Summary: This study demonstrates the development of wearable supercapacitors with repeated shape editability, excellent self-healing capability, and long-term cycling durability by sandwiching hydrogel electrolytes between two electrodes. The use of hydrogel electrolytes with unique cross-linking structures enhances the long-term cycling durability, while the dynamic crosslinking sites stabilize the supercapacitors during charge-discharge processes. The fabricated supercapacitors show high capacitance retention rates and can be repeatedly processed into various shapes without losing capacitance.

Summary: This paper presents a nanocomposite approach for creating stretchable strain sensors using graphene/PEDOT:PSS and MnO2 NWs. The response of the sensor to different concentrations of MnO2 NWs was experimentally analyzed. The results showed that the sensor exhibited a highly linear response over a wide strain range, with a low level of hysteresis and a short response time. The proposed sensor demonstrated high stability and repeatability over numerous stretch and relax cycles, making it suitable for human motion detection in scenarios involving large deformation.

Summary: This study introduces a new type of intrinsically stretchable, printable electroactive ink made of 1T-MoS2 and a fluoroelastomer (FE). The ink is created by fluorinating metallic-phase MoS2 nanosheets with FE under high-power ultra-sonication, resulting in a material that is inherently stretchable and suitable for stretchable electronic devices. The printed material shows good specific capacitance and energy density, making it a promising platform for in-plane fabrication of stretchable micro-supercapacitor devices for wearable electronic applications.

Summary: In this study, Na ion pre-intercalated delta-MnO2 immobilized on flexible carbon cloth (CC) was fabricated for symmetric supercapacitors. The results showed that NaxMnO2-32-N with NH4+ additive exhibited higher capacitance and better rate capability. The increase of specific surface area, Na+ ion pre-embedded content, and deposition mass were found to be the dominant factors in optimizing the electrochemical properties of delta-MnO2. The assembled flexible supercapacitor demonstrated high energy density, power density, capacity retention rate, and coulomb efficiency.
