Flexible Organic Flash Memory

Advances in organic electronics have enabled the fabrication of a number of core devices on flexible plastic substrates. These include transistors, light-emitting diodes, actuators, and sensors. Sekitani et al. (p. 1516) use a low-temperature hybrid dielectric based on a thin metal oxide and a self-assembled monolayer to develop flexible floating-gate memory transistors with small program and erase voltages. These are integrated into a flexible large-area sensor area, capable of storing values from applied external pressures.
