Abstract
According to the present invention there is provided a strain sensor apparatus comprising, two or more strain sensors each of which is capable of measuring strain and each of which is configured such that it can be arranged to cooperate with a structure to be monitored so that strain in the structure can be detected by a strain sensor, and one or more position references which is/are arranged in a predetermined position relative to the two or more strain sensors and wherein the one or more position references are each configured such that they are suitable for cooperating with a measuring means; one or more measuring means which is configured to cooperate with the one or more position references so that the angular orientation of the one or more position references can be determined. There is further provided a corresponding method for sensing strain in a structure.
