(11 September 2018) E Ink is in the midst of developing next generation e-paper products that do not need a battery. The company has just partnered with Fujitsu to design a reference design board for battery-less products such as badges, price tags, luggage tags and eventually e-readers. The byproduct of this new partnership will likely bear fruit sometime in late 2019 or 2020.
Fujitsu is not starting from scratch when developing this new board, they do have a reference design called FRAM and they appear to be using UHF FRAM RFID LSI. Fujitsu has also been in the e-reader business a very long time, so this is nothing new do them. They developed prototype color epaper back in 2010 and they have been providing with connectors on the boards for popular e-readers for years.
