The implantable electronic devices have attracted great attention for solving clinical problems ranging from monitoring psychological states to electro‐organ transplantation. The ongoing challenges are the selection of suitable materials in a target device configuration for biomedical applications. To address the ongoing challenges, there are several interesting questions: what types of electronic materials can be used as the implantable electrodes? What types of materials can be used as the substrates for the implantable electronic devices? What types of materials can be used as membranes and encapsulations? What types of device configurations are there for implantable biomedical applications? What types of applications are for implantable electronic devices? This review will highlight the attempts for addressing these questions. This review will explore the fundamentals and practical aspects of a variety of materials and their biomedical applications in implantable electronic devices. It is anticipated that this review could provide new opportunities for the construction of future implantable electronic devices, as well as related applications for disease diagnosis and therapy.

“…Gold is used in restorative dentistry for implants and fillings, gold wire fixings, and supports (48); in ocular prosthetics (49)-particularly for upper eyelid implant surgery (46); in endovascular stents (46); and as soluble injectable compounds to alleviate rheumatoid arthritis and to treat/prevent bacterial infections (50). Properly installed, gold dental implants last the longest (51). Gold nanoparticles exhibit different physical and chemical properties than bulk gold because their large surface-to-volume ratio makes them more reactive; consequently, a wide range of functionalized gold nanoparticles have been explored for therapeutic and diagnostic applications (52).…”

Additive manufacturing's attributes include print customization, low per-unit cost for small- to mid-batch production, seamless interfacing with mainstream medical 3D imaging techniques, and feasibility to create free-form objects in materials that are biocompatible and biodegradable. Consequently, additive manufacturing is apposite for a wide range of biomedical applications including custom biocompatible implants that mimic the mechanical response of bone, biodegradable scaffolds with engineered degradation rate, medical surgical tools, and biomedical instrumentation. This review surveys the materials, 3D printing methods and technologies, and biomedical applications of metal 3D printing, providing a historical perspective while focusing on the state of the art. It then identifies a number of exciting directions of future growth: ( a) the improvement of mainstream additive manufacturing methods and associated feedstock; ( b) the exploration of mature, less utilized metal 3D printing techniques; ( c) the optimization of additively manufactured load-bearing structures via artificial intelligence; and ( d) the creation of monolithic, multimaterial, finely featured, multifunctional implants.

“…Commonly used metal materials include pure titanium, titanium alloys, cobalt-chromium alloys, and stainless steel [28]. In addition, expensive metals [29,30] and degradable metals [31,32] are also suitable. ISO 13782: 1996 formulated the required characteristics of biomedical metallic materials, including chemical composition, microstructure, and mechanical properties, which provides the principle for the selection of implant materials.…”

“…Additionally, some precious metals have a beautiful color, very stable chemical properties, and excellent biocompatibility. They are widely used in dental implants, such as gold, platinum group metals (platinum, palladium), and silver and their alloys [30]. In general, precious metal dental materials often contain a variety of metals, taking into account the cost of the material and the performance requirements of the implant.…”

Metals have been used for orthopedic implants for a long time due to their excellent mechanical properties. With the rapid development of additive manufacturing (AM) technology, studying customized implants with complex microstructures for patients has become a trend of various bone defect repair. A superior customized implant should have good biocompatibility and mechanical properties matching the defect bone. To meet the performance requirements of implants, this paper introduces the biomedical metallic materials currently applied to orthopedic implants from the design to manufacture, elaborates the structure design and surface modification of the orthopedic implant. By selecting the appropriate implant material and processing method, optimizing the implant structure and modifying the surface can ensure the performance requirements of the implant. Finally, this paper discusses the future development trend of the orthopedic implant.
