Transdermal Alcohol Detection System through Measurement of Capacitance Change in a MEMS Device Year One

The proposed research develops a transdermal alcohol detection system. The system is comprised of an array of polymer based MEMS sensors and a sensor measurement circuit. The system analyzes gases exuded from the skin - the gases are chemical mixtures that may (or may not) contain ethanol. No known polymers respond only to ethanol; however, each polymer in the array creates a unique response to the presence of ethanol. When examined together - like a series of simultaneous equations - sensor responses accurately indicate the presence of ethanol.
