Bioinspired All-Fibrous Directional Moisture-Wicking Electronic Skins for Biomechanical Energy Harvesting and All-Range Health Sensing

Nano-Micro Letters, Год журнала: 2023, Номер 15(1)

Опубликована: Март 2, 2023

Electronic skins can monitor minute physiological signal variations in the human and represent body’s state, showing an emerging trend for alternative medical diagnostics human–machine interfaces. In this study, we designed a bioinspired directional moisture-wicking electronic skin (DMWES) based on construction of heterogeneous fibrous membranes conductive MXene/CNTs electrospraying layer. Unidirectional moisture transfer was successfully realized by surface energy gradient push–pull effect via design distinct hydrophobic-hydrophilic difference, which spontaneously absorb sweat from skin. The DMWES membrane showed excellent comprehensive pressure sensing performance, high sensitivity (maximum 548.09 kPa−1), wide linear range, rapid response recovery time. addition, single-electrode triboelectric nanogenerator deliver areal power density 21.6 µW m−2 good cycling stability harvesting. Moreover, superior performance enabled all-range healthcare sensing, including accurate pulse monitoring, voice recognition, gait recognition. This work will help to boost development next-generation breathable applications AI, interaction, soft robots.
