Triboelectric nanogenerators (TENGs) are promising electric energy harvesting devices as they can produce renewable clean energy using mechanical excitations from the environment. Several designs of triboelectric energy harvesters relying on biocompatible and eco-friendly natural materials have been introduced in recent years. Their ability to provide customizable self-powering for a wide range of applications, including biomedical devices, pressure and chemical sensors, and battery charging appliances, has been demonstrated. This review summarizes major advances already achieved in the field of triboelectric energy harvesting using biocompatible and eco-friendly natural materials. A rigorous, comparative, and critical analysis of preparation and testing methods is also presented. Electric power up to 14 mW was already achieved for the dry leaf/polyvinylidene fluoride-based TENG devices. These findings highlight the potential of eco-friendly self-powering systems and demonstrate the unique properties of the plants to generate electric energy for multiple applications.
摩擦纳米发电机（TENGs）是很有前景的电能收集装置，因为它们可以利用来自环境的机械激励产生可再生清洁能源。近年来，已经推出了几种依靠生物相容性和生态友好型天然材料的摩擦电能收集器设计。它们为包括生物医学设备、压力和化学传感器以及电池充电装置在内的广泛应用提供可定制自供电的能力已经得到证明。本综述总结了在使用生物相容性和生态友好型天然材料的摩擦电能收集领域已经取得的主要进展。还对制备和测试方法进行了严谨、比较性和批判性分析。基于干叶/聚偏二氟乙烯的TENG装置已经实现了高达14毫瓦的电功率。这些发现突出了生态友好型自供电系统的潜力，并展示了植物产生电能用于多种应用的独特特性。
