Star Trek gets closer to becoming home tech

Winners of an invention contest built handheld medical devices inspired by science fiction.

By STEPHEN ORNES  ||  MAY 2, 2017

A half-century ago, the television series Star Trek introduced the world to the idea of a handheld device called a tricorder. It had a range of functions, including medical ones. For example, it easily diagnosed injuries and disease in the Starfleet crew. Now, aspects of this science fiction invention are becoming reality. A device called DxtER has just won a multi-million-dollar competition. One day soon, the winners hope, such a tricorder-like device might become part of regular home health care — much like a medical thermometer is today.



Paoli-Based Startup, Basil Leaf Technologies takes top prize in the Qualcomm Tricorder XPRIZE

Paoli, Pa. (April 12, 2017) – Basil Leaf Technologies has been announced as the top winner of the Qualcomm Tricorder XPRIZE, a 5-year global competition sponsored by the Qualcomm Foundation for teams to develop a consumer-focused, mobile device capable of diagnosing 13 medical conditions and continuously capturing five vital health metrics—all within a well-designed consumer experience. A total of 312 teams around the world entered the competition at the outset. Basil Leaf Technologies entered the competition under the team name “Final Frontier Medical Devices.”

Basil Leaf Technologies’ prototype is DxtER (pronounced Dexter), a portable device capable of collecting and interpreting large amounts of data to accurately diagnose specific medical conditions, provide users with real-time insight regarding their health, and guide them to appropriate action. Our device gives users access to continuous, reliable health data - the information patients and providers need to more effectively manage chronic health conditions, such as diabetes and congestive heart failure.

Drawing on years of experience as an Emergency Department physician, Basil Leaf Technologies founder, Dr. Basil Harris, understands that patients want to be meaningfully engaged in their own health decisions.

“Our company is at the forefront of a new era of consumer medical technology,” said Harris. “An entirely new market is emerging that engages consumers and puts them in the driver’s seat. Our device is smart and simple, giving people the help and answers they need when they need this input the most. There is nothing like it in existence, and we believe this technology will change the face of health care.”

Basil Leaf Technologies believes in the power of technology to improve people’s health. Their Qualcomm Tricorder XPRIZE team includes physicians, engineers, designers, health policy experts, mobile technology and sensor professionals who are passionate about revolutionizing healthcare.
