Researchers concluded such devices could prevent 85 percent of drunk driving- related deaths in the U.S. over a span of 15 years. Car breathalyzers can measure a driver’s blood alcohol content from their breath or through the fingertips. Alcohol ignition interlocks include devices that drivers can exhale into, as well as those they can place their fingers on. When a person consumes alcoholic drinks, alcohol is quickly absorbed into the bloodstream, but its chemical structure remains intact and therefore easily detectible. Once the device absorbs the alcohol, ethanol in the alcohol is oxidized in the device’s fuel cells. This produces acetic acid, protons and free electrons. When electrons are transferred through a wire to the other side of the fuel cell, they produce an electrical current that can be measured by the breathalyzer. The breathalyzer calculates the equivalent blood alcohol concentration based on the amount of electrical current it detects. A blood alcohol concentration of 0.08 percent is the legal limit in all fifty U.S. states. If the device detects a concentration over the legal limit, then the car will sound an alarm. Alcohol ignition interlock devices are already used successfully in all 50 states as a component of DUI sentencing or as a condition for having a license reinstated after a DUI. ---------------------------------------­----------------------------------------­--------------- Next Media Animation’s News Direct service provides daily, high-quality, informative 3D animated news graphics that fill in for missing footage and help viewers understand breaking news stories or in-depth features on science, technology, and health.
