Definitions

  • the invention relates to connectors for connecting sensors that can be placed in contact with or close to human skin and monitor physical, physiological, or clinical signs, especially wearable sensors, and measurement devices.
  • the interconnections need to be via a solid metallic or polymeric surface to allow robust and reliable electrical connection for both power delivery and data/signal collection.
  • the textiles/electronics interface is often the most common aspect of sensor failure. Due to the use of incompatible materials and manufacturing techniques, failure at this interface occurs in a high number of textile based sensor systems. The mechanical degradation due to laundering and water ingress during use are also key contributors to this failure.
  • snap connectors formed of hard plastic components allow power supply and data to be located in one place. Whilst this arrangement allows for a consistently secure connection over repeated applications and for extended periods, wearer comfort and compliance present major difficulties when using this type of connection.
  • a conductive polyurethane adhesive tape This type of tape provides excellent connection and good flexibility.
  • TPU is a smooth and mostly non-porous polymer.
  • the non-porous properties often lead to build-up of moisture, which can contribute to device failure and user discomfort.
  • Smooth materials are also irritable to skin, because human skin does not like the sensation of being in contact with very smooth surfaces.
  • connection can be either mechanical or magnetic. They are typically robust and repeatable as connection systems. It is noted that mechanical failure can occur at these interconnections due to the flexible nature of the textile and the incompatibility of hardness and textile durability. Such interconnections offer a high risk of user injury during use or during connection. These metallic connections are often very small in area and when a large force is applied skin and tissue damage are likely.
  • Polymer surfaces are used in two distinct areas.
  • a hard polymer surface is often used to anchor the metallic connections. Such surfaces can allow for enhanced connection accuracy and hence better power distribution and data collection.
  • connection system for use with a textile-based sensor that allows for robust connection and power transfer but which does not compromise user comfort or compliance.

  • the sock provides a durable, convenient, and integral sensing apparatus with connector. Furthermore, the sock can be washed and worn easily without requiring removal of the connector, and takes up a similar amount of space as a conventional sock due to the flexibility and size of the connector.
  • the connector has a number of advantages. In particular, the mechanical failure of the connector is less likely, in contrast to previously where there may have been incompatible structures, and the connector is much more mechanically durable throughout the wearing and washing processes, and does not need to be removed during washing.

Abstract

L'invention concerne une chaussette pour surveiller une donnée de sortie physique ou physiologique d'un porteur. La chaussette est constituée d'un textile tricoté et comprend également: une pluralité de capteurs, chaque capteur étant incorporé intégralement dans le textile et constitué de fils conducteurs qui sont tricotés dans le textile, les capteurs étant configurés pour détecter une sortie physique et/ou physiologique du porteur par détection d'une variation de la position, de la composition, de la résistance de contact entre, un déplacement et/ou une distance entre les fils conducteurs dans les capteurs; un connecteur pour fournir une interface à base de textile entre un module de collecte de données externe et les capteurs; et une pluralité de traces électriquement conductrices qui s'étendent depuis les capteurs jusqu'au connecteur, chaque trace transmettant une puissance et/ou des données à destination ou en provenance de chacun de la pluralité de capteurs. Le connecteur comprend une bande de forme allongée fabriquée à partir d'un textile et divisée en une première partie et une seconde partie. La bande de forme allongée comprend une première couche, une deuxième couche et une troisième couche. Le connecteur comprend en outre une pluralité de lignes de transmission, et une pluralité de contacts brodés. La première partie relie le connecteur à la chaussette et est configurée pour se connecter à des parties terminales des traces. La seconde partie n'est pas connectée à la chaussette et permet une connexion flexible avec le module de collecte de données externe. Une première extrémité de chaque ligne de transmission est en connexion électrique avec une partie terminale d'une trace, et une seconde extrémité de chaque ligne de transmission est configurée pour être connectée au module de collecte de données externe. Les lignes de transmission sont comprises dans les première et troisième couches de la bande de forme allongée, la deuxième couche est une couche isolante disposée entre les première et troisième couches, et chacun de la pluralité de contacts brodés est situé au niveau de la seconde extrémité d'une ligne de transmission correspondante.
