A Self-Healable, Ion-Dipole Bond-Triggered Mechanosensitive Skin for Iontronic Wearable Sensors |
| 초록 |
The self-healing properties and ionic sensing system of the mammalian skin have inspired the design of various iontronic based self-healing mechanosensors that respond to strain, torsion and pressure. For effective sensing mechanism, inorganic nanoparticles have been introduced into ionic materials for ion-confinement effect to control ion kinetics for efficient sensitivity. However, the design of these heterogeneous systems is complex and incorporating self-healing property to increase device lifespan is nearly impossible. Herein, we report a novel homogenous system based on Cl functionalized polyurethane (PU) for ion-confinement effect together with fast self-healing capabilities at room temperature. The ions in the system are confined to the Cl functional groups through ion-dipole interaction, generating low initial capacitance but very high final capacitance as more ions are released under deformation for excellent sensitivity. Moreover, the PU consists of high chain mobility IPDI for fast self-healing (91% efficiency at 60 min) and also due to the intrinsic rigid property of the Cl functional groups, the system possesses superb elastic recovery (100%) under deformation |
