Vessyl Automatically Knows What You're Drinking in Real-Time

"Consumption is as important or more important as what we track through exercise," says Lee, "so we developed a sensor that could instantly analyze the nutritional content of what’s inside a beverage … on a molecular level." Lee won’t say exactly how the sensor works. He likens it to the kind of sensor you’d find in a bottling factory that analyzes batches of liquid (or other foods) to make sure each batch is consistent. "It’s the kind of sensor you’d use for quality control," Lee says, "and the sensor doesn’t degrade. It’s non-contact."
