SCRAMSecure Continuous Remote Alcohol Monitor
• Transdermal alcohol testing
• Tamper‐resistant
• Court‐mandated
• Readings every 30 minutes, uploaded daily
• Good success rate at enforcing abstinence
E. Bryant
Uses for alcohol biosensors• Criminal justice system
• Alcohol research
• Public safety‐ pilots, Metro drivers, doctors, police
• Medical conditions in which alcohol is a confounding factor; HIV patients + HAART
• Pregnant women
• To monitor relapse
• Wearable, comfortable, inconspicuous, inexpensive.
• Ability to remove for activity (depending on application)• Subject identification:
Biometric, facial, or voice recognition• GPS (when needed)
• Ability to interpret, transmit, and record data.
• Ability to verify standardization and functionality.
• Power source‐ dependable, rechargeable.
• Microelectronic miniaturization
Many of these aspects are available in devices that are on the market, but not with alcohol detection.
What is needed to improve upon current alcohol monitors?
Alcohol detection technology
• Electrochemical fuel cell
• Near infrared
• Mid‐range infrared
• Semiconductor
Wearable, discreet, compact
Able to record, to send a signal to a readable device
Subject identificationFace, biometric signature
Miniaturization of electronics Light sourcePower source
• This generation self‐monitors their every physiological parameter.
• Fit‐bit, Jawbone
• Heart monitors, oximeters
• Cell phone apps…for everything
