Apple has achieved much in their development of the world's best smartphones, computers, laptops, and tablets. Based on their recent flurry of acquisitions and a meeting with Tesla CEO Elon Musk, the company appears in search of new fields to define, according to SF Gate.

Even more intriguing is their interest in the medical field, specifically a device that anticipates heart attacks based on tracking the sound blood makes as it travels through arteries.

Because such a device would require constant contact with one's body anyway, it could be a feature in the rumored iWatch, according to SF Gate. With many of its competitors already in the smart watch market, projected to increase substantially in the years to come, it only makes sense for Apple to enter a version of its own.

Perhaps they're simply waiting for the right moment. Rather than develop an impressive but limited device like those that have been made from Sony and Samsung, among others, Apple may prefer to launch a smart watch when they can incorporate more advanced technologies, such as the heart attack feature.

According to Bill Kreher, an analyst with Edward Jones Investments in St. Louis, the move towards a smart watch and meetings with fellow tech giants like Elon Musk and Tesla represent a necessary move if Apple is to retain its reputation for the cutting edge, SF Gate reported.

"Apple must increasingly rely on new products to reignite growth beyond the vision" (of the late Steve Jobs). They need the next big thing."

Of the meeting with Musk, which could amount to anything from a partnership to a possible acquisition by Apple to strictly a meeting, German investment banking analyst Adnaan Ahmad said an acquisition in particular would dramatically change Apple's "growth profile."

"I know this is radical and potentially 'transformative' but this would radically alter Apple's growth profile," Ahmad wrote. "In Elon Musk, you could strike up a partnership and obtain a new iconic partner to lead Apple's innovation drive."

For Tesla, the merge or whatever it becomes would most likely benefit them for the financial backing, SF Gate reported.
