Abstract
The aim of this work is to show the possibility to realize accelerometers through 3D-printing technique and to investigate the potentiality of these devices. The feasibility of such accelerometers is studied considering the capability of printers to extrude both insulating and conductive materials. Different types of geometries with different characteristics and performance are carefully analyzed and their advantages and disadvantages are determined. The research focuses mainly on differential capacitive accelerometers, today extremely widespread and that can be realized relatively easily via 3D printing, provided that both insulating and conductive materials can be used with the same printer. The printed sensor has been stimulated on each axis with mechanical oscillations produced by a loudspeaker connected to a signal generator. The output signal from the sensor has been read employing an electronic interface for differential capacitive sensors. The obtained experimental results are in a good accordance with those theoretically predicted.
