Researchers at the University of Groningen have developed a technology for a plastic ferroelectric diode that could achieve a breakthrough in the development of ultra-low-cost plastic memory material.

The technology is similar to that used in Flash memory chips. The memory diode can be programmed quickly, retains data for a long time, and operates at room temperature. The voltages needed for programming are low enough for the diode to be used in commercial applications and the material can be manufactured at low cost using large-scale industrial production techniques.

Applications include an electronic price tag that could be read at the cash register of retail stores, replacing bar codes; and in a packaging material that could warn consumers when a product is nearing its expiration date.
