(1 of 9)triboelectric nanogenerator (TENG), based on the coupling of triboelectrification and electrostatic induction, [5][6][7][8][9][10] has been proved as a cost-effective, simple, and efficient technique, which can directly convert mechanical energy such as wind flows, ocean waves and human motions into electric energy. [11][12][13][14][15][16][17][18][19][20] Recently, various strategies have been reported to improve the performance of TENG, such as selection of suitable triboelectric materials, [21] charge injection, [22] control of morphology, [23] and structural optimization. [24] Of all the above mentioned methods, the selection of the material is the most effective way to fundamentally improve the performance of the TENG via the increase of the surface charge density, but it is usually confined to some conventional materials from triboelectric series. Hu's group had demonstrated that the output performance has a close relationship with the dielectric constant of the tribomaterial. [25] In addition, for the TENG-based energy harvesting and self-powered applications in open environment, environmental factors, such as humidity, have a great influence on the performance of TENG. [20,26] The output performance of TENG would be drastically degraded by humidity due to formation of a water layer on the surface of the triboelectric materials which deplete the induced charges. Thus, it is still a challenge to design a novel TENG material with excellent performance under varying environments, such as high humidity.Metal organic frameworks (MOFs) are an intriguing class of crystalline materials that comprises inorganic metal ions (components of nodes) and organic ligands (structural linkers) via coordination chemistry. [27,28] Owing to large internal surface areas and extended nanoscale porosity, MOFs have been widely studied as candidate materials for applications in chemical separations, [29] gas storage, [30] catalysis, [31] sensing, [32] and drug delivery. [33] HKUST-1 (Cu 3 (BTC) 2 , (BTC = 1,3,5-benzenetricarboxylate or trimesate)) is a very well-studied and stable MOF, which consists of Cu ions and benzene tricarboxylate (BTC) as a linker. Recently, experimental results have shown that the dielectric property of HKUST-1 film is highly dependent on the relative humidity (RH). [34] Till now, no experimental reports on the triboelectric property based on MOF matericals have been reported yet.In this paper, we designed a novel humidity-resistive TENG based on nanocomposite film made of HKUST-1 and polydimethylsiloxane (PDMS). HKUST-1 has poor conductivity due to the insulating nature of organic ligands along with d-orbital participation of metal ions in coordination bonds With its light weight, low cost, and high efficiency, the triboelectric nanogenerator (TENG) is considered a sustainable and renewable energy source for selfpowered or mobile electronics. However, the performance of TENG is seriously affected by humid environment. Here, for the first time, TENG with improved performance under high humidity is o...

“…The SETEGs with 0.55 mm glass were cyclically tested under different contact forces, frequencies, spacers. There are two main reasons that enhance the electric output of the contact mode glass based TEG under higher contact forces according to our previous work [14], which are the increase of the contact area and the total capacitance of the TEG [16]. The capacitance increase of the PDMS part in the TEG is the primary reason that results in the total capacitance increase of the TEG, because glass is a rigid material and higher contact force will only compress the PDMS layer, leading to a smaller thickness, which means a larger flat panel capacity of the PDMS part.…”

“…For the SETEG, the PDMS part has not electrically linked to the TEG, so the total capacity of the TEG actually remains almost unchanged. Only the increased contact area enhances the electric output performance under higher contact force, and that's the reason why the electric output improvement of the glass based SETEG under higher contact force was not as good as that of glass based contact mode TEG [14]. Hz, and the short circuit current shows the similar trend, gradually increasing from 1.9 μA (1 Hz) to 7 μA (5 Hz).…”

“…A dynamic fatigue tester (Popwill Model YPS-1) was utilized to control the cyclic contact force, frequency and spacer between the two TEG electrodes, which is the same as the experimental setup in our previous work [14]. The voltage and current outputs were collected using an oscilloscope (Tektronix MDO3022) and a picometer (Keysight B2981A), respectively.…”

A glass-based single electrode triboelectric generator (SETEG) is developed with polydimethylsiloxane (PDMS) as the negative material. Its performance under different contact forces, frequencies and spacers is investigated in detail. The SETEGs have higher electric output under higher contact force, frequency and spacer, and show better performance with a thinner glass layer at lower humidity condition. An open circuit voltage, short circuit current and power up to 318 V, 8.3 μA and 427 μW are obtained for a SETEG of 5×5 cm 2 size. Based on the study, a tracking sensor array consisting of nine 5×5 mm 2 SETEGs is proposed and developed. A LabVIEW-based automatic measurement system is also developed to record, process and display the real-time output voltages of the sensing array. Results show that an output voltage up to 4 V can be easily generated when a PDMS-covered stylus touches/slides the sensor array, and the output voltages from different sensors are independent from each other. This work demonstrates the great application potential of the SETEGs sensor array for self-powered detection, tracking or monitoring motion or a touch of a stylus or some objects, thus would be very useful for touch screen display, handheld tracking device, domestic security, traffic monitoring etc.

Recently, a new class of portable self‐powered electronic systems is developed that utilizes highly efficient hybrid nanogenerators that convert mechanical energy into electricity to power various sensors/small‐scale electronics. This article proposes aluminum titanate (Al2TiO5) microparticles (AlT MPs) loaded poly‐glucosamine (PGA) composite film‐based high‐performance hybrid nanogenerators (HNG) employed as a self‐powered sensor for signal indication and as an intruder sensing platform. Initially, AlT MPs are synthesized and various concentrations are loaded into PGA. HNGs are fabricated using composite films/ polydimethylsiloxane, and Al as the positive/negative triboelectric layers and electrode film, respectively. The fabricated HNGs operate in the contact‐separation mode and their produced electrical outputs are comparatively studied to determine the most suitable AlT concentration. The optimized HNG produces the highest electrical output of ≈211 V, ≈5.5 µA, and 79.5 µC/m2. The optimized HNG is employed as a biomechanical energy harvester to scavenge energy from various biomechanical movements and power portable electronics utilizing the developed highly efficient power management circuit. Thereafter, multiple HNGs are utilized to fabricate a self‐powered wireless sensing system and real‐time intruder sensing platform. The proposed highly efficient HNG‐based self‐powered wireless sensing platform is a promising technology that can be used on a large scale in various applications.
