Large-area extensible pressure sensor for textiles surfaces

摘要

The invention relates to a large-area extensible pressure sensor for textile surfaces, of the type comprising a support on which a conductive ink is printed which can transmit a printed electrical signal by any known printing technique. More specifically, the pressure sensor is characterized in that said support is flexible, extensible and elastic, and a plurality of main tracks of extensible and elastic conductive ink or paste are printed on said support; on said plurality of main tracks a plurality of piezoresistive paste or ink depositions acting as pressure sensing points are printed, and each of these depositions are linked to a secondary extensible and elastic conductive ink or paste track, which is also printed on said support, resulting in all tracks, primary or secondary, being connected to a control system without crossing each other.
