The development of low-cost, robust, reproducible optical chemical sensors using inkjet printing

The optical sensor industry is forseen to be- come a $4 billion market worldwide within 10 years. This projected figure suggests the incorporation of wireless sensor networks into our daily lives. In order to achieve this, many hardware requirements have already been met, with many of the world’s top university in- volved in wireless "mote" development. The objective of this study is to prove that inkjet printed sensors will be compatible with these motes in terms of both accuracy and more im- portantly reproducibility
