Intel announced a line of tiny chips for new markets, including wearable devices. Called Quark, it is Intel’s bid to stay relevant in the era of wearable computing. It’s approximately one-fifth the size of the company’s already-small Atom chip and draws one-tenth the power. Intel will sample circuit board designs based on the first product in this family during the fourth quarter of this year. Initially, it will be aimed at the industrial, energy, and transportation markets.
