This article focuses on the design, development and fabrication of the strain measuring sensor and its interface with a data acquisition system which converts the force applied on the rigid frame of the leg to a voltage potential which can be used for further processing. The sensor element used for the experimentation is a transducer class of strain gauge which are open gauges with a constant alloy pattern constructed on a thin polyimide-film backing and is pasted on a GI sheet. The strain gauge is then interfaced with a Wheatstone bridge and is interfaced with a National Instruments SCC-68 interface card and PXI-6259 DAQ system.
