The first company from IV is called QSense. It’s developing a fleet of small sensors that push beyond the capabilities of quantified-self products such as the Fitbit. One sensor, called LucidAir, is a small doughnut-shaped metallic disk that can measure air quality and then send the data to a smartphone app. The technology allows people to upload the information publicly, creating a database of cities with good and bad air. Rosenberg expects the product to sell well in Asia, where air quality has become a huge concern. A second product is LiquidIO. People touch this small device with their finger, and it reports their hydration levels.
