Abstract
An electrical type strain gauge for measuring both micro and macro deformations. The gauge may be constructed from thin films of homogeneously conductive polymers, including soluble polyaniline-based conducting polymers and ion-implanted organic polymers. The gauges are characterized by unexpected piezoresistivity from materials having high bulk resistivity, thermal stability, good flexibility, photoimageability and without adding carbon or metal particulate material to the polymer.
