“…The surface area improvement on patterned/textured TENG and the correlation with output performance were explored in previous studies. [ 36,37 ] The approximate surface area improvement after laser patterning was calculated with the aid of Autodesk‐Fusion 360 software. The area of the pristine sample (3.5 mm × 3.5 mm) was compared with the best‐performing TENG's FEP surface area by replicating the pattern, as shown in Figure S5, Supporting Information.…”

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.

“…The selected opposite materials were as follows: TPU and PET as tribopositive polymers and Ecoflex and PI as tribonegative polymers. [55][56][57][58][59] The mechanical properties of the selected materials were also considered in addition to their triboelectric property. Consequently, the opposite chosen materials can be also divided into two categories: nonstretchable (i.e., PET and PI), and stretchable (i.e., Ecoflex and TPU).…”

Developing energy harvesting devices is crucial to mitigate the dependence on conventional and rigid batteries in wearable electronics, ensuring their autonomous operation. Nanogenerators offer a cost‐effective solution for enabling continuous operation of wearable electronics. Herein, this study proposes a novel strategy that combines freeze‐casting, freeze‐drying, and printing technologies to fabricate a fully printed triboelectric nanogenerator (TENG) based on polyvinylidene fluorid‐etrifluoroethylene P(VDF‐TrFE) porous aerogel. First, the effects of porosity and poling on the stretchability and energy harvesting capabilities of P(VDF‐TrFE) are investigated, conducting a comprehensive analysis of this porous structure's impact on the mechanical, ferroelectric, and triboelectric properties compared to solid P(VDF‐TrFE) films. The results demonstrate that structural modification of P(VDF‐TrFE) significantly enhances stretchability increasing it from 7.7% (solid) to 66.4% (porous). This modification enhances output voltage by 66% and generated charges by 48% for non‐poled P(VDF‐TrFE) porous aerogel films compared to their non‐poled solid counterparts. Then, a fully printed TENG is demonstrated using stretchable materials, exhibiting a peak power of 62.8 mW m−2 and an average power of 9.9 mW m−2 over 100 tapping cycles at 0.75 Hz. It can illuminate light‐emitting diodes (LEDs) through the harvesting of mechanical energy from human motion. This study provides a significant advance in the development of energy harvesting devices.
