With the continuous advancement of internet of things, big data, and artificial intelligence technologies, self-powered functionalized applications have emerged as pivotal components in the realm of smart technology. Here, we present a flexible and environmentally sustainable wood-based triboelectric nanogenerator (W-TENG) that enables the self-powered functionalization of applications in the emerging smart field. By employing a straightforward yet effective approach utilizing natural balsa wood, the W-TENG exhibits remarkable flexibility, stability, and sensitivity. Notably, balsa wood possesses a lower weight, density, and crystallinity compared to other types of natural wood, resulting in thinner internal cell walls, larger individual cells and a more porous structure. These characteristics prove particularly advantageous for solvent modification. Given the prevalent use of wood materials in domestic construction, the energy-efficient W-TENG can be seamlessly integrated into various smart applications, including wireless switches, home flooring, and energy-saving lamps. Moreover, this integration offers several benefits such as cost-effectiveness, high durability, ease of processing, and environmental friendliness. This research not only expands the range of self-powered applications in the smart sector but also drives the development of eco-friendly W-TENG electronics.

灵活的木质摩擦纳米发电机，用于多功能自供电传感


随着物联网、大数据、人工智能技术的不断进步，自驱动的功能化应用已成为智能技术领域的关键组成部分。在这里，我们提出了一种灵活且环境可持续的木质摩擦纳米发电机（W-TENG），它能够实现新兴智能领域应用的自供电功能化。通过采用简单而有效的方法利用天然轻木，W-TENG 表现出卓越的灵活性、稳定性和灵敏度。值得注意的是，与其他类型的天然木材相比，轻木具有较低的重量、密度和结晶度，从而导致内部细胞壁更薄、单个细胞更大和多孔结构更多。这些特性被证明对于溶剂改性特别有利。鉴于国内建筑普遍使用木质材料，节能的W-TENG可以无缝集成到各种智能应用中，包括无线开关、家庭地板和节能灯。此外，这种集成还具有多种优势，例如成本效益、高耐用性、易于加工和环境友好。这项研究不仅扩大了智能领域自供电应用的范围，而且推动了环保型W-TENG电子产品的发展。
