Abstract
A tamper proof transdermal alcohol content monitoring device is made up of analog and digital sides which are securely attached to the human subject to be monitored. The analog side has a sampling circuit which draws a measured insensible skin perspiration sample from the skin of the subject and measured with an electrochemical fuel cell. A distance measurement of the device from the skin of the subject and temperature of the sample are monitored along with the transdermal alcohol content, and converted to digital signals which are transmitted to a modem when the monitor is in proximity to the modem. The signals are stored in the modem and uploaded to a central monitoring station. Automatic alerts may be sent from the central monitoring station to a supervising agency. The supervising agency may also access the information through secured dedicated websites via the Internet.
