Gas and Vapor Sensors on Paper

Sensors on paper have been proposed and fabricated to identify gas or vapors (chemicals). Traditional sensors are based on hard substrates such as silicon. Sensors fabricated on paper are cheaper, foldable, flexible, and bio - degradable. Paper electronics is an emerging area. Logic devices, memory, RFID (radio-frequency identification) tags, etc. have been demonstrated. Sensors on paper will be another building block to achieve complete, true paper electronics.
