“…The surface roughness partially prevents the creation of good contact [15,16], and as a result, adhesion often does not manifest itself. However, adhesion should be taken into account when developing certain types of microelectronic devices, where the size of contacting objects is small, and adhesive forces between them are significant [17,18]. This is especially critical, for example, for MEMS (micro electric mechanical Computation 2024, 12, 107 2 of 17 systems), where contacting surfaces can spontaneously stick to each other due to adhesion [19,20].…”

This work continues the study of the process of friction between a steel spherical indenter and a soft elastic elastomer previously published in our paper. It is done in the context of our previous experimental results obtained on systems with strongly pronounced adhesive interaction between the surfaces of contacting bodies during the process of friction between a steel spherical indenter and a soft elastic elastomer. In the present paper, we concentrate on the theoretical study of the processes developing in a vertical cross-section of the system. For continuity, here the case of indenter motion at a low speed at different indentation depths is considered as before. The analysis of the evolution of normal and tangential contact forces, mean normal pressure, tangential stresses, as well as the size of the contact area is performed. Despite its relative simplicity, a numerical two-dimensional (2D = 1 + 1) model, which is used here, satisfactorily reproduces experimentally observed effects. Furthermore, it allows direct visualization of the motion in the vertical cross-section of the system, which is currently invisible experimentally. Partially, it recalls two-dimensional (2D = 1 + 1) models recently proposed to describe the “turbulent” shear flow of solids under torsion and in cellular materials. The observations extracted from the model help us to understand better the adhesive processes that underlie the experimental results.

Switchable adhesion, a phenomenon characterized by the ability to transition between attachment and detachment states under external stimuli, has recently gained popularity in various advanced devices. The realization of the desired functionalities on such surfaces relies on intricate interfacial designs. A general understanding of the commonalities and distinctions among these designs can foster the development of refined switchable adhesion interfaces (SAIs). To address this, this review first examines adhesion interfaces by focusing on the fundamental interactions at the atomic/molecular level, adhesion models, and their correlation with the diverse forces/bonds that dominate the adhesion behaviors. The latest progress in SAIs based on various forces/bonds, including electrostatic force, van der Waals force, capillary force, chemical bond, and suction force, is then discussed with regard to their specific design strategies, such as structures, components, and triggers. Additionally, an extensive overview of the broad applications of SAIs in fields ranging from space to biomedicine is provided, along with an exploration of the prevailing challenges and potential opportunities. With the rapid progress that has been made in state‐of‐the‐art mechanisms and design strategies, SAIs are expected to undergo booming development in the foreseeable future.

Achieving safe robotic manipulation at the microscopic scale usually requires sophisticated equipment, imposing accessibility difficulty in practice. Inspired by tiny bubbles in nature, a new paradigm is proposed for achieving multifunctional manipulation and sensing using microbubbles for biological application in aqueous environments at low cost. Without demanding the expensive cost of fabrication devices, bubbles with various sizes are easy to generate in situ, which is enabled by bubble‐endowed interface interactions. It is demonstrated that bubbles acting as micro end‐effectors rapidly and adaptively realize dexterous manipulation of microobjects such as biological organisms and droplets. They can function as microgrippers to grasp microobjects based on interface interaction‐induced adhesion and act as soft micromanipulators to safely manipulate fragile objects. Moreover, the bubble micro end‐effector can sense and perceive the designated objects for contact measurement of microforces or surface textures at a microscopic scale via the shape changes of their ultrasoft structures. The reported method successfully integrates grasping, manipulation, and measurement functions in liquid using a single microbubble of less than 1 mm3 volume. These nondestructive functionalities showcase promising prospects for bubble‐based micro end‐effectors in biological manipulation and sensing applications.
