• without any extra power consumption. Based on efficient conversion of ambient mechanical energy into electricity, P-TENGs have been extensively utilized in self-powered mechanosensing devices [150] (e.g., pressure, tactile, strain, and force sensors). Some special but also frequently required applications

Results: We report here on the influence of substrate stiffness on the adhesion of the human pathogen Acanthamoebae castellanii (A. castellanii). By comparing the
