Abstract: A sensor comprising a plurality of layers, comprising a first mask layer; a second mask layer; a third mask layer disposed between said first and second mask layers and defining an aperture; and a first conductive layer disposed between the first mask layer and the third mask layer; a second conductive layer disposed between the second mask layer and the third mask layer; and a separator layer extending across the aperture in the third mask layer, said separator layer being configured to separate the first and second conductive layers when no pressure is applied to the sensor and to allow electrical contact between said first and second conductive layers during a mechanical interaction with said sensor, wherein each mask layer is formed from an electrically insulating material and has at least one side attached to another of said mask layers by adhesive.

Abstract: A sensor having a three layer construction comprising a first knitted conductive textile plane, a second conductive textile plane and an intermediate separating plane penetrable by the first knitted conductive textile plane to allow the first conductive textile plane and the second conductive textile plane to make electrical contact under a mechanical interaction. The intermediate separating plane defines structural endpoints from which the first knitted conductive textile plane deforms towards the second conductive textile plane under a mechanical interaction. The first knitted conductive textile plane has conductive yarn knitted to form a repeating pattern of stitches each comprising a stitch looping portion SLP having a looping portion footprint LPF. Within the sensor, there is at least one of a plurality of described dimensional relationships between stitches of the first knitted conductive textile plane and structural endpoints of the intermediate separating plane.

Abstract: A method of interfacing an electronic device to a manually operable fabric controller forming part of a personal item, such as an item of clothing or bag. A set of interface devices, each comprising a housing enclosing a processing circuit with analogue ports and control ports, and supporting a first physical interface connected to analogue ports and connectable to a fabric sensor and a second physical interface connected to control ports and connectable to a specific type of electronic device. In this way, it is possible for different electronic devices to be controlled by operation of the fabric sensor supported by the personal item. A method of establishing a music-enabled item of clothing or bag. The identification of an appropriate interface device is facilitated at locations where electronic devices or accessories are made available. The fabric sensor may be removable from the personal item.
