英文摘要：

A device capturing six-dimension information of a helical spring deformation is designed. The helical spring is fixed on the base of the device, by applying a force on the top of the spring, and then the six-dimension information of the spring’s deformation is obtained by an ad hoc sensing technology. The principle of this sensing technology is described, and the circuit detecting the strain of the spring wire surface is designed. Finally, an experimental system of the device capturing six-dimension information is developed, and the experimental result verifies the feasibility of this method.
