Abstract:
The present disclosure provides a textile fabric containing a first electrically conductive thread (10) and a second electrically conductive thread (20), the first electrically conductive thread (10) and the second electrically conductive thread (20) crossing at a first crossover point (1), wherein the textile fabric further contains an electrical connector (50) establishing an electrical connection between the first electrically conductive thread (10) and the second electrically conductive thread (20). The electrical connector (50) contains a first contact pad (11) in electrical contact with the first electrically conductive thread (10), a second contact pad (21) in electrical contact with the second electrically conductive thread (20), and a first stretchable electrical interconnection (51) connecting the first contact pad (11) with the second contact pad (21). The first contact pad (11) and the second contact pad (21) are provided at a location different from the location of the first crossover point (1). The present disclosure further provides methods for electrically interconnecting crossing electrically conductive threads of textile fabrics.
Abstract:
A method of manufacturing an electronic textile (1) comprising the steps of: providing a textile carrier (2) comprising a plurality of conductor lines (6a-b); releasably attaching (101) the textile carrier (2) to a rigid support plate (20); providing (102) a conductive substance on the textile carrier (2) in a pattern forming a plurality of sets of connection pads (5a-b) on the textile carrier (2), each set of connection pads defining a component placement position for placement of an electronic component (3), and each set of connection pads (5a-b) comprising a connection pad overlapping one of the conductor lines, the connection pad having a connection pad length (L cp ) in a direction parallel to the conductor line and a connection pad width (W cp ) in a direction perpendicular to the conductor line, wherein the connection pad width (W cp ) is at least one percent of an extension (W tc ) of the textile carrier (2) in the direction perpendicular to the conductor line; automatically placing (103) electronic components (3) at the component placement positions; curing (104) the conductive substance to attach the electronic components (3) to the textile carrier (2), thereby forming the electronic textile (1) and removing (105) the electronic textile from the rigid support plate.
Abstract:
The invention relates to an electronic network comprising a row of two or more electronic components (121, 122, 123) each having an input terminal (131, 141) and an output terminal (132, 142). All input terminals are interconnected with a conductive input line (151), and all output terminals are interconnected with a conductive output line (152), the input and output lines having a uniform and substantially the same electrical resistance per unit length. The input line is arranged to allow electric charge to flow to each electronic component via the input terminal (131) of the first electronic component (121), and the output line is arranged to allow electric charge to flow away from each electronic component via the output terminal (142) of the last electronic component (123). The electronic network enables a uniform performance of the electronic components, particularly when the input and output lines have a relatively high electrical resistance. The electronic network is therefore particularly suitable for use in an electronic textile (100), wherein the input and output lines are electrically conductive yarns that are interwoven in a textile carrier (110) on which the electronic components are mounted.
Abstract:
An active implantable medical device (AIMD) comprising an implantable electronics module and a tissue interface. At least one of the electronics module and the tissue interface comprises an electrically non-conductive, biocompatible and needle-piercable base having one or more biocompatible electrically conductive strands of conductive filaments stitched to the base. As used herein, stitching a conductive filament to a base refers to sewing, embroidering or otherwise securing the filament to the base through the use of hand or machine needlework.

Abstract:
An electronic textile (300;400) comprising a textile substrate (102) having at least a first set of textile substrate conductors (202a-f,203a-e;403) each being arranged to enable electrical connection of an electronic device (209;401) thereto.

The power distributing structure (301;405) has a substantially lower resistivity than each of the textile substrate conductors (202a-f,203a-e;403) to allow for an even distribution among the textile substrate conductors of power from the external power source (210).
