Significance The present work introduces an on-demand cleaning technology that addresses the problem of crystal encrustation and bacterial biofilm formation, with potential applications across various medical devices. Cleaning action is achieved by combining surface topographies and ultrasound-induced fluid motion, creating a robust solution to keep surfaces free from biofilm and encrustation. This approach is particularly important in indwelling medical devices, where maintaining clean surfaces is critical to patient safety and device performance. By effectively addressing these issues, our technology has the potential to enhance equipment efficiency and longevity, reduce contamination risks, and lower operational costs, ultimately leading to improvements in public health outcomes.
