Resumen
Theprinted electronics presents the outstanding proposal to produce low-cost, solution-processable, vacuum-free and flexible devices. In this context, many researchers have been made efforts to obtain printed memories that works with low voltage bias, high on/off ratio and storage stability. Here, we report a novel low-cost printed version of a memristor based on spray coated films of indigo and colloidal graphite. This memory showed high performance for printed memristors, being the most remarkable aspect of this device its high on/off ratio of 1.6 × 106 at -1.15 V, and 3.1 × 104 for voltages as low as +0.1 V. The pulse-test mode read at +0.1 V revealed very stable endurance characteristics even after 100 readings and retention time over 104 s, as desired by the printed electronics niches.
