“…Shape-memory alloys (SMAs) have been suggested as a potential solution to the issues associated with conventional ankle–foot orthoses, which are typically characterized by their weight, bulkiness, and limited functionality. The superiority of SMA-based AFOs is demonstrated by their lighter weight and more streamlined design, due to their higher power-to-weight ratio [ 76 ]. A study conducted by a researcher incorporated the use of superelastic wires and the installation of 14 plastic pulleys using screws and spacers [ 77 ].…”

The aim of this work was to study the different types of passive articulated and non-articulated ankle–foot orthoses for gait rehabilitation in terms of working principles, control mechanisms, features, and limitations, along with the recent clinical trials on AFOs. An additional aim was to categorize them to help engineers and orthotists to develop novel designs based on this research. Based on selected keywords and their composition, a search was performed on the ISI Web of Knowledge, Google Scholar, Scopus, and PubMed databases from 1990 to 2022. Forty-two studies met the eligibility criteria, which highlighted the commonly used types and recent development of passive articulated and non-articulated ankle–foot orthoses for foot drop. Orthotists and engineers may benefit from the information obtained from this review article by enhancing their understanding of the challenges in developing an AFO that meets all the requirements in terms of ease of use, freedom of movement, and high performance at a relatively low cost.

The preparation of a thin hard coating is the main challenge in the coating of NiTi articles. To achieve a thin coating of titanium nitride (TiN) on NiTi substrate, physical vapour deposition (PVD) was proposed in this study. Deposition of TiN coating was carried out at the nitrogen flows of 0.79 and 0.93 Pa. Phase composition, thickness, porosity, adhesion strength, hardness, and tribological properties of the TiN coatings were evaluated. The adhesion of the coating to the substrate was acceptable. Increasing of the gas flow resulted in a higher thickness (1 μm), lower porosity and higher adhesion strength. On contrary, the samples prepared with the lower gas flow showed higher hardness and elastic modulus. The coated samples showed smaller width of wear, lower wear rate and lower friction coefficient in comparison to the substrate. The delamination and adhesive wear mechanisms govern the wear process.
