“…Shown in figure 3F is a reasonable, but not exhaustive, attempt to summarise data from the literature by plotting the maximum conductivity achieved versus the maximum annealing temperature used. We have limited data to inkjet-printed structures and categorised in terms of the materials used: Graphene, [16][17][18][19][20][21][22][23][24][25][26] nanotubes 13, 40 and nanoparticles of silver 10,[41][42][43][44] and gold. 45 We find the majority of inks to demonstrate lower conductivity and/or higher processing temperatures than those reported here.…”

The development of printed electronics will require the ability to deposit a wide range of nanomaterials using printing techniques. Here we demonstrate the controlled deposition of networks of silver nanowires in well-defined patterns by inkjet printing from an optimized isopropyl alcohol-diethylene glycol dispersion. We find that great care must be taken while producing the ink and during solvent evaporation. The resultant networks have good electrical properties, displaying sheet resistances as low as 8 Ω/□ and conductivities as high as 10(5) S/m. Such optimized performances were achieved for line widths of 1-10 mm and network thicknesses of 0.5-2 μm deposited from ∼10-20 passes while using processing temperatures of no more than 110 °C. Thin networks are semitransparent with dc to optical conductivity ratios of ∼40.

“…The sintered silver ink might have a hairy fuzzy appearance if the silver content is low; however, this can be overcome by raising the sintering temperature to 250°C [25]. Plasma and laser energy is another approach that can also be used in the sintering process of silver inks [26][27][28][29]. Another sintering method called solution soaking treatment can be applied to sinter silver particles on paper or plastic substrates [30].…”

This paper presents the performance of a new nonwoven piezo-resistive sensor for capturing cardiorespiratory signals. The novel piezo-resistive sensor is fabricated by sandwiching a nano silver electro-conductive ink impregnated nonwoven material between two layers of knitted silver fabric that function as sensor electrodes. The paper describes the technology for minimizing the signal noise due to motion artifacts in the sensor. The nonwoven piezo-resistive sensor is tested on volunteers by capturing their cardiorespiratory signals, where the signal noise is filtered using a bandpass filter. The paper further presents the analysis of the performance of the sensor together with a comparison against a commercially available, portable, cardiorespiratory signal monitoring device. The study shows that the wearable nonwoven piezo-resistive sensor system is highly sensitive, and it is an accurate and reliable sensor for capturing cardiorespiratory signals.

We developed an ultra-high speed photonic sintering method involving flash white light (FWL) combined with near infrared (NIR) and deep UV light irradiation to produce highly conductive copper nano-ink film. Flash white light irradiation energy and the power of NIR/deep UV were optimized to obtain high conductivity Cu films. Several microscopic and spectroscopic characterization techniques such as scanning electron microscopy (SEM), a x-ray diffraction (XRD), and Fourier-transform infrared (FT-IR) spectroscopy were employed to characterize the Cu nano-films. Optimally sintered Cu nano-ink films produced using a deep UV-assisted flash white light sintering technique had the lowest resistivity (7.62 μΩ·cm), which was only 4.5-fold higher than that of bulk Cu film (1.68 μΩ•cm).
