Embodiment Construction

[0022] Considering the annotated figures and according to the numbering adopted, it is possible here to comment on a preferred but non-limiting embodiment of the invention consisting of a large-area stretchable pressure sensor (hereafter referred to as 1 ) for a textile surface, And is typically performed by a "roll-to-roll" process known for producing electronic devices in a variety of rollable, flexible substrates, such as textiles.

[0023] In a preferred embodiment of the present invention, it can be obtained from figure 1 It can be seen that this sensor 1 consists of a soft, stretchable and elastic substrate 2 of the textile type, on which conductive ink or paste is printed in the form of main tracks 3a, so that on said main tracks 2 A plurality of pressure sensitive points 4 printed in a circular shape and made of piezoresistive ink or paste, on which are partially printed secondary traces 3b made of conductive ink or paste, avoiding between the aforementioned traces 3a,...

Abstract

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 characterised 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.

Description

technical field [0001] The object of this patent application is a documented large-area stretchable pressure sensor for textile surfaces, where a large area will be understood as having 2 Any surface with a larger area. Notably, due to the mechanical properties of all materials and textile supports, due to its use of conductive inks and stretchable piezoresistive (varistor) and deposition (deposition) systems, the pressure sensor object of the present invention includes multiple properties such as flexibility Mechanical properties, including total wrinkle, stretchability and elasticity of the sensor surface. Even in the state of kneading and extensibility, the pressure sensor retains its functionality, allowing it to recover its shape once the received external deformation is over, thanks to the elastic properties of the support. [0002] More specifically, the large area pressure sensor has multiple traces of conductive ink or paste on which are printed multiple detection p...
