Abstract: System, method and application that obtains, consolidates, and integrates multiple sources of data including Transdermal Alcohol Concentration (TAC) along with drinking diary, photo/video, breath analyzer, other biological data (e.g., heart rate, skin conductance. blood flow, person-level biometrics), and environmental data (e.g., ambient temperature, humidity, GPS) and uses models described herein to convert TAC obtained from a wearable biosensor into estimated Blood Alcohol Concentration (BAC) or Breath Alcohol Concentration (BrAC).
