NEW YORK (AP) — Chipmaker Intel has bought Basis Science, the startup behind the popular fitness tracker by the same name, for an undisclosed sum.

The deal, announced Tuesday by Santa Clara, Calif.-based Intel Corp., comes as the still-nascent market for wearable gadgets is heating up. So far, a lot of these gadgets are fitness and wellness trackers. This includes the Basis band, which tracks users’ activity level, heart rate, sleep patterns and other data.
