Design of versatile printed organic resistor based on resistivity (ρ) control

Ultra-low power non-volatile resistive crossbar memory based on pull up resistors

“…The surface tension of the ink was found to be 20e24 mN/m. Ink for resistors is prepared as: mixing MEH:PPV and PMMA in acetonitrile as reported in our previous work [22]. Ink for silver electrodes is prepared as: Ag nano particle paste sigma Aldrich 55%wt is diluted in 10 ml ethylene glycol solvent mixed for 1 h on magnetic stirrer and then 20 min bath sonication.…”

“…A PVP is one of the most commonly used polymers in insulators and in thin film memory applications [22,23]. Active layer of the memristors were prepared as: the PVP of 0.40 g was dispersed in NMP (4 ml) solvent by bath sonication for 30 min at room temperature followed by centrifugation at 3000 rpm for 20 min.…”

“…The pull-up resistors are located at the ends of column bars on the terminal pads. Resistive material is deposited in between two silver dots (terminal pads) and the resistance is precisely controlled through the resistivity method [22].…”

All-printed and highly stable organic resistive switching device based on graphene quantum dots and polyvinylpyrrolidone composite

“…Among these processes, electro-hydrodynamic (EHD) method is the best candidate for nano-meter film deposition of continuous drop and atomization types [35]. EHD method is a cost effective, ambient temperature deposition, feasible for prototyping and mass production of printed electronic devices, free of harmful radiation, and rapid fabrication deposition technique [36]. EHD is deployed in the current work to electro-hydrodynamically atomize the G-QDs/PVP composite film and for the silver micro patterned electrodes.…”

Stretchable photo sensor using perylene/graphene composite on ridged polydimethylsiloxane substrate

“…This kind of system needs integration of components such as sensors, memory, battery, display unit, and actuators onto elastic polymeric substrate [2]. Many researchers have studied various stretchable core electronic devices, such as transistors [6], resistor [7] light-emitting diodes [8], sensors [9], solar cells [10], and batteries [11]. Sensors are the key components to acquire data from the environment for the further process and actions.…”
