摘要
植入式瞬态电子器件由可降解材料构建而成,这些电子器件能够在体内降解并吸收,无需二次手术取出,避免了长期植入产生的负面效应。作为一个新兴的研究领域,植入式瞬态电子器件在体内传感和治疗方面都有着巨大的潜能。然而,大多数植入式瞬态电子器件的正常工作都需要外部能源供给,这极大限制了它们在体内的应用。因此,一种具有生物相容性、可控降解和生物可吸收的新式生物可降解能源器件,成为了植入式瞬态电子器件的迫切需求。介绍了4种生物可降解能源器件(生物可降解原电池、光伏电池、超级电容器和摩擦纳米发电机)及其应用,并探讨了各自所面临的挑战和未来发展趋势。
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.
