如今，随着物联网的发展，智能家居因其提高人类生活质量的能力而受到广泛关注。作为智能家居的重要组成部分，具有环保性、出色稳定性和输出性能的电子设备显得尤为重要。摩擦电纳米发电机（TENG）可以将低频机械能转化为电输出信号。低生产成本、高能量转换效率和出色的稳定性使其更具吸引力然而，传统的摩擦层材料普遍存在生物相容性差、毒性高和难以生物降解等问题。
木质纤维作为世界上储量最丰富的聚合物材料，由于具有优异的力学性能、高反应活性和生物相容性等特点而受到研究者的广泛关注。但以木质纤维制备的摩擦层普遍存在电输出信号弱、开路电压和功率密度较低等问题，使得以木质纤维制备的摩擦层材料难以被广泛应用。针对上述问题，研究人员利用简单的木质素脱除手段，构建了可降解的全木质纤维基的TENG，探讨了木质纤维空间结构和TENG输出信号间的关系。以此制备的全木质TENG展现出良好的电输出信号（580 kV m-2、167 mA m-2），并探讨了输出信号与施加压力、环境湿度的关系。此外，研究人员将其制备得到传感阵列，初步展示了其在智能家居中的应用。
