This review and orientation to strain gage technology presents the historical development of the bonded foil resistance strain gage as well as modern design and selection criteria for the successful use of strain gages in smart structure technology. Discovered in 1865 by Lord Kelvin, the principle of using resistance change in conductors to measure strain has existed in its present form of the foil strain gage since the late 1950s. Since then, advances in manufacturing and applications techniques have made the bonded foil resistance strain gage one of the most economical and easy to use sensors available for direct measurement and transducer applications alike. Millions are produced and use each year throughout the world. The factors affecting strain gage design and construction include of foil alloy, backing, pattern, and temperature characteristics. Over 250,000 unique strain gage constructions are possible, each particularly suited to a specific set of application conditions. The effect of each of these factors on smart structure performance is considered.
