As a major component of the human body, the extracellular matrix (ECM) is a complex
biopolymer network. The ECM not only hosts a plethora of biochemical interactions but also …

Ionic tactile sensors (ITS) represent a new class of deformable sensory platforms that mimic
not only the tactile functions and topological structures but also the mechanotransduction …

Hydrogels have been developed since the 1960s for applications in personal care,
medicine, and engineering. Evidence has accumulated that hydrogels under prolonged …

The structure–property paradox of biological tissues, in which water-rich porous structures
efficiently transfer mass while remaining highly mechanically stiff, remains unsolved …

A real polymer network is never perfect, but the quantification of network imperfection has
been elusive. Here we quantify the network imperfection of a polyacrylamide hydrogel …

Tough hydrogels of many chemical compositions have been developed in recent years, but
their fatigue fracture has not been studied. The lack of study hinders further development of …

Hydrogels are materials widely used in countless applications, particularly in the biomedical,
pharmaceutical, and nutraceutical fields, because of their biocompatibility and their …

The fracture mechanics of hydrogels, especially those with significantly enhanced
toughness, has attracted extensive research interests. In this article we discuss the …

Following early research efforts devoted to achieving excellent sensitivity of electronic skins,
recent design schemes for these devices have focused on strategies for transduction of …

An ultrasensitive, visco‐poroelastic artificial mechanotransducer skin over a wide spectrum
of pressure is effectively demonstrated by directly mimicking the physiological tactile sensing …
