Summary: Stretchable microsupercapacitors have become important energy storage devices for next-generation deformable electronics. This study presents an ultrastretchable microsupercapacitor using two-dimensional (2D) transition metal carbides (MXenes) as electrode materials. The microsupercapacitor exhibits high specific capacitance, ultrahigh stretchability, and good retention of capacitance after repeated stretching. It also shows robust mechanical properties and stable charging-discharging capability under dynamic stretching. These developments offer a generic design strategy to enhance the deformability of microsupercapacitors based on 2D nanomaterials.

Summary: In this study, a facile and scalable patterning method for liquid metal conductors on an elastomer substrate is reported. Laser-activated patterns are used as versatile templates to define arbitrary liquid metal patterns. The as-prepared liquid metal features show excellent conductivity, high resolution, ultrahigh stretchability, and electromechanical durability. The practical suitability of liquid metal conductors is demonstrated by fabricating a stretchable LED matrix and a smart sensing glove. The maskless fabrication technique introduced here allows versatile patterning of liquid metal conductors with affordable costs, which may stimulate a broad range of applications in stretchable electronic devices and systems.

Summary: The yield-stress fluid introduced in this study is a printable, ultrastretchable, and transparent conductor that can transition between solid and liquid states by dispersing silica nanoparticles into a concentrated aqueous electrolyte. With solid-state appearances and the ability to transform into a liquid-like behavior upon tensile deformations, it offers high stretchability up to the fracture strain of the elastomer. Successful integrations of yield-stress fluid electrodes in highly stretchable strain sensors and light-emitting devices demonstrate its practical suitability for stretchable electronic devices and systems.

Summary: In this study, the authors demonstrate how the fast reaction rate activates charge redistribution in manganese hexacyanomanganates, which helps alleviate the strong Jahn-Teller effect of high-spin Mn(III) by solving the unequal number of electrons in e(g) orbitals. As a result, the dissolution of Mn is effectively suppressed, leading to improved long-term cyclability in an aqueous electrolyte.

Summary: In this study, ultrasoft and ultrastretchable wearable strain sensors are developed using liquid metal fillers in an elastic polymer. The sensors exhibit changes in effective resistance upon strains and can be used for monitoring body motions. The liquid metal dispersed elastomers possess ultra-stretchable and ultrasoft mechanical properties, making them ideal for wearable applications. Moreover, the anisotropic conductivity of the liquid metal elastomer film allows for manipulation of the locomotion of a robot.

Summary: This article demonstrates a high-resolution patternable, stretchable, and transparent conducting polymer by decoupling the engineering of material properties. The high conductivity is achieved through the rational design of an ionic additive, while the high stretchability is achieved by matching the mechanical properties to the substrate. The developed conducting polymer is patterned with a resolution less than 10 μm using nanosecond UV laser ablation, enabling the application of stretchable and transparent sensor arrays.
