This research is aimed at: l. establishing the efficacy of TRIBOSENSING         as a technique for nondestructive, and in-process evaluation of                 materials; and 2. developing a theoretical and practical technical base         for the field of tribosensing.  Conceptually, the use of a tribosensing         system in an industrial process involves measuring and analyzing a              combination of tribomechanical, tribothermal, triboelectrical,                  triboacoustic, and other tribological effects simultaneously during the         rubbing of two surfaces in order to determine any material quality              parameter of interest.  The potential use of tribosensing in                    manufacturing is very diversified - some examples of applications are:          self-diagnostic machines, intelligent sensors for process control, in-          process materials characterization, and robot tactile sensing.  To              develop a practical, automated system based on the tribosensing concept,        several specific research issues are identified: 1. selection of sensors        and sensing materials; 2. optimization of the design of the sensing             probe; and 3. development of tribosensing models and a unified signal           processing methodology.  To establish the knowledge base for the optimal        design of tribosensors, selected experimentation, coupled with                  theoretical analysis of the physics of the underlying tribological              phenomena, will be pursued.  To develop a unified methodology for               analyzing tribosensing data, the applicability of the recent advances in        the field of digital signal processing will be critically examined.  The        significance of this proposed                                                   research lies in the development of a novel, nondestructive, on-                line sensing technique for a myriad of industrial applications.                 Furthermore, the research explores the idea of quantifying and                  utilizing the "information content" in tribological phenomena,                  which in itself is a unique approach to furthering our                          understanding of the physics of tribology.
