Ankle Bracelet Measures Blood-Alcohol Level
Law-enforcement agencies in 20 states have begun using a special
ankle bracelet to prevent DWI offenders from drinking and driving,
News 14 Carolina in Charlotte, N.C., reported Aug. 26.
The new technology in the ankle bracelets automatically tests the
wearer's sweat every hour for traces of alcohol. Probation officers
monitor the readings.
"This is the first offender or patient bracelet that tests
offenders consistently," said Don White of Alcohol Monitoring
Systems. "We're able to test the molecules of ethanol that
are coming off the ankle because 5 percent of everything you drink
comes out your body."
Currently, 200 law-enforcement agencies are using the new technology.
So far, the bracelet has held up in legal challenges.
