The sensor portion includes a sensor element, a sensor main body, and a grounded terminal. The sensor element is disposed in a sensor placement region which is located between the conductive member and the facing member and in which a distance between the conductive member and the facing member is shortest.

Abstract: 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.

Abstract: Embodiments of a system and a method for measuring cementitious board during its continuous manufacture can be used online in a continuous manufacturing process to effectively determine the degree to which cementitious slurry has set (e.g., expressed as percent hydration) at a predetermined location, such as, near a cutting station, for example. A compression assembly can be used to compressively engage the cementitious board in a controlled manner as it passes by the compression member along the conveyor between the forming station and the cutting station. A force gauge can be associated with the compression member to measure the resistance force exerted by the cementitious board in response to being compressed by the compression member. The resistance force can be correlated to a set characteristic of the cementitious board, such as a numerical value of percent hydration of the cementitious slurry of that particular portion of the cementitious board.
