The commercial space business has blossomed over the past decade. Two companies, though, have grabbed the spotlight, emerging as the most ambitious of them all: Blue Origin and SpaceX.

At first glance, these two companies look a lot alike. They are both led by billionaires who became wealthy from the Internet: Jeff Bezos of Blue Origin earned his fortune from Amazon.com, and Elon Musk of SpaceX got rich initially from Web-based businesses, notably PayPal. Both companies are developing large, reusable launch vehicles capable of carrying people and satellites for government and commercial customers. And both are motivated by almost messianic visions of humanity's future beyond Earth. This coming year, we'll likely see some major milestones as these two titans continue to jockey for position.

Graphene Tattoos Measure Blood Pressure Continually

Ultra-lightweight sensors could work for days

Graphene tattoos placed over the two major arteries in the wrist monitor blood pressure non-stop by measuring impedance of electrical current through tissue.

Blood pressure measurement hasn’t changed much since the invention of the inflatable cuff-based sphygmomanometer in 1881. People can use the device to give readings a few times a day, but that’s not enough to give a holistic view of cardiovascular health.

New electronic tattoos made of graphene continuously read blood pressure for days. The ultra-thin, light sensors could allow monitoring of a patient’s blood pressure while they go about their daily activities.

Mojo Vision Puts Its AR Contact Lens Into Its CEO’s Eyes (Literally)

With batteries on board and communicating wirelessly, the augmented reality contact lens reaches a major milestone

Editor’s note: In March, I looked through Mojo Vision’s AR contact lens—but I didn’t put it in my eye. At that point, while non-working prototypes had been tested for wearability, nobody had worn the fully functional, battery-powered, wirelessly communicating, device. Today, Mojo announced that its augmented reality lens had gone on-eye—specifically, on the eye of Mojo Vision CEO Drew Perkins, on 23 June.

“I’ve worn it. It works....and it was the first ever on eye demonstration of a feature complete augmented reality smart contact lens,” reported Perkins in a blog post. “The final technical hurdle to wearing the lens was ensuring that the power and radio communications systems worked without wires. Cutting the cord [proved] that the lens and all major components are fully functional and reduce many of the technical challenges in building a smart contact lens.”
