“…50 Comparable solidication and melting phase change behavior were also observed for Galinstan where Galinstan-PDMS composites remain so and exible at lower temperatures (below À20 C) compared to bulk Galinstan. 51 The supercooling effect was initially observed for pure Ga and Gabased nanoparticles and elucidated by the coexistence of liquid and solid phase. 14,52,53 The supercooling effect limits the application of LM nanodroplets in composites with stiffness tuning capability as solid-liquid phase transition occurs at extremely low temperature.…”

“…In an additional work, Koh et al explored the melting and solidification behavior of the room‐temperature liquid metal alloy gallium, indium, and tin (galinstan) when used in an elastomeric matrix for soft and stretchable electronic applications. This was done in order to determine the usable temperature range for such composites.…”

With haptic and pressure sensor manufacturing in the US totaling $US 1.6 billion in annual revenue—with 2% annual projected growth from 2018 to 2023—and tactical and service clothing manufacturing in the US totaling $US 242.9 million in annual revenue, the potential of advanced wearables continues to grow. As many fields tend toward miniaturized technologies in the modern age, many recent developments have been made for wearable platforms. Within the broad area of wearable platforms, there are many specific applications to consider, such as motion sensing, biomarker detection, monitoring of environmental pollutants, haptic sensors, enhanced soft robotics, and improving the safeguarding capabilities of armor. For these applications, the interfacial phenomena occurring between the continuous and discrete phases within the composite material are responsible for the device's response and bulk properties. Understanding these phenomena at the composite interfaces of the system allows for finer tuning of morphological, electromechanical, and other bulk properties, as well as the optimization of the wearable's output—in terms of the applications targeted. Control over these advanced composite materials is paramount in personalized health‐care systems, advanced defense technologies, commercial wearables. Recent advances on composite interfaces for wearable platforms are discussed, along with trends and an outlook of the field.

“…Galinstan freezes at −19 °C and EGaIn has a melting point of 15.5 °C, meaning that below this temperature the metals will no longer act as a liquid. [ 23,24 ] Additionally, galinstan has a density of 6.44 g cm −3 while EGaIn has a density of 6.25 g cm −3 . [ 23 ] Oftentimes, gallium‐based liquid metals are dispersed into lower density solvents, leading to settling of the liquid metal droplets within the dispersed solution.…”

Deformable electronics, specifically those incorporating liquid metal, allow for previously inaccessible mechanical behavior and exciting new technologies. This is demonstrated by recent, promising advances in the fabrication, characterization, device performance, and applications of liquid metal electronics. Through the use of liquid metals and soft, stretchable materials, it is shown that devices that provide stretchability and improved safety and comfort between humans and machines can achieve comparable or better electrical performance than conventional alternatives. Many of the latest major advances in liquid metal electronics focus on fundamental, deformable, passive circuit components and materials including capacitors, inductors, resistors, electrodes, wires, and composite materials, such as advances in biomimicry and deformation‐based sensing using both capacitors and inductors. Liquid metal passive components and materials have led to further progress in deformable secondary devices and applications such as antennas, actuators, power sources, and thermal management devices, including mechanical tuning for antennas, self‐sensing actuators, and power sources operational under stress. While deformable liquid metal electronics are still faced with challenges, the continued expansion of the field of liquid metal circuits is dramatically altering the research landscape of reconfigurable, self‐healable, and magnetically controllable electronics and revolutionalizing the way that electronics will be used in the future.
