SOAR High School
Lancaster, CA
Alcohol level detection bracelet


The SOAR High School InvenTeam is inventing a blood alcohol measurement wristband that utilizes an original apparatus located on the underside of the wrist. When the user blows onto the sensor, the presence of ethanol will trigger an analog voltage charge that is converted into a light-emitting diode, indicating how close the user is to the legal drinking limit. The wristband will help reduce the problem of drinking and driving.
