Electrochemical sensor strips were one of the first devices to become a global success in what might now be termed the printed electronics industry. Since their creation some 20 years ago, printed sensor strips are used extensively for a range of clinical and biomedical diagnostic applications and are, themselves a multi billion dollar industry. To date, they have principally exploited screen printing and lamination processing. The range of available sensors is expanding further due to the availability with a wider range of functional, processable materials including organic, metallic and hybrid materials. The range of processing methodologies is also expanding to include other forms of printing including inkjet. My research group are developing a number of printed chemical sensors and biosensors for a range of industrial and biomedical applications. These sensors have a significant reliance on new materials such as conducting polymers deposited using inkjet printing. Applications for these include clinical biosensors, diagnostic breath monitoring devices and, most significantly are now being integrated with other printed electronic components such as batteries, displays and organic circuits to create the first truly integrated, printed smart systems. Current progress on these technologies will be highlighted.
