A potentiostat data link (PDL) unit is provided which can remotely monitor the formation and growth of cracks in metal structures. A PDL includes a sealed box containing two or more modified potentiostats, a power supply, a CPU, a memory device, and computer networking capability. The PDL can be mounted in a remote, difficult-to-access location. Each potentiostat has a lead to a sensor affixed to a structure to be analyzed for the presence of growing cracks due to metal fatigue in a metal structure.

Potentiostat data link

A method of making a resilient prosthetic/orthotic component, particularly a shank for a lower extremity prosthesis in which the shank includes multiple sections which are unbounded in one or more portions of each other, and wherein the shank sections incorporate at least one voids and inserted materials between one or more shank sections to enhance shank flexibility while reducing stresses which can cause premature failure.

A method for determining a fatigue status of a growing crack in a substrate. An electrochemical sensor device is provided and includes an electrode formed from a stainless steel mesh. The electrochemical device has a bottom surface that contacts the substrate. The bottom surface is coated with an adhesive layer, and a release paper is attached to the adhesive layer. The release paper is separated from the adhesive layer, thereby exposing the adhesive layer. The electrochemical sensor device is secured to the substrate by bringing the adhesive layer in contact with the substrate and thereby forming an electrolyte cavity bounded in part by the substrate. The adhesive seals the bottom surface of the device to the substrate in order to prevent leakage of electrolyte from the cavity. The cavity is filled with the electrolyte. When the substrate is subjected to cyclic loading, the fatigue status of the growing crack in the substrate is determined in accordance with a measured current between the reference electrode and the substrate.
