Integration of multiple superior features into a single flexible pressure sensor would result in devices with greater versatility and utility. To apply the device to variety scenarios solve problem accumulation e-waste environment, it is highly desirable combine degradability wide-range linearity characteristics device. Herein, we reported degradable multilayer fabric (DMF) consisting an ellipsoidal carbon nanotube (ECNT) polyvinylpyrrolidone/cellulose acetate electrospun fibers (PEF). The alternative layer-by-layer stacking ECNT PEF notably accelerates sensitivity toward pressure. optimized demonstrated 3.38 kPa-1 over wide measurement range from 0.1 500 kPa, as well great mechanical stability 2000 cycles. A good degradation performance was confirmed by both Fourier transform infrared (FTIR) characterization decomposition experiments sodium hydroxide solution. fabricated capable precepting physiological including subtle arterial pulse, dancing training, walking postures, accidental falls.

Abstract Flexible electromechanical sensors frequently suffer from unexpected impact loadings caused by slipping, collisions and falling objects, to name a few. Without sufficient protection, these undesired impacts would lead critical mechanical instability even damage flexible sensors, resulting in restricted measurement range imprecise sensing. Thus, it is of significance, but still fresh challenge enhance the stability energy‐absorption capacity under impacts. Here, multi‐design strategy proposed construct an interpenetrating‐phase cellulose‐acetate composite (IPC 2 ) architecture for impact‐intensive sensing applications. The external structure mimics bellows‐morphology beverage‐straws that deform programmed loading direction stability, while internal conductive core has co‐continuous can efficiently absorb energy. Systematic numerical analysis experimental tests demonstrate IPC presents excellent structural cyclic performance unique combination exceptional specific energy absorption (SEA = 2.66±1.2 kJ kg −1 ), low density ( ρ 720±10 m −3 properties (GF≈39.6). Remarkably, recovery behaviors terms shape electrical signals show good repeatability reliability. This study offers new framework exploit potentialities with protective functions commercial values.

Eutectogels are recently emerged as promising alternatives to hydrogels owing their good environmental stability derived from deep eutectic solvents (DES). However, construction of competent eutectogels with both high conductivity and mechanical toughness is still difficult achieve yet highly demanded. In this work, new LMNP-PEDOT-CMC-AA (LPCA) prepared using acrylic acid (AA) carboxymethylcellulose sodium (CMC) polymeric networks, liquid metal nanoparticle-poly(3,4-ethylenedioxythiophene) (LMNP-PEDOT) added multifunctional soft fillers. Benefiting the compliant conductive LMNP-PEDOT, LPCA exhibit (0.224 S m-1), electromechanical coupling, stretchability (4228%) exceptional (7.278 MJ m-3). Additionally, abundant hydrogen interactions available functional groups within endow them excellent self-healing adhesion on different substrates. Moreover, demonstrate superior tolerance including anti-freezing anti-drying, thus allowing for long-term reliability. These appealing characteristics enable accurate stable tracking human motions, well information delivery based Morse code. This study opens possibility designing tough enabled by LM composites.
