A textile with an electrically conductive first side and an electrically conductive second side where the two sides are separated by an electrically insulating part of the textile and where the electrically conductivity is provided by a graphene coating on the respective sides and where a capacitance can be formed between the respective conductive sides.

A multibend sensor is able to provide information regarding bending of the sensor data in a manner able to mitigate error propagation. A reference strip and a sliding strip are separated from each other by a spacer. Electrodes are located on the reference strip and the sliding strip. The bending of the multibend sensor will be reflected in the shifting of the sliding strip with respect to the reference strip and the measurements obtained from the electrodes. A finger may be operably connected to the reference strip, wherein the finger extends in the direction of the sliding strip, wherein movement of the reference strip with respect to the sliding strip is translated through the finger.

A detection device detects a mechanical deformation of a high-voltage accumulator of a motor vehicle, and includes: a sensor element, which senses an electrical measurement variable, wherein the sensor element is substantially flat and is attached at least partially to a first component of the high-voltage accumulator; and an evaluation device for analyzing the electrical measurement variable between the sensor element and a second component of the high-voltage accumulator and for outputting a corresponding warning on the basis of the electrical measurement variable, wherein at least one region of the surface of the second component is electrically conductive.

A sensor line for detecting an external influence on a cable is described. The sensor line comprises: a capacitor, a first dielectric, which has a first compressibility and a first permittivity, and a second dielectric, which has a second compressibility and a second permittivity. The first compressibility is smaller than the second compressibility. The first permittivity differs from the second permittivity. The sensor line is configured so that at least the second dielectric is compressible or extensible in the event of a movement of the sensor line, so that a total permittivity, which is composed of the first permittivity and the second permittivity, is variable in the movement of the sensor line. Due to the change in total permittivity, a change in the capacitance of the capacitor can be produced, which is detectable, in order to detect the external influence on the cable.

Methods and systems suitable for fabricating multi-layer elastic electronic devices, and elastic electronic devices formed thereby. A method of fabricating an elastomer-based electronic device includes printing a first liquid material and then a second liquid material on a fabric substrate that comprises fibers. The first and second liquid materials are sequentially printed with a three-dimensional printer that directly prints the first liquid material onto the fabric substrate so that the first liquid material wicks through some of the fibers of the fabric substrate and forms a solid matrix of an elastomer-based composite that comprises the matrix and the fabric substrate, after which the three-dimensional printer directly prints the second liquid material on the elastomer-based composite to form a film thereon. The elastomer-based composite and film are electrical components of the elastomer-based electronic device.
