Biomimetic flexible electronics for E-skin have received increasing attention, due to their ability sense various movements. However, the development of smart skin-mimic material remains a challenge. Here, simple and effective approach is reported fabricate super-tough, stretchable, self-healing conductive hydrogel consisting polyvinyl alcohol (PVA), Ti3 C2 Tx MXene nanosheets, polypyrrole (PPy) (PMP hydrogel). The nanosheets Fe3+ serve as multifunctional cross-linkers stress transfer centers, facilitate considerable high conductivity, super toughness, ultra-high stretchability (elongation up 4300%) PMP with. hydrogels also exhibit rapid repeatable self-adhesive capacity because presence dynamic borate ester bond. capacitive strain sensor made by shows relatively broad range sensing (up 400%), with feature. can precisely monitor human physiological signals, including joint movements, facial expressions, pulse waves. hydrogel-based supercapacitor demonstrated capacitance retention ≈92.83% coulombic efficiency ≈100%.

Flexible capacitive tactile sensors show great promise in personalized healthcare monitoring and human–machine interfaces, but their practical application is normally hindered because they rarely possess the required comprehensive performance, that is, high pressure sensitivity fast response within a broad range, structure robustness, performance consistency, etc. This paper aims to engineer flexible with highly ordered porous dielectric microstructures 3D-printing-based fully solution-processable fabrication process. The proposed layer uniformly distributed interior microporous can not only increase its compressibility dynamic an extended range also enlarge contact area electrodes, contributing simultaneous improvement sensitivity, speed, detection robustness. Meanwhile, owing superior abilities complex manufacturing dimension controlling, process enables consistent of microstructure thus guarantees device consistency. As result, prepared exhibit 0.21 kPa–1, relaxation times 112 152 ms, interface bonding strength more than 455.2 kPa, excellent consistency (≤5.47% deviation among different batches sensors) tunability. Encouraged by this, sensor further integrated wireless readout circuit realizes wearable various biosignals (pulse waves heart rate) body movements (from slight finger touch large knee bending). Finally, influence law feature parameters on established finite element method, paving way for optimization. study motivates development toward application.
