Implantable transient electronic devices are almost constructed from biodegradable materials. These electronic devices can be degraded and absorbed in vivo, not only without the need for secondary surgery, but also avoid the negative effects of long-term implantation. As an emerging research field, it has enormous potential in vivo sensing and therapy. However, most implantable transient electronics require an external power supply to maintain normal operation, which greatly limits their applications in vivo. Therefore, a new type of biodegradable energy device with biocompatibility, controllability and biodegradability has become an urgent need in the field of medical engineering. This paper mainly introduce four biodegradable energy devices (biodegradable primary batteries, photovoltaic cells, supercapacitors and triboelectric nanogenerators) and their applications. In addition, the challenges and future trends that they have been faced are also discussed.
