Performance of inkjet-printed strain sensor based on graphene/silver nanoparticles hybrid conductive inks on polyvinyl alcohol substrate

Printed flexible mechanical sensors

“…2.1.3 Graphene-based. All graphene-based flexible strain sensors identified in the literature have a relatively large sensing range, 124,[136][137][138] as shown in Fig. 2.…”

“…Htwe et al 's strain sensor was made by inkjet printing graphene/AgNP ink onto a polyvinyl alcohol (PVA) substrate. 138 Inks with different concentrations of graphene ranging from 0.1 wt% to 0.7 wt% were prepared to investigate their effects on properties, including electrical conductivity. It was found that the conductivity of the ink increased with the increasing concentration of graphene, until reaching the percolation threshold of 0.5 wt%.…”

Hybrid nanomaterial inks for printed resistive temperature sensors with tunable properties to maximize sensitivity

“…18 Others have utilized silver nanoparticle–graphene hybrid ink to increase strain sensitivity, resulting in a high gauge-factor strain sensor. 19 These diametrically opposed applications demonstrate that through appropriate material selection, silver-nanoparticle hybrid inks can be designed and tuned to enhance a specific application.…”

Preparation of paper-based conductive pattern for 3D printing

“…According to the actual needs of the product, a relatively suitable conductive ink was chosen. Graphene inks in the electronics industry were mainly used by gravure printing [7], screen printing [8], inkjet printing [9,10], 3D printing [11] and so on. In gravure printing and screen printing the manufacturing process required many processes from early drawing, photo plate making, film formation to final cleaning and inspection.…”
