Apple is assembling a team of experts in sensors that monitor the human body, according to a report by 9to5Mac, with expectations growing that the Cupertino giant will shortly launch a fitness-orientated wearable computer, perhaps in the shape of an iWatch.

According to the report, Apple has been recruiting from companies such as AccuVein, C8 MediSensors and Senseonics.

The new recruits named so far are Ueyn Block, who left C8 MediSensors in January, and was hired by Apple in March as technical lead for optical sensing. Todd Whitehurst, in charge of a team that developed an “implantable continuous glucose monitor” at Senseonics, was hired recently by Apple as a director of hardware development.

GigaOm reports that C8 MediSensors went out of business, but Apple hired several of its former employees, according to the company’s former CEO.
