Packing four sensors into a housing smaller than an iPod Nano, the CORE 2 will be the smallest wearable multi-sensor device of its kind as well as the first to offer a choice of interchangeable jewelry- like faceplates, straps and cuffs for a fashion look.
The device, which is about the size of an Apple iPod Nano or a square-shaped matchbox, can be attached to a strap and worn on the wrist or the upper arm.
