Procedia Engineering, 2016•ElsevierThis contribution deals with preliminary studies for touchless interaction based on capacitive
sensor technology. The presented measurement system is able to measure capacitances in
a range of a few fF to several pF (eg, caused by human finger interaction). The main focus is
the development of an intelligent shielding strategy in combination with a specific geometry
of an electrode array in order to circumvent interference artefacts. This design ensures a
rapid prototyping capability and is easily adaptable to different substrate materials.
