The necessity of reliable measurement data assessment in the realm of human life has experienced exponential growth due to its extensive utilization in health monitoring, rehabilitation, surgery, and long-term treatment. As a result, the significance of kinematic biosensors has substantially increased across various domains, including wearable devices, human-machine interaction, and bioengineering. Traditionally, the fabrication of skin-mounted biosensors involved complex and costly processes such as lithography and deposition, which required extensive preparation. However, the advent of additive manufacturing has revolutionized biosensor production by facilitating customized manufacturing, expedited processes, and streamlined fabrication. AM technology enables the development of highly sensitive biosensors capable of measuring a wide range of kinematic signals while maintaining a low-cost aspect. This paper provides a comprehensive overview of state-of-the-art noninvasive kinematic biosensors created using diverse AM technologies. The detailed development process and the specifics of different types of kinematic biosensors are also discussed. Unlike previous review articles that primarily focused on the applications of additively manufactured sensors based on their sensing data, this article adopts a unique approach by categorizing and describing their applications according to their sensing frequencies. Although AM technology has opened new possibilities for biosensor fabrication, the field still faces several challenges that need to be addressed. Consequently, this paper also outlines these challenges and provides an overview of future applications in the field. This review article offers researchers in academia and industry a comprehensive overview of the innovative opportunities presented by kinematic biosensors fabricated through additive manufacturing technologies.

Additive manufacturing/3D printing is praised as revolutionary by many because it enables the decentralized and on‐demand manufacturing of complex shapes. With the ongoing rapid development and increased availability of these technologies, it has become crucial to develop novel materials with unique functionalities for 3D‐printed components. Advances in self‐healing materials have resulted in structures capable of recovering from physical damage through material remendability. By applying self‐healing solutions to 3D printing, researchers are attempting to overcome current barriers such as low mechanical properties, material waste, and printability issues, among others. This review summarizes the current state of research on self‐healing materials used for 3D printing and presents recent progress in the 3D printing of self‐healing components. The particular focus is on the use of intrinsic polymer self‐healing, which is prominent in the published literature. The self‐healing mechanisms of the proposed material systems as well as their composition are highlighted, and their intended application with respect to 3D printing is focused on. The scientific and technological challenges involved in the implementation of self‐healing materials and approaches and the potential functional 3D printing applications of these new materials are also discussed.
