Abstract
A flexible measuring ruler includes a flexible ruler body and a measuring device, a conductive layer is disposed on the flexible ruler body, which regularly arranged along a length of the flexible ruler body, a linear resistance of the conductive layer changes regularly along the length of the flexible ruler body; the measuring device includes a data collector and a date processor, the data collector includes a resistance measuring circuit including positive and negative probes, when measuring with the flexible ruler body, the data processor converts a resistance value measured by the data collector into a length value based on a variation rule of the linear resistance of the conductive layer along the length direction of the flexible ruler body. The flexible measuring ruler has a simple structure principle, easy operation and high measurement accuracy.
