“…We have shown how the output voltage changes with the increment value of mass of starch gel under the stroke time of 40 ms in Figure f, where i-TENG gives the lowest output voltage and it increases to 280 V for c-TENG which was developed using SGC 15 and nitrile rubber and the output voltage decreases again with a higher amount of starch gel. The lower concentration of starch gel promotes charge transfer to the surface of counter material and after the optimum ratio, the transfer of charge gets lowered. , That is why SGC 5 to SGC 15 we have an increasing value of voltage, and for SGC 20 the voltage level gets reduced. The reason for the higher output of c-TENG compared to i-TENG may be attributed to the increased electronegativity of SGC, and in consequence, the position of SGC shifts to a more negative side compared to intrinsic silicone foam in a typical triboelectric series.…”

“…Among the many strategies, people are currently interested in enhancing the electrical output and sensitivity of TENG by the incorporation of other materials into the well-known polymeric tribo materials. In recent years, some interesting reports based on composites have been published using the doping materials such as perovskite material (BaTiO 3 ) in polydimethylsiloxane (PDMS), K 0.5 Na 0.5 NbO 3 and polyvinylidene fluoride (PVDF), 2D nanomaterial (V 2 CT x ) in silicone solutions, covalent organic framework in poly(vinyl alcohol) (PVA), metal organic framework in PDMS, different coordinated polymers in PVDF, and biomaterial lignin in PVA. − …”

Starch is a material of wide research interest across various disciplines to understand its nature under different circumstances. Herein, we report corn starch gel as a tribo material whose incorporation into silicone foam can enhance the electrical output of a triboelectric nanogenerator (TENG) over 100% compared to the output of a TENG developed using intrinsic silicone foam. The study is carried out by varying the incorporation of different mass ratios of corn starch gel into silicone foam and prepared a starch gel composite (SGC). The composite material SGC with a mass ratio of 1:1.02 of corn starch gel and silicone foam produces the highest output voltage of ∼280 V compared to the output voltage of 132 V of a TENG developed using intrinsic silicone foam. It delivers a output current of 6.9 μA and a peak power of 897 μW corresponding to a power density of 996 mW/m 2 . Furthermore, the potential of real-time applications of TENG using SGC (c-TENG) has been demonstrated through powering up of light-emitting diodes, charging some commercial capacitors, and healthcare sensing applications. The device is highly stable, as over 15,000 cycles, it gives a constant output voltage of ∼280 V. The enhanced electrical output and stability of the device opens up the possibility of further research in the field of TENG using a composite material of starch for high-voltage self-powered applications.

The utilization of sensors has become indispensable in the advent of an intelligent era characterized by artificial intelligence, 5G communication, big data, and other cutting-edge technologies. Traditional sensors require external power sources or batteries, resulting in a complex sensing system that does not promote the development of sustainable and environmentally friendly applications for health monitoring. In recent years, the electrical output and stability of piezoelectric, triboelectric, thermoelectric, and hybrid nanogenerators have been significantly improved, enabling their widespread role in the development of self-powered sensors. The sensors are capable of performing sensing tasks by converting their own energy, thereby obviating the need for an external power supply. In this paper, we initially explore the operating mechanisms, device materials, and structures of diverse nanogenerators and evaluate their output efficacy. Subsequently, we showcase the latest advancements in self-powered sensor systems, spanning various fields such as biomedical and healthcare, wearable devices, sound monitoring, smart vehicles, environmental monitoring, and smart cities. The paper also explores the future potential of self-powered sensor systems, in addition to discussing their practical applications.

“…[4][5][6] In particular, triboelectric nanogenerators (TENGs) based on the mechanical friction of insulating and organic materials have been evaluated as a practical technology over the last decade because of their ultrahigh output performance, even using straightforward structures. [6][7][8][9][10] The idea has been expanded to semiconducting materials and various liquids based on identifying tribovoltaic effects. [11][12][13] The DOI: 10.1002/aenm.202304206 tribovoltaic effect is more advantageous than conventional TENG devices because of the wide variety of semiconducting materials and the tunability of their properties by doping or producing heterojunctions.…”

Ubiquitous energy harvesting technologies require new types of renewable, sustainable, and clean energy to solve the problems of fossil fuels. Although various nanogenerators have been developed over the last decade, low current density, requirements for complicated management circuits, generation of direct current (DC) outputs, and significant performance degradation under humid atmospheres have been problems limiting practical applications. This paper reports that the tribovoltaic and moisture‐enabled electricity generation effects can be achieved in a layered double hydroxide (LDH) by applying a metal brushing mode. The ZnAl‐LDH shows enhanced tribovoltaic nanogenerator (TVNG) performance even in a high‐humidity environment coupled with the moisture‐enabled electricity generated by the concentration gradient of a water molecule through the interlamellar structures of the LDHs. The spontaneous dissociation of water in the interior of LDHs removes the hole generated by the tribovoltaic effect, allowing high efficiency of an output voltage of 693.38 mV and current density of 65.48 mA m−2 even under low‐applied force (≈3.5 mN) at relative humidity 80%. The proposed TVNG provides a proof of concept for an all‐in‐one device consisting of a generator and capacitor because the LDH reveals a spontaneous charging performance similar to that of a capacitor.
