University of Tokyo researchers have used organic materials to create organic flash memory. Physically flexible, the nonvolatile memory has the same basic structure as flash memory. Organic flash memory has the potential to be used for large-area sensors, electronic paper, and other large-area electronic devices. However, organic flash memory’s retention time is currently limited to 24 hours. Nonetheless, the development could lead to more physically versatile computing devices. For example, wearable storage that conforms to a body shape for video capture is a possibility, as is the use of rounded objects as storage devices. There could be practical as well as nefarious uses for non-linear, flexible technologies, from monitoring tire pressure to capturing data from someone’s shoes to determine where they have been. The technology is unlikely to be ready for everyday use for a number of years.
