摘　　要：传统工艺制得的摩擦纳米发电机(Triboelectric Nanogenerators,TENGs)形状单一,难以满足实际应用中复杂多变的形状要求。且多数报道的TENGS主要由不可降解材料制成,限制了其在生物医用领域的进一步应用。针对上述问题,采用3D打印技术实现对微米纤维的个性化排列,以具有良好生物相容性的可降解生物医用弹性体聚癸二酸甘油酯(poly(glycerol Sebacate),PGS)为基材,制备了一体式纤维基PEDOT:PSS@PGS摩擦纳米发电机。其具有优良的弹性、耐疲劳性、良好稳定的电输出性。同时,PGS基的TENG在脂肪酶溶液中1小时的降解率可达(98.3±1.3)%,呈现出良好的生物降解性。本文展示了该TENG在运动监测方面的应用,未来有望用于疾病监测和电疗等领域。The Triboelectric Nanogenerators(TENGs)produced by traditional technology have a single shape,making it difficult to meet the complex and variable shape requirements in practical applications.Most of the reported TENGs are mainly composed of non-degradable materials,which limits their further application in the biomedical field.To address these issues,3D printing technology was employed to achieve the personalized arrangement of micrometer fibers,and integrated PEDOT:PSS@PGS triboelectric nanogenerators were fabricated using poly(glycerol sebacate)(PGS),a biodegradable biomedical elastomer with good biocompatibility,as the substrate.It exhibited stable electrical output,as well as excellent elasticity and fatigue resistance.Meanwhile,the PCGS-based TENG demonstrated good biodegradability with a degradation rate of up to(98.3±1.3%)in lipase for 1 hour.This paper showcases the application of this TENG in motion monitoring and is expected to be utilized in the fields of disease monitoring and electrotherapy in the future.
