Abstract : Nine elastomer strain gage modules were fabricated and evaluated. Each module contains four independent sensing elements; three of the elements are orthogonal and the fourth element is skewed at an equal angle from the orthogonal elements. In manufacturing unidirectional, surface mountable gages, a large number (about 50 percent) of devices fail during fabrication steps. As might be expected, only about one in ten of the four-element modules emerges from fabrication with all elements operational. (Author)
