This review highlights the unique techniques for patterning liquid metals containing gallium
(eg, eutectic gallium indium, EGaIn). These techniques are enabled by two unique attributes …

An elastic printed circuit board (E-PCB) is a conductive framework used for the facile
assembly of system-level stretchable electronics. E-PCBs require elastic conductors that …

Self-healing hydrogels use spontaneous intermolecular forces to recover from physical
damage caused by extreme strain, pressure or tearing. Such materials are of potential use in …

Hydrogels exhibit potential applications in smart wearable devices because of their
exceptional sensitivity to various external stimuli. However, their applications are limited by …

Skin electronics require stretchable conductors that satisfy metallike conductivity, high
stretchability, ultrathin thickness, and facile patternability, but achieving these characteristics …

Hydrogels offer tissue-like compliance, stretchability, fracture toughness, ionic conductivity
and compatibility with biological tissues. However, their electrical conductivity (< 100 S cm …

Abstract Eutectic gallium–indium (EGaIn), a liquid metal with a melting point close to or
below room temperature, has attracted extensive attention in recent years due to its …

In the era of Internet-of-things, many things can stay connected; however, biological
systems, including those necessary for human health, remain unable to stay connected to …

Soft robotics inspired by the movement of living organisms, with excellent adaptability and
