, dipole momentum forms, leading to spontaneous polarization. Consequently, the electric current flows through the piezoelectric materials as a result of charge accumulation. [11] A wide range of piezoelectric materials is used as PNGs. Piezoelectric materials can be categorized into ceramics, polymers, and piezoelectret polymers. Materials with perovskite or wurtzite nanostructures show piezoelectric properties because their crystals are noncentral symmetry. Ceramics with perovskite

Polymer nanofibers are widely adopted in energy harvesting and pressure sensing applications owing to the large contact area and inherent compressibility. Herein, a high-performance triboelectric nanogenerator (TENG) based on 2D siloxene-polyvinylidene fluoride (S-PVDF) composite nanofibrous membrane is newly evaluated. Through proper ratio optimization and facile electrospinning, the fabricated membrane shows significant improvement in dielectric property, electronegativity, and compressibility. The TENG comprising S-PVDF membrane and Nylon 6/6 can deliver an excellent power density of 13.25 W m −2 (f ≈ 5 Hz) and easily operates low-power electronics and Internet of things (IoTs). In addition, the excellent compressibility of membrane extends its applicability to self-powered simultaneous detection of dynamic and static pressure, which is investigated by developing a hybrid pressure sensor (HPS) through effective integration of TENG and a capacitive pressure sensor. The HPS shows an excellent dynamic (12.062 V kPa −1 at (<3 kPa) and 2.58 V kPa −1 at (3-25 kPa)) and static (25.07 mV kPa −1 at (<3 kPa) and 5.96 mV kPa −1 at (3-25 kPa)) pressure sensitivities, respectively. Furthermore, a 2 × 2 HPS array tested and analyzed for multiple users using artificial intelligence significantly improves the accuracy (98%). Remarkable energy harvesting performance and greater accuracy of the HPS manifests better preferences for future self-powered IoT and smart tactile-based user authentication systems.
