possess pyroelectric properties, including the leaves of the palm-like plant Encephalartos. [4] While the physiological implications of pyroelectricity in plants and other biomaterials are still poorly understood, [4,5] the effect can already be utilized in artificial devices for applications including light detection [2d,6] and energy harvesting. [3,7] Pyroelectric polymers have attracted considerable attention owing to their mechanical flexibility, easy processing, and low cost. [4,5] While there are a number of pyroelectric polymers, such as poly(vinylchloride) and Nylon 11, poly(vinylidene fluoride) and its copolymer poly(vinylidenefluoride-cotrifluoroethylene) (P(VDF-TRFE)) are particularly promising due to high pyroelectric coefficients and good chemical stability. [2a,c,d,8] Typical application areas for these polymers include heat sensing, thermal imaging, and fire alarms. [2a] In addition, these polymers have been significantly explored based on their piezoelectric properties to harvest mechanical energy. [3,9] Their combination with plasmonic nanostructures was only recently reported, for laser-based patterned phase-control of ferroelectric polymers. [10] However, plasmonic heating was, to our knowledge, not previously investigated for pyroelectric energy harvesting.Here, we present a concept that converts temporal fluctuations in sunlight to electrical energy. The device combines a plasmonic metasurface consisting of gold nanodisks with a thin organic P(VDF-TrFE) copolymer film. The plasmonic nanostructures strongly absorb light through resonant excitation of plasmons (collective charge oscillations), which leads to local heating of both the nanostructure and the surrounding environment. [11] Such light-induced plasmonic heating can enable a wide range of applications, including solar-powered autoclaving, [12] plasmon-driven thermophoresis, [13] seawater catalysis, [14] plasmonic-thermoelectric light detection, [15] and desalination concepts. [14] In our hybrid plasmonic-pyroelectric device (referred to as hybrid device below), plasmonic heating of a gold nanodisk array modulates the temperature of a pyroelectric polymer. The polymer then converts these temperaturechanges to electrical signals through the pyroelectric effect.We demonstrate the concept by designing a device that powers an external load connected to the hybrid device, and by characterizing its performance in detail. Combined optical and thermal simulations of the hybrid device are in agreement with State-of-the-art solar energy harvesting systems based on photovoltaic technology require constant illumination for optimal operation. However, weather conditions and solar illumination tend to fluctuate. Here, a device is presented that extracts electrical energy from such light fluctuations. The concept combines light-induced heating of gold nanodisks (acting as plasmonic optical nanoantennas), and an organic pyroelectric copolymer film (poly(vinylidenefluoride-co-trifluoroethylene)), that converts temperature changes into electrical sig...

“…Recently, a new type of technology, the triboelectric nanogenerator (TENG), has been also demonstrated to establish a platform for developing self-powered sensor systems and flexible/wearable electronics to harvest mechanical energy from the surrounding environment into electricity 8 – 10 . The working principle of the TENG is a coupling of the triboelectric effect and electrostatic induction, and charge transfer occurs when two different frictional materials with opposite triboelectric polarities come in contact with each other, generating opposite and equivalent charges at the interface 11 – 13 .…”

The triboelectric nanogenerator (TENG) has great potential in the field of self-powered sensor fabrication. Recently, smart electronic devices and movement monitoring sensors have attracted the attention of scientists because of their application in the field of artificial intelligence. In this article, a TENG finger movement monitoring, self-powered sensor has been designed and analysed. Under finger movements, the TENG realizes the contact and separation to convert the mechanical energy into electrical signal. A pulse output current of 7.8 μA is generated by the bending and straightening motions of the artificial finger. The optimal output power can be realized when the external resistance is approximately 30 MΩ. The random motions of the finger are detected by the system with multiple TENG sensors in series. This type of flexible and self-powered sensor has potential applications in artificial intelligence and robot manufacturing.

“…Usually, the conversion and storage of energy are two different processes. For example, piezoelectric nanogenerators and photovoltaic cells convert mechanical and solar energy, respectively, into electrical energy that is stored in a different physical storage unit such as a capacitor or lithium ion battery for future use. However, recently researchers were interested in the fabrication of a hybrid system that is a self‐charging power cell able to harvest electrical energy from renewable energy resources and store it …”

A simple photovoltaically self‐charging energy‐storage system (PSESS) has been fabricated as an effective solar energy‐storage power cell. The PSESS is capable of the in situ storage of visible light energy in the form of electrical energy. The PSESS is assembled on a photoelectrode (fluorine‐doped tin oxide) that contained a dye‐sensitized and hole‐trapping phenosafranine–polyvinylpyrrolidone film in association with an electroactive and highly dielectric chlorochalcone–polyvinylidene fluoride (PVDF) film, in which photogenerated electrons are stored. Here, chlorochalcone particles act as a catalytic agent for electroactive β crystal nucleation, visible‐light emission, and the improved dielectric value of the composite thin films. A proportion of 85 % electroactive β phase nucleation and a high dielectric constant (≈60) are achieved by incorporating 20 mass % chlorochalcone in PVDF. The self‐charging capability of the PSESS was verified under a light illumination intensity of 110 mW cm−2. The PSESS was charged up to 0.95 V under light illumination. Moreover, the device wass discharged with a constant current density 1.25 mA g−1 for a long time (≈560 min) after the light was switched off. The photogenerated energy and charge density of the PSESS are approximately 5.25 mWh g−1 and 42 C g−1, respectively. The maximum capacitance attained under the light illumination is approximately 44 F g−1, which is many times greater than two‐electrode self‐charged photovoltaic cells reported previously. A blue light‐emitting diode can be driven by using the PSESSs as a power bank.
