Summary:This paper presents a new distributed parameter element (DPE) method for modeling a 2D or 3D physical field, which belongs to a class of scalar linear partial differential equations. The irregularly shaped physical-field is divided into distributed elements. Each element satisfies the conservation law and boundary conditions; and the divergence theorem is applied on each element to account for the geometry property. The physical field is formulated in state-space representation providing a basis for the subsequent steady state and transient response analyses. The DPE method has been numerically verified by solutions against results computed using commercial finite element analysis (FEA) software. As an illustrative application, the effects of different stimulation designs on the activating function in the forearm were investigated using the DPE method. Validated experimentally using a commercial electrical muscle stimulator and recording glove to observe the bending angles of a ring finger, the findings have led to a novel double-pair design that improves the stimulation effectiveness by relaxing the assumption of known nerve position.
