Actress Lindsay Lohan is voluntarily wearing an anklet that can detect alcohol consumption via sweat. The Washington Post says that the device called the Secure Continuous Remote Alcohol Monitor, or SCRAM, a sweat-sensing, electronically monitored anklet, has rocketed in popularity. Since its launch in 2003, the ankle bracelets have helped keep 40,000 drinkers on the wagon, says the manufacturer, often as a condition of parole or probation for alcohol offenders. Alcohol Monitoring Systems, a Colorado-based company, manufactures the anklets.
The anklet is typically court-ordered, as is the more familiar the house arrest bracelet. The SCRAM ankle bracelets, which cannot be removed by the wearer, reads the ethanol content of ankle sweat every hour. Once a day, the anklet wearer must be near the SCRAM modem, which reports the data to SCRAMNet, where law enforcement can easily see if court-ordered teetotalers are behaving.
