“…However, in our system, the dielectric layer can increase the average dielectric constant under deformation, preventing a decrease in sensitivity even under large strains. Benefiting from the superior tensile property of the ionogel and MFE, our CPS can operate at ultrahigh tensile strains, surpassing most of the previously reported work. ,,,− …”

“…Similar to the laser sintering patterning, selective intense pulsed light (IPL) sintering patterning has also been widely explored to obtain desired MNW patterns. An IPL-irradiated area cannot be easily removed due to the strong adhesion due to a fusion between the underlying polymer substrate and the NWs, as MNWs are instantly embedded into the substrate at the nanometer level. − The non-irradiated NWs were easily delaminated from the substrate through wiping or sonicating in a proper solvent, enabling one to pattern the MNW-based TCFs. − For example, a CuNW film covered with a mask was irradiated by IPL. After irradiation, the non-irradiated NWs were selectively wiped away by a fabric soaked with isopropyl alcohol, which was used as the main solvent for the CuNW ink.…”

With the advance in flexible and stretchable electronics, one-dimensional nanomaterials such as metal nanowires have drawn much attention in the past 10 years or so. Metal nanowires, especially silver nanowires, have been recognized as promising candidate materials for flexible and stretchable electronics. Owing to their high electrical conductivity and high aspect ratio, metal nanowires can form electrical percolation networks, maintaining high electrical conductivity under deformation (e.g., bending and stretching). Apart from coating metal nanowires for making large-area transparent conductive films, many applications require patterned metal nanowires as electrodes and interconnects. Precise patterning of metal nanowire networks is crucial to achieve high device performances. Therefore, a high-resolution, designable, and scalable patterning of metal nanowire networks is important but remains a critical challenge for fabricating high-performance electronic devices. This review summarizes recent advances in patterning of metal nanowire networks, using subtractive methods, additive methods of nanowire dispersions, and printing methods. Representative device applications of the patterned metal nanowire networks are presented. Finally, challenges and important directions in the area of the patterning of metal nanowire networks for device applications are discussed.

“…Many as-prepared nanowire FEs that only relies on Van der Waals force to contact each other suffer from poor conductivity because of the weak contact at the junctions. To enhance the stability and conductivity of AgNWs FEs, a series of work have been developed to improve the wire-wire contact, ,− including thermal welding, mechanical pressing, plasmonic welding, cold welding, and electrochemical coating. However, those mentioned methods often have many shortcomings.…”

Ionic flexible sensors (IFS) usually consist of an ionomer matrix and two conductive electrodes, the failure of which mostly originates from interfacial debonding between matrix and electrode layers. To improve electrode's adhesion and impedance matching with matrix, polymer binder or plasmonic heating technology is used to enhance the adhesion of electrodes, but there are technical challenges such as high resistance and harsh conditions. Herein, inspired by biological hair, we proposed a reliable and facile method to form AgNWs@Au-embedded Nafion flexible electrodes (AN FEs) for IFS without rigorous temperature and harsh conditions. Through integrating the spraying and electrodepositing Au method, we achieved that the AgNWs are partly embedded in the matrix layer for forming the embedded layer, similar to the root of biological hair, which is used to fix the FEs and collect the ion charges. The other parts of AgNWs exposed on the surface form the conductive mesh layer for transmitting the signal, analogous to the tip of biological hair. Compared with other AgNWs FEs, AN FEs exhibit high adhesion (∼358 kPa) and low sheet resistance (∼ 3.7 Ω/□), and high stabilities after 100 washing cycles, 200 s H 2 O 2 corrosion or 1500s HCl corrosion. A self-powered IFS prepared by AN FEs can achieve dual sensing of mechanical strain and ambient humidity and still has promising sensing performance after being exposed to air for 2 months, which further indicates potential applications of the prepared FEs in next-generation multifunctional flexible electronic devices.
