Polymer and nanoparticle-composite bistable devices, which fall under the category of Organic Bistable Devices (OBDs), provide non-volatile, two-state ON/OFF behavior for potential memristor or other applications. These materials consist of insulating, semiconducting, or conducting polymers such as poly(methylmethacrylate) (PMMA), poly(vinylcarbazole) (PVK), or poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS), respectively. Composites can be made by blending these with inorganic nanoparticles made from materials such as silver, gold, or zinc oxide. Such devices offer several potential advantages compared with their inorganic counterparts. These include reduced cost from solution-based methods of deposition, ease of direct-write printing over large areas, high throughput processing, and light-weight and flexible mechanical properties. Here we review the materials, designs, physics, and operation of these devices. We conclude the chapter with a discussion of possible applications, including recent advances in neuromorphic engineering specifically geared toward use in robotics.
