“…Due to this deformation, the interconnect can have a stretchability that does not break, even in tension. Currently, stretchable interconnects are being manufactured using patterns such as serpentine and fractal designs [ 7 , 14 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 ]. The most representative pattern in stretchable interconnects is the former [ 84 , 94 , 102 , 103 , 104 , 105 , 106 , 107 , 108 ], in which two semicircles are repeatedly connected in a straight line.…”

“…A mesh refers to a pattern in which a shape is constantly connected [ 89 ]. The interconnect can be designed with a regular mesh pattern, to improve electrical and optical performance [ 7 , 89 , 90 , 91 , 92 , 93 , 95 ]. Figure 3 c shows meshes of square, hexagonal, zigzag, and serpentine design; the distribution of plastic strain with respect to tension was simulated for these structures [ 89 ]; thus, confirming that the zigzag and serpentine meshes were capable of greater deformation compared to the square and hexagonal meshes.…”

Biology is characterized by smooth, elastic, and nonplanar surfaces; as a consequence, soft electronics that enable interfacing with nonplanar surfaces allow applications that could not be achieved with the rigid and integrated circuits that exist today. Here, we review the latest examples of technologies and methods that can replace elasticity through a structural approach; these approaches can modify mechanical properties, thereby improving performance, while maintaining the existing material integrity. Furthermore, an overview of the recent progress in wave/wrinkle, stretchable interconnect, origami/kirigami, crack, nano/micro, and textile structures is provided. Finally, potential applications and expected developments in soft electronics are discussed.

“…This is a promising application for human health. For example, we could potentially use the MBF/SWCNTs as a thermotherapy pad to cure local hurt, as demonstrated by other researchers (Lan et al 2017;Chen et al 2021). Further, we could utilize the MBF/SWCNTs as a fast water evaporator (Figure S6 in supporting information).…”

Conductive textiles with good flexibility and durability are highly demanded for wearable electronics. However, the common approaches of making conductive textiles requires multi-steps solvent processes, which is tedious and environment unfriendly. Herein, the high-quality single-walled carbon nanotubes (SWCNTs), synthesized by the floating catalyst chemical vapor deposition (FCCVD) method, were direct and dry coated on the melt-blown fabrics (MBFs) recycled from the waste masks with chemical binder-free. The obtained MBF/SWCNTs composites displayed excellent conductivity and flexibility and thus, can be further used as wearable and heatable textiles. The sheet resistance of MBF/SWCNTs composites can be further reduced by gold chloride (AuCl3) doping from 57 to 26 Ω/sq. The electrical-thermal measurement turned out the pristine MBF/SWCNTs composites can reach the surface temperature of ~ 48°C at a low voltage (5 V), while it increased to ~ 110°C after AuCl3 doping at the same voltage. In addition, the AuCl3 doped MBF/SWCNTs film with thickness of ~ 150 µm displays a high electromagnetic interference (EMI) shielding efficiency of 27.1 dB at X-band. Also, the MBF/SWCNTs composites displayed good stability after long-term heating, bending and washing. Our multi-functional MBF/SWCNTs textiles not only demonstrated the reusability of waste masks but also showed great potential applications in EMI and heat management, such as thermotherapy pads and fast water evaporators.

Conductive textiles with good flexibility and durability are highly demanded for wearable electronics. However, the common approaches of making conductive textiles require multi-step solvent processes, which is tedious and environment unfriendly. Herein, the high-quality single-walled carbon nanotubes (SWCNTs), synthesized by the floating catalyst chemical vapor deposition method, were directed and dry coated on the melt-blown fabrics (MBFs) recycled from the waste masks with binder-free chemical. The obtained MBF/SWCNT composites displayed excellent conductivity and flexibility and thus can be further used as wearable and heatable textiles. The sheet resistance of MBF/SWCNT composites can be further reduced by gold chloride (AuCl3) doping from 57 to 26 Ω/sq. The electrical–thermal measurement showed that the pristine MBF/SWCNT composites can reach the surface temperature of ∼48 °C at a low voltage (5 V), whereas it increased to ∼110 °C after AuCl3 doping at the same voltage. In addition, the AuCl3-doped MBF/SWCNT film with a thickness of ∼150 μm displays a high electromagnetic interference shielding efficiency of 27.1 dB at the X-band. Also, the MBF/SWCNT composites displayed good stability after long-term heating, bending, and washing. Our multi-functional MBF/SWCNT textiles not only demonstrated the reusability of waste masks but also showed great potential applications in electromagnetic interference and heat management, such as thermotherapy pads and fast water evaporators.
