A pressure gauge includes a housing and a mechanical sensor placed in the housing for sensing change of the pressure. A characteristic of the sensor varies in correspondence to the change of the pressure. The gauge also includes an optical fiber, at least part of which is in the housing with a first.....

Existing pressure sensing fabrics may involve two portions, i.e., insulating and conductive portions in the fabric, which increases the complexity of the fabric system and more important, and the instablization of the resistance-strain relationship during dynamic deformation which limits the applica.....
