US chipmaker Intel has stepped up its investment in wearable technology with the acquisition of Basis Science, a firm known for its health tracking services and devices.

The start-up from San Francisco will be merged with Intel's New Devices Group, which focuses on wearable computing and connected devices.

Intel did not disclose the value of the deal.

But according to industry analysts the acquisition was worth $100m (£60m).

Basis Science is known for its health-tracking device, the Basis band, which monitors the user's heart rate and calorie-burning, among other things.

The Basis band will continue to be sold and supported through its existing channels.
