“…[7,8,9] Nature is nothing but an extremely efficient energy consumption engine that we could rely on for infinite inspiration. [10,11,12] The diversity of natural materials offers a plethora of unexplored phenomena to researchers, and starts already to open new fields in physics and chemistry as well as materials engineering. [13,14,15,16] An exciting area of cross-disciplinary engineering currently emerging is the implementation of natural or nature-inspired, "green" materials for various electronic devices interfaced with living matter.…”

Natural dielectrics are emerging nowadays as a niche selection of materials for applications targeting biocompatibility and biodegradability for electronics and sensors within the overall effort of scientific community to achieve sustainable development and to build environmental consciousness. The two natural resins analyzed in this study, silver fir and Rocky mountain fir demonstrate robust dielectric properties and excellent film forming capabilities, while being trap free dielectrics in high‐performance organic field effect transistors (OFETs) operating at voltages as low as 1 V. Immense research possibilities are demonstrated through the avenue of inorganic nanofillers insertions in the natural resins film, that opens the door for fabrication of very low voltage OFETs with high dielectric constant insulating layers.

“…The substrate exerts influence on the electrical conductivity of the coating under different ambient conditions [78][79][80][81]. In this backdrop, the reasoning behind the order of electrical resistivities mentioned in section 3.4.3 was scrutinised in the literature, and two properties were discerned to play an important role: porosity of the substrate [82,83] and elasticity of the coating-substrate interface [84,85].…”

Graphene is gaining significance in applications such as sensors, antennas, photonics and spintronics. In particular, it is suitable for printing components and circuits affording the properties of high conductivity alongside flexibility, elasticity and wearability. For this application, graphene is typically customised into a fluidic form—ink or paint. This paper reports a novel, economical, scalable methodology for synthesising electrically conductive graphene-based coagulated composite that could be utilised in the above-mentioned applications. Composites are prepared from graphene powder/ink and screen-printing ink (GP–SPI and GI–SPI, respectively) at different mass ratios, and the optimal composition is identified by brush coating on paper in the form of rectangular strips. As a proof of concept, at optimum mass ratios, the GP–SPI and GI–SPI composites exhibit electrical conductivities ranging 0.068–0.702 mS m−1 and 0.0303–0.1746 µS m−1, in order. The as-prepared conductive composites are then screen-printed onto a square with an area of 1 cm2 on ceramic, FR4, glass, paper, polyester and wood substrates. The coagulated GP–SPI and GI–SPI composites are compatible with all these substrates and yield a conductive coating, demonstrating their suitability in multifaceted applications. Furthermore, the method proposed herein eliminates the need for rare/precious expensive materials, state-of-the art equipment, highly skilled personnel and costs associated with the same, thereby broadening the avenues for low-cost, fluidic graphene-based functional composites.

“…[4][5][6] Carbon based organic electronics in contrast to traditional electronics enable the fabrication of extremely flexible, highly conformable and even imperceptible electronic devices. 7 Such properties stimulate ground-breaking applications that may lead to new mainstream solutions in information and communication technology such as ambient intelligence for daily-life assistance, 8,9 soft robotics and actuators, 10 conformable and self-sustaining bioelectronic components for sports and recreation, [11][12][13] as well as imperceptible electronic platforms for surgical and diagnostic implants. [14][15][16][17][18][19][20][21][22] Materials that are easy to synthesize in high yield at low cost 23 and that have widespread application as textile or cosmetic colors are very appealing for the development of sustainable organic electronic devices and integrated sensors.…”
