A protein-coated micro-sucker patch inspired by octopus for adhesion in wet conditions

Abstract In medical robotics, micromanipulation becomes particularly challenging in the presence of blood and secretions. Nature offers many examples of adhesion strategies, which can be divided into two macro-categories: morphological adjustments and chemical adaptations. This paper analyzes how tw...
