A system of fabric-based devices designed as transistors with tri-state behavior that can measure any geometries on 2D and 3D surfaces. The devices are constructed from layers of conductive materials and flexible sheets that allow signals to selectively cross between layers. Multiple layers of conductive signals can be achieved by controlling the tension of the top and bottom thread, and interlayering conductive, semiconductive, insulating, and semi-porous materials around a sensing layer. The layers can be further modified to include folds and cuts that allow for 2D and 3D bending, stretching, twisting, and curves. Large sheets of devices can be organized into grid-like matrixes, with signal wires connected in a multiplexed fashion to minimize the amount of threads to simplify construction and device communication to a central processing unit.

A flexible substrate including a conductive path formed on a side of the flexible substrate from a flexible conductive thread attached to the substrate and an electronic component attached to the same side of the substrate as the conductive path and electrically connected to the conductive path and having an adhesive on the same side suitable for adhering the flexible substrate including the conductive path and the electronic component on a region of skin of a user's body.

A buttonhole sewing guiding device of a sewing machine includes a buttonhole presser foot unit disposed on a presser foot holder of the sewing machine, and a sensing unit disposed on the buttonhole presser foot unit. A presser frame of the foot unit is movable relative to a sliding member between first and second sewing positions set in accordance with an operating distance that corresponds to a size of a button to allow first and second triggering members to initiate a sensing module for controlling operation of a sewing needle.

The disclosure relates to a sensor which is produced by stitching it onto a carrier using threads. The stitching forms a first electrode, a second electrode and a covering layer. The covering layer can be used to produce an electrically conductive connection between the first electrode and the second electrode, at least if a force acts on the covering layer and presses at least one part of the covering layer against a part of the first electrode and of the second electrode. This force can be caused by a pressure locally exerted on the covering layer and/or by bending of the covering layer or of the carrier. The entire sensor and, in particular, the first electrode, the second electrode and the covering layer are produced solely by being stitched onto a common carrier. The sensor can be produced in a particularly simple and cost-effective manner and is robust.

An apparatus for feeding plate-shaped functional elements to a sewing or stitching machine comprises a first guide rail which extends in a longitudinal direction between a first end and a second end and which has a first delimiting surface and a first guide surface extending transversely with respect to the first delimiting surface, a second guide rail which extends in the longitudinal direction between a first end and a second end and which has a second delimiting surface, facing the first delimiting surface and extending parallel to the first delimiting surface, and a second guide surface extending transversely with respect to the second delimiting surface in the direction of the first guide rail; and a transporting device configured to move a functional element resting on the first and the second guide surface from the first end of the guide rails in the direction of the second end of the guide rails.

A process for attaching a functional flexible element on a flexible support without the use of adhesive composition. The process comprises a step of depositing a functional flexible element on a flexible support, a step of stitching along a zigzag line of at least one binding yarn on either side of the functional flexible element along the functional flexible element while retaining the functional flexible element on the flexible support. The first binding yarn(s) are stitched into the flexible support at stitching points to a depth of less than the thickness of the flexible support.
