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.</p><p>Highlights:</p><p>1 An up-to-date review of the natural materials used for triboelectric energy harvesting is provided.<br>2 Major parameters of the electric output are identified and compared for different materials.<br>3 Best results (14 mW) were obtained for dry leaf powder in combination with poly(vinylidene fluoride) in contact-separation mode.</p> ER -
