Free space wireless charging for electronic paper display tags
Energous in California has signed a deal with E Ink Holdings to develop Electronic Paper Display (EPD) tags for IoT displays such as logistics tags, electronic shelf labels and retail signage using its WattUp technology for wireless charging at distances of up to 5m.
“Our partnership with E Ink opens up an entirely new application for our revolutionary WattUp wireless charging technology,” said Stephen Rizzone, president and CEO of Energous. “We believe that WattUp is a very attractive option for companies within the electronic ink industry because of the significant advantages it offers, such as a small footprint, interoperability and freedom of placement, while providing over-the-air charging capabilities,”
The global e-paper display market was estimated to grow to $5.73bn by 2023, according to Market Research Future. Competitors Ossia and Powercast have both launched wireless charging systems for supermarket shelves, with Ossia signing a similar deal with E Ink last year.
Energous has a strategic deal with London-based Dialog Semiconductor for the silicon that enables the WattUp wireless charging. The goal of the collaboration is to enable manufacturers to use E Ink’s Display technology and layer in Energous’ WattUp wireless charging technology before printing the ink onto an EPD tag.
Using the WattUp PowerHub transmitter, the EPD tags can potentially be charged wirelessly at distances up to 5m away. “EPD’s low-power consumption is one critical factor that serves the industry needs in IoT,” said Johnson Lee, CEO of E Ink. “We believe the wireless charging technology offers the versatility and flexibility that will enable greater freedom for users of our EPD tags,”
“We believe the announcement of this partnership highlights one of the biggest potential applications of Energous’ WattUp RF-charging,” said Mark Tyndall, senior vice president corporate development and strategy at Dialog Semiconductor. “Flexible charging options will help enable a fully connected ecosystem for both electronic signage and asset tags.”
