In “Aligned PLLA electrospun fibres based biodegradable triboelectric nanogenerator,” the authors present a new construction method for potential components in energy harvesters. These energy harvesters—like solar cells—”are not always developed using sustainable materials.” Creating components that are biodegradable could make these devices more environmentally friendly. “The presented approach,” the authors argue, “can provide attractive green energy harvesting machine to power portable devices at a large scale—without having to worry about the end-of-life electronic waste management.”
