Abstract
Earlier investigators have shown that discontinuous metal films have higher gauge factors (defined as the ratio between relative resistance change and deformation) than the corresponding bulk metals. The effect is particularly pronounced for gold. The present study is focused on some properties of gold films that are important for strain gauge applications. A voltage dependence of the film resistance described by previous authors has been avoided by a new contact technique. Other parameters that have been measured are gauge factor and its variation, temperature coefficient of resistance, aging effects and humidity effects. It is concluded that the basic limitation for wide range applications is the problem with long term stability. Potential applications where this is not important are suggested.
