“…The achieved value of ρ is about 1.1 times higher than the resistivity of bulk platinum 1.06·10 −7 Ω∙m. In comparison with other studies [ 73 , 74 , 75 , 76 ], the developed platinum nano-ink shows lower values of resistivity after thermal sintering, see Table 3 .…”

“…Indeed, the inset to Figure 11 shows that the Pt lines sintered at 750–900 °C have a high degree of sintering and low residual porosity. Additionally, it can be seen from comparative Table 3 that the developed nano-ink has a high concentration of particles (25 wt.%) in comparison with other studies [ 73 , 74 , 75 , 76 ], see Table 3 . The use of concentrated nano-ink is an additional advantage since it allows reducing the time for printing lines with a given resistance.…”

A cost-effective, scalable and versatile method of preparing nano-ink without hazardous chemical precursors is a prerequisite for widespread adoption of printed electronics. Precursor-free synthesis by spark discharge is promising for this purpose. The synthesis of platinum nanoparticles (PtNPs) using a spark discharge under Ar, N2, and air has been investigated to prepare highly conductive nano-ink. The size, chemical composition, and mass production rate of PtNPs significantly depended on the carrier gas. Pure metallic PtNPs with sizes of 5.5 ± 1.8 and 7.1 ± 2.4 nm were formed under Ar and N2, respectively. PtNPs with sizes of 18.2 ± 9.0 nm produced using air consisted of amorphous oxide PtO and metallic Pt. The mass production rates of PtNPs were 53 ± 6, 366 ± 59, and 490 ± 36 mg/h using a spark discharge under Ar, N2, and air, respectively. It was found that the energy dissipated in the spark gap is not a significant parameter that determines the mass production rate. Stable Pt nano-ink (25 wt.%) was prepared only on the basis of PtNPs synthesized under air. Narrow (about 30 μm) and conductive Pt lines were formed by the aerosol jet printing with prepared nano-ink. The resistivity of the Pt lines sintered at 750 °C was (1.2 ± 0.1)·10−7 Ω·m, which is about 1.1 times higher than that of bulk Pt.

Organic electrochemical transistors (OECTs) have drawn significant interest because of their low cost, biocompatibility, and ease of fabrication, allowing them to be utilized in various applications including flexible displays, electrochemical sensing, and biosensing. Key components of OECTs are the gate, source, and drain electrodes. Herein, OECTs with laser‐induced graphene (LIG) electrodes are demonstrated. The electrode patterns for the source, drain, and gate are created by converting the polymer substrate polyimide (PI) into LIG using a scanned laser. The process is simple and inexpensive without complicated chemical synthesis routines or expensive materials such as gold. Patterns can be customized quickly and digitally. The low‐cost and porous LIG electrodes with low contact resistance and good electrical stability play an essential role in device performance. The minimum sheet resistance achieved with this laser method for the square patterned electrodes is 7.86 Ω sq−1. The LIG‐based OECTs demonstrate good electrical modulation with ON–OFF ratio of 72.80 and high ON current on the order of mA. The LIG‐based OECTs exhibit comparable or better performance in comparison with other reports of OECTs on plastic substrates using more complex fabrication methods in terms of OFF current, ON current, transconductance (gm), and contact resistance.
