Surface Acoustic Wave (SAW) sensors are diffused in the market due to their characteristics in terms of sensitivity, power consumption, attitude for being organized in arrays and wireless networks. In this work is reported about the development and the response towards ethanol of a sensing device realized by inkjet printing a poly(methacryl)acid (PMA) layer on a TO39 packaged SAW resonator working at a nominal frequency of 433.9 MHz. This kind of package allows to be easily opened for sensing film deposition on the piezoelectric substrate to develop a SAW-based sensor. © 2012 The Authors. Published by Elsevier Ltd.
