Materials and Biomedical Applications of Implantable Electronic Devices

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.
