Samsung shows off foldable phone that changes color

Phone would support wearable RFID health monitoring devices, Samsung says

Samsung this week revealed a concept smartphone that can fold out into an almost tablet-sized device, and uses a new reflective display that changes color like a chameleon.

Online publication All Things D reported that Samsung strategy chief Young Sohn Tuesday demonstrated the concept smartphone at the start of the MobileBeat conference in San Francisco.

The phone has two side flaps that fold out to expand the phone's operable size.

The concept phone's reflective display can change its RGB color through the use of embedded photonic crystals. The color of the display represents different modes the phone can be in.

In a video shown at the MobileBeat conference, a disposable RFID chip in the form of a wearable patch is shown sending the vital health signs of a user to the new phone. The data can be forwarded to a physician.

The video states that an "electromagnetic wave generator and detector are integrated in the patch sensor."

Sohn said while only a small number of RFID wearable sensors are in use today, that number will skyrocket as the chips become part of clothing, glasses and other objects.
