Smart badge reference design offers multiyear battery life
Electronic paper (ePaper) technology company E Ink Holdings and ultra-low-power Bluetooth wireless solutions provider Atmosic have together announced a reference design for eBadge applications.

Through the joint project, Atmosic will offer a power-optimized eBadge reference design, featuring one of E Ink's 2.9” or 3.7” black and white displays, or 4.1” Gallery Palette color displays. The kit utilizes Atmosic's M series extreme low-power Bluetooth LE platform, enabling long, multiyear battery life, which can be extended by using optional on-chip energy harvesting.

The reference design addresses the smart badge market, which is set for significant growth over the next few years, according to reports. The growth of smart badges can be attributed to the convenience and transaction security they provide, as well as their capability for tamper-proof storage of information and account identity of users.

"This innovative reference design combines E Ink’s low-power electronic ink technology with the industry’s absolute lowest power Bluetooth LE platform, the M series from Atmosic, to enable the rapidly growing eBadge market segment," says Thomas Lee, Executive Director of Sales at Atmosic. "With such a low-power budget, developers can add a host of features to build a secure, cost-efficient eBadge solution that can run on the same battery for multiple years or even have unlimited battery life with energy harvesting."

Timothy O’Malley, AVP of the US Regional Business Unit, E Ink says, "With the increased popularity of connected devices featuring displays, the need for enhanced functionality while balancing battery life is a key concern for many product designers. The combination of E Ink's low-power display and Atmosic's low-power Bluetooth solutions gives product designers a solution that enables visual data without the need for bulky batteries or device charging challenges."

The kit can be used in landscape or portrait mode, and under a typical eBadge use case of three (3) image changes per day, a small CR2032 coin cell battery will last over three (3) years, say the companies. This low-power eBadge can also provide visual updates including a photo, location information, alert messages, and text messages. The use of energy harvesting
