The overall goal of this foresight on sensor technologies was to provide scenarios for future developments in sensor technology in terms of the technology itself, its application and relevant markets for the period 2000–2015. This was to provide a decision support tool to prioritise research and development and to guide the commercialisation of sensor technology in the near future. It was also intended to develop and maintain networks of expertise within the sensor technology community and to test elements of technology foresight methodology applied to a narrow technology domain.
