“…However, widespread usage of these techniques is likely to be shadowed by possible limitations, including structure complexity, requirement of sophisticated materials, and reliance on external power source. Recently, triboelectric nanogenerator [4][5][6][7][8][9][10], creative invention based on the coupling of the universally known contact electrification effect and electrostatic induction, has been extensively explored to establish cost-effective and robust self-powered sensing systems, including but not limited to vibration sensor [11], motion sensor [12], acoustic sensor [13], biosensor [14], displacement vector sensor [15], acceleration sensor [16], wind vector sensor [17], tactile sensor [18], tracking sensor [19], and chemical sensor [20,21]. Here, based on the previous research of harvesting water wave energy with TENG [22], we, for the first time, introduce a new principle in PH detection by fabricating a triboelectric sensor.…”

A self-powered, sliding electrification based triboelectric sensor was developed for detecting PH value from a periodic contact/separation motion. This innovative, cost-effective, simply designed sensor is composed of a fluorinated ethylene propylene thin film and an array of electrodes underneath. The operation of the TENG (triboelectric nanogenerator) sensor relies on a repetitive emerging-submerging process with traveling solution waves, in which the coupling between triboelectrification and electrostatic induction gives rise to alternating flows of electrons between electrodes. On the basis of coupling effect between triboelectrification and electrostatic induction, the sensor generates electric output signals which are associated with PH value. Experimental results show that the output voltage of the TENG sensor increases with the increasing PH value, which indicate that the PH value of different solution can be real-time monitored. This work not only demonstrates a new principle in the field of PH value measurement but also greatly expands the applicability of triboelectric nanogenerator (TENG) as self-powered sensors.

“…They reported a checker-like TENG with interdigitated electrodes and used a sliding contact between PET and PTFE as a source for the triboelectric charge generation. Next, Xia et al has redesigned the electrodes by introducing a new honeycomb-like three-electrodes structure [21]. Recently, a similar idea to the checker-like TENG has been proposed by Ma et al They developed a biomimetic fish-scale-like TENG and manufactured based on PET film and PTFE sheet [22].…”

Textile-based triboelectric nanogenerator with alternating positive and negative freestanding woven structure for harvesting sliding energy in all directions

et al. 2022

A novel textile-based triboelectric nanogenerator (TENG) with woven structure operating in freestanding triboelectric-layer mode, defined as a woven-TENG, has been developed. Whereas most woven-structured TENGs operate in contact-separation mode and consist of one type of triboelectric material, this woven-TENG comprises woven electrodes and woven strips of positive and negative triboelectric material, which form a checker-like pattern over the electrodes with matching periodicity. The implementation of the positive and negative triboelectric material significantly improves the performance of the woven-TENG. Furthermore, in contrast to the conventional grating-structured and woven-structured TENG, which are designed to operate only in one moving direction, this new design also allows the woven-TENG to harvest energy from allplanar directions of movement. The woven-TENG with woven strips of nylon and polytetrafluoroethylenevinyl (PTFE) fabric can generate a root mean square (RMS) open-circuit voltage of 62.9 V, an RMS short-circuit current of 1.77 µA and a maximum RMS power of 34.8 µW at a load resistance of 50 MΩ, a mechanical oscillation of 2 Hz and a contact force of 5 N. This corresponds to a maximum RMS power density of 5.43 mW/m 2 .

“…The overall capacitance variations can be significantly amplified by synergizing all the energy generation cells with small air gaps, making the proposed h-TENG extremely sensitive to external perturbations. • The honeycomb-structured TENG proposed in this research adopts a novel 3-D hierarchical structure based on multilayer PET/AgNWs/FEP composites compared with the previous TENGs with in-plane honeycomb patterns [70][71][72]. These parallel-connected and deformable units can significantly boost capacitance variations and enhance the overall performance of the device.…”

Flexible, compact, lightweight and sustainable power sources are indispensable for modern wearable and personal electronics and small-unmanned aerial vehicles (UAVs). Hierarchical honeycomb has the unique merits of compact mesostructures, excellent energy absorption properties and considerable weight to strength ratios. Herein, a honeycomb-inspired triboelectric nanogenerator (h-TENG) is proposed for biomechanical and UAV morphing wing energy harvesting based on contact triboelectrification wavy surface of cellular honeycomb structure. The wavy surface comprises a multilayered thin film structure (combining polyethylene terephthalate, silver nanowires and fluorinated ethylene propylene) fabricated through high-temperature thermoplastic molding and wafer-level bonding process. With superior synchronization of large amounts of energy generation units with honeycomb cells, the manufactured h-TENG prototype produces the maximum instantaneous open-circuit voltage, short-circuit current and output power of 1207 V, 68.5 μA and 12.4 mW, respectively, corresponding to a remarkable peak power density of 0.275 mW cm−3 (or 2.48 mW g−1) under hand pressing excitations. Attributed to the excellent elastic property of self-rebounding honeycomb structure, the flexible and transparent h-TENG can be easily pressed, bent and integrated into shoes for real-time insole plantar pressure mapping. The lightweight and compact h-TENG is further installed into a morphing wing of small UAVs for efficiently converting the flapping energy of ailerons into electricity for the first time. This research demonstrates this new conceptualizing single h-TENG device's versatility and viability for broad-range real-world application scenarios.
