Lohan is now donning an alcohol-monitoring ankle bracelet along with her usual designer duds, her publicist Leslie Sloane Zelnick told ABC News.Wow, an alcohol sensing bracelet, cool. I wonder how it works?
The bracelet, which will track and record even the slightest trace of alcohol Lohan consumes, is being worn voluntarily by the star in an effort to prove she's serious about staying sober.
The 8-ounce bracelet tracks the user's alcohol level through a process called "transdermal alcohol testing," which essentially takes samples from the hard-to-see layer of sweat that is on everyone's skin.More info here. Neat idea, but a little bit large. Make it a little smaller and I think they have something here.
For a home installation fee of just $60, the device records the level of alcohol either every 30 minutes or every hour, depending on the offender's probation guidelines, explained Brown.
The offender must be within 30 feet of a wireless modem once a day, allowing the collected data to be transmitted onto a secure Web site where probation officers can be alerted of any alcohol consumption.
Tampering with the device is nearly impossible, thanks to an infrared laser beam that measures the distance between the person's leg and the bracelet. If an offender tries to slip something in between the bracelet and their skin, the distance the beam travels changes and a tampering alarm is recorded and reported to authorities.
