Linear polyamides, known as nylons, are a class of synthetic polymers with a wide range of applications due to their outstanding properties, such as chemical and thermal resistance or mechanical strength. These polymers have been used in various fields: from common and domestic applications, such as socks and fishing nets, to industrial gears or water purification membranes. By their durability, flexibility and wear resistance, nylons are now being used in addictive manufacturing technology as a good material choice to produce sophisticated devices with precise and complex geometric shapes. Furthermore, the emergence of triboelectric nanogenerators and the development of biomaterials have highlighted the versatility and utility of these materials. Due to their ability to enhance triboelectric performance and the range of applications, nylons show a potential use as tribo-positive materials. Because of the easy control of their shape, they can be subsequently integrated into nanogenerators. The use of nylons has also extended into the field of biomaterials, where their biocompatibility, mechanical strength and versatility have paved the way for groundbreaking advances in medical devices as dental implants, catheters and non-absorbable surgical sutures. By means of 3D bioprinting, nylons have been used to develop scaffolds, joint implants and drug carriers with tailored properties for various biomedical applications. The present paper aims to collect evidence of these recently specific applications of nylons by reviewing the literature produced in recent decades, with a special focus on the newer technologies in the field of energy harvesting and biomedicine.

“…They suggested that the combination of the fiberorthocryl resin provided the best composite with the highest average tensile strength. In addition to prosthetic running blades, some studies (11,16,35)have reported on the design of lower limbs utilizing various materials. However, the design and selection of materials for running blades have not received attention and thus very few research works have been reported.…”

This study focuses on the development of a reliable prosthetic running blade primarily composed of carbon fiber. The reliable performance of novel prosthetic running blades has been evaluated by mechanical testing and finite element numerical modeling. The experimental analysis confirmed that these blades exhibit superior suitability for high-impact activities, demonstrating reliable load-bearing capacity and effective shock absorption properties. The tensile testing exhibited a linear elastic behavior of the composite material up to a strain of 0.075 mm/mm. Further, it was found that stress concentration areas and fracture points within the blade structure. Furthermore, numerical results revealed a maximum deflection of 29.60 mm that the blade can achieve. The kinetic energy loss during impact demonstrated an 8.5% decrease in blade kinetic energy, with the highest loss occurring at Vy = 30 m/s. Ultimately, this research aims to enhance the reliability, durability, and safety of prosthetic running blades, empowering athletes to reach new heights in sports.
