A Flexible and Adaptable Ethanol Vapor Sensor Derived from an Adhesive Tape

Developing a flexible and adaptable sensor for the detection of ethanol vapor is important for many healthcare and environmental applications. Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate has shown excellent electrical properties and is easily processed. Adhesive tapes are used widely in many applications due to their excellent adaptability to various environments. Here, we show, for the first time, the development of a flexible adhesive tape-based sensor for the detection of ethanol vapor. The sensor shows a detection range of 5%-60% of saturated ethanol vapor and a rapid measuring time of about 15 s with an excellent linear correlation to the commercial available sensor. It is expected that these results could open exciting opportunities for fundamental studies of construction of new types of flexible sensors as well as serve in various healthcare, environmental, and defense applications.
