摘要：

The development of fabric-based triboelectric energy harvesters is of great interest for converting human motion into electricity and is relevant for the development of wearable electronics. However, such harvesters exhibit significant degradation in performance under high humidity conditions. To solve this problem, a humidity-resistant, fabric-based triboelectric energy harvester by depositing self-assembled monolayers (SAM) to increase the hydrophobicity of the fabric surface is demonstrated. The SAM coating is compatible with various fabrics and a noticeable improvement in triboelectric performance under high humidity conditions (relative humidity approximate to 85%) is observed, while the fabric maintains outstanding breathability. Moreover, the harvester exhibits no degradation in the output voltage over 5 x 10(4) cycles of loading/unloading, indicating excellent stability. The energy harvester is demonstrated as a wearable device by mounting it onto various parts of the human body and it is validated that the harvester successfully generates electrical power from human motion. Based on the humidity-resistant triboelectric performance and the ease and cost-effectiveness of the SAM coating, the harvester is expected to provide meaningful opportunities for the development of self-powered smart clothes or wearable healthcare devices.
