Xconomy Voices brings you conversations with the world’s leading entrepreneurs and innovators. Our very first guest is Mary Lou Jepsen, founder and CEO of San Francisco-based Openwater. Jepsen is putting her expertise in display manufacturing to work to build inexpensive, wearable sensor systems that use infrared light from LCDs to collect data from inside the human body. Such technology could make lifesaving medical-imaging data much more accessible, and maybe even give us “telepathy”—or at least, the ability to see what people are thinking about by looking inside their brains.
