According to a news article on MacRumors.com, Apple Inc has hired a former Masimo Corp officer, a hire that the website speculates could be related to Apple’s rumored “smart-watch” project, the iWatch.

“Michael O’Reilly, MD, formerly the Chief Medical Officer and EVP of Medical Affairs at Masimo Corporation, left his position in July of 2013 to take on a role at Apple, possibly on the iWatch team,” the MacRumors article reports.

From the article:

Reports have suggested that Apple’s smart watch project, the iWatch, could focus heavily on health sensors and biometrics, possibly including features like a pedometer and a heart rate monitor. Apple’s multitude of hires in the health field does suggest, however, that the company could include even more advanced sensor technology in the iWatch or in a future product.

With the addition of O’Reilly, Apple has now hired employees with expertise in pulse oximetry, vasculature visualization (vein finding), non-invasive glucose monitoring, blood chemistry monitoring via microneedle, heart/breath rate monitoring, and fitness. Notably, several hires have also had experience with low-profile, non-invasive biosensor devices.
