Abstract
A wearable device may be provided for detecting cumulative alcohol consumption. Such a wearable device may include an adhesive layer that adheres to skin and that allows sweat from the skin to pass through and a customizable ink layer that reacts irreversibly to change color along a gradient as ethanol is detected in the sweat. The customizable ink continues to increase color intensity along the gradient as ethanol continues to be detected in the sweat over time.
