“…The device was entirely fabricated using stretchable materials, including TPU substrates, Ecoflex, and P(VDF-TrFE) porous aerogel as active layers, and electrodes fabricated with stretchable silver ink. [66][67][68] This composition inherently grants the device stretchability, utilizing the mechanical characteristics of these materials to ensure overall flexibility and resistance to mechanical deformations. The viability of the use of the integrated TENG for energy harvesting was further studied by applying a periodic compressive force of 63.4 ± 7.2 N at 0.75 Hz.…”

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.

Additive manufacturing is an emerging technology with the advantage of less wastage, fast prototyping with customized designing suitable for a wide range of applications. Three‐dimensional (3D) printing is one of the types of additive manufacturing and various polymers are explored for 3D printing applications. Thermoplastic polyurethane (TPU) is a versatile material that has gained increasing attention in 3D printing applications due to its unique combination of mechanical, thermal, and chemical properties. This review paper provides an overview of the current state‐of‐the‐art in TPU‐based 3D printing, including its characteristics, processing techniques, and mainly its applications. Extensive studies are done in TPU with fused deposition modeling (FDM), multi‐jet fusion (MJF), and selective laser sintering (SLS). The elasticity and flexibility, layer adhesion, tensile strength, and support structure are the parameters that decide the suitability of FDM, SLS, and MJF for TPU 3D printing. The infill density, modification of processing parameters, use of sacrificial materials, addition of perforations or channels, varying the particle size, using a mixture of powders, and so forth. leads to develop the porous structure in the final product. In addition, we have studied blends of TPU with other polymers like acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA), as well as fiber‐reinforced TPU composites for 3D printing applications.

“…In addition, other micro-technologies [ 17 , 18 ], such as 3D printing [ 7 ] and SU-8 [ 17 ], have been successfully used for fabricating dual-polarized antennas or complex OMT structures. Three-dimensional printing [ 19 , 20 , 21 ] can manufacture extremely complex structures from monomers, which is advantageous for symmetric OMT, but the rough precision is not suitable for millimeter wave antenna processing. At the same time, these precision manufacturing technologies are accompanied by high manufacturing costs.…”

A wideband multi-polarized square-horn antenna based on an orthogonal mode transducer (OMT) is developed for working in the whole W-band in this paper. The designed antenna is capable of radiating multiple polarization modes as horizontal polarization (HP) and vertical polarization (VP) when as single-port excitation and left-handed circular polarization (LHCP) and right-handed circular polarization (RHCP) when as dual-port excitation, owing to the characteristic of the OMT with the transmitting of orthogonally polarized waves. A CNC-layered fabrication approach is proposed, which means that the antenna prototype integrating with a Boifot-type OMT, turning waveguide, twisting waveguide and phase shifter is divided into three layers along the vertical direction to be fabricated based on computerized numerical control (CNC) technology. In the design, the turning waveguide and twisting waveguide are employed to achieve plane consistency of the antenna branch ports. Furthermore, a phase shifter is designed to compensate the orthogonally polarized waves, which can keep the phase of the orthogonally polarized waves consistent in a wideband frequency range from 75 GHz to 110 GHz. A prototype is fabricated and measured to verify the performance of the proposed multi-polarization antenna, and the measured results agree well with the simulation ones. In the whole W-band, the value of return loss is better than 10 dB of all polarization modes, and the value of AR of the LHCP and RHCP is below 3.5 dB. The maximum gain of the antenna reaches up to 18.8 dBi at 110 GHz. In addition, regarding the layered structure, the possible layered assembly error analysis is discussed, which verifies the feasibility of the layered machining for this antenna.
