“…Recently, laser technology has attracted substantial attention based on the advantages of novel accuracy and time-efficient properties. Laser-induced devices have been extensively studied, − and numerous TENG studies using laser ablation also have been conducted to enhance the output performance of the TENG device. − Among the proposed approaches, forming a surface structure by a molding/demolding process is popular. − This outstanding method offers the advantages of enhanced electrical outputs and accurate scribing of the desired morphology. However, the fabrication process of casting polydimethylsiloxane (PDMS) consumes a considerable amount of time, which spends roughly 2 h. Besides, the molding/demolding method requires additional technical and material efforts in the process to fabricate the master mold and to demold a rough structured triboelectric layer.…”

Triboelectric nanogenerators (TENGs) recently have emerged as applicable and eco-friendly harvesting devices. Numerous studies have been actively conducted to fabricate a flexible and robust TENG with high-output performance. Herein, a film-sponge-coupled TENG (FS-TENG) is proposed using direct ultraviolet laser ablation, as a method for surface modification of a polyimide (PI) film. This state-of-the-art method has advantages of accuracy as well as time efficiency in creating the pattern on the surface; thus, the pre-designed patterns can be precisely constructed within only a minute. In the laser-ablated PI film, the structural design and chemical modification on the surface are investigated related to the triboelectric output performance. Thereafter, a sponge is fabricated based on non-woven polyamide and silicone rubber, which can fully contact with the micro-/nano-scaled structure on the surface of the PI film. After an optimization, the FS-TENG exhibits 48.19 V of open-circuit voltage and 1.243 μA of short-circuit current, which shows approximately 3 times enhanced electric performance compared to the FS-TENG using a pristine PI film. The FS-TENG device demonstrates its robustness through both mechanical stress and flexible stress by showing less than 5% degradation after 50,000 cycles. On the basis of the high flexibility and stability of the FS-TENG, a self-powered scoreboard is successfully developed for lighting a scoreboard in a soccer field. This feasible lighting system can be operated by harvesting the kinetic energy of a soccer player without an additional power source. The novel FS-TENG, thus, provides remarkable potential for a self-powered indoor harvesting system.

“…A combination of pulsed laser‐assisted patterning on aluminum surface and chemical etching on PTFE surface produced approximately double the voltage compared to the pristine device. [ 31 ] Ultrafast laser direct patterning on the triboelectric surfaces was able to produce significant enhancement in the electrical output. [ 22,32 ] Most of the studies were focused on texturing on the triboelectric contact surfaces, and there is need to explore the patterning effect on the electrode of the dielectric surface.…”

Triboelectric nanogenerators (TENGs) are promising cost‐effective energy harvesters useful to scavenge vibration or mechanical movements from various domains. Ranging from condition monitoring of machines to motion sensing of humans, its applications are enormous in the internet of things scenario. Enhancing the performance of small‐sized TENGs is of great demand, and pulsed laser‐assisted texturing is an efficient and proven method to enhance the output of energy harvesters. This work studies simultaneous laser patterning of fluorinated ethylene propylene (FEP) dielectric material and the underneath copper electrode with three different wavelengths (355, 532, and 1064 nm) of the Nd3+:YAG laser and the device's electrical performance is analyzed. The maximum enhancement is observed in the case of 355 nm laser‐assisted patterning on FEP and Cu electrode with a laser fluence of 10 J cm−2. The improvement is least in the case of 1064 nm laser‐assisted patterning. Laser patterning on the underlying electrode with this new approach is able to produce an enhancement in the TENG output. However, patterning on the FEP top surface is critical in the process.
