摘要
植入式医疗电子器件对于人体健康监测及治疗至关重要,其正常运转需要外界电池供能,而电池电能耗尽后需要二次手术更换,该过程会对病人身心造成二次伤害并带来沉重的经济负担。人体运动的机械能和体内的化学能,如心跳、呼吸、血液循环和葡萄糖的氧化还原等,都具有转化为电能的潜力。近年来,自驱动能源收集技术的不断发展使得体内能量被有效收集后,可为植入式医疗电子器件供能。自驱动植入式能源收集器件主要包括压电纳米发电机、摩擦纳米发电机、光伏电池、热释电发电机、自驱动腕表、生物燃料电池和耳蜗内电位收集器等。该文讨论了植入式能源收集器件的种类、代表性应用及现存的挑战,并对其未来的应用进行了展望。
Implanted medical electronics(IMEs)is essential for healthcare and treatment.Battery is usually applied in the sustainable operation of IMEs.However,once these batteries finished their mission,the patients had to undergo a second operation to remove them and bear considerable financial burdens as well as severe pain.The human body abounds with mechanical and chemical energy,such as the heartbeat,breathing,blood circulation,and the oxidation-reduction of glucose.With the development of self-powered energy harvesting technology,the collected energy could be applied in powering IMEs.In this context,self-powered implantable energy harvesters(IEHs)based on the piezoelectric effect,triboelectric effect,photoelectric effect,pyroelectric effect,automatic wristwatch devices,biofuel cells and endocochlear potential were prepared.Here,this review article focuses on the classification and typical applications of self-powered IEHs.Furthermore,the current challenges and perspectives are also discussed.
