Strain Measurement of Extensible Materials by Image Sensor PC Mouse

Abstract

It is shown that the strains of highly extensible materials such as elastomeric materials and polymer composites can be accurately measured by an image sensor PC mouse which is now becoming more and more popular as a computer input device. While in computer environments, mouse moves on the fixed pad and it measures its own movement, in this study, the movement of the specimen is measured by the mouse fixed in space. Conversion formula of strains from the Eulerian description to the ordinary Lagrangian one is presented.
