Water-enabled electricity generation (WEG) technologies are considered to be an attractive and renewable approach to meet energy crisis and environmental pollution globally. However, the existing WEG technologies still face tremendous challenges including high material cost, harmful components, and specific environmental requirements. Herein, a high-performance wood-based moisture-enabled electric generator (WMEG) is fabricated. Natural wood is cut perpendicular to the tree growth direction and engineered by simple chemical modification. The obtained bilayer wood membrane has robust mechanical framework with aligned ion nanochannels, abundant dissociated functional groups, and spontaneous water adsorption in the air. At the relative humidity of 85%, one WMEG can generate a voltage of 0.57 V. The device can also effectively sense biological water information as a self-powered sensor. The biophile design contributes a practical moist-electric generation strategy that offers clean energy, especially for undeveloped and disaster-relief regions where electricity is limited by high cost or crippled power facilities.

具有对齐离子纳米通道的双层木膜用于自发湿发电

水力发电 (WEG) 技术被认为是应对全球能源危机和环境污染的一种有吸引力的可再生方法。然而，现有的 WEG 技术仍然面临着巨大的挑战，包括高昂的材料成本、有害成分和特定的环境要求。在这里，制造了一种高性能的木质防潮发电机（WMEG）。天然木材垂直于树木生长方向切割，并通过简单的化学改性进行工程改造。获得的双层木膜具有坚固的机械框架，具有对齐的离子纳米通道、丰富的解离官能团和空气中的自发吸水性。在 85% 的相对湿度下，一个 WMEG 可以产生 0.57 V 的电压。该设备还可以作为自供电传感器有效地感知生物水信息。亲生物设计有助于提供一种实用的湿发电策略，提供清洁能源，特别是对于电力受限于高成本或电力设施瘫痪的未开发和救灾地区。
