Abstract:

The article describes Plantograf V18, a planar tactile transducer, which converts the applied pressure into electric signal and enables a graphical presentation of the measured data; the new version V18 comes with some significant improvements and modifications. The device may be used everywhere where the pressure distribution between an object and surface is to be determined, e.g. in medicine or automotive industry. The article contains the detailed description of the transducer design and its electronic control circuits, as well as the yet unpublished measurements of pressure sensitivity with 3.5 mm electrodes.

Abstract:

The article deals with tactile sensors with circular electrodes in which conductive ink was used as a converter converting pressure into an electric signal. The article briefly describes theoretical background of this issue and presents several appropriate converters, from which the tested ink was selected. The measurement process is described in detail, and subsequently the dependence of resistivity on the thickness of the deposited ink layer is studied and the properties of various setups were compared. Finally, the results are summarized and the main issues are pointed out.
