Abstract in another language

This study investigates the relationship between the electrical output produced by triboelectric nanogenerators (TENGs) due to contact electrification and the effective contact area during sliding motion. Polymer foils were tested against aluminium in controlled process and environmental conditions. The results show a clear trend between increasing transferred charge and an estimated larger contact area. Time-resolved measurements suggest that changes in contact conditions (e.g. due to flattening or wear) play a key role in electrical output.
