Опубликована: Янв. 16, 2025

Highly sensitive strain sensors are crucial for monitoring subtle plant growth changes and show diverse applications in sensing. However, the prevailing integrated fabrication methods such tend to be costly complex, impeding their fundamental design practical usage. Herein, we develop a simple effective multimaterial all-3D printing technique manufacture with multilayered structure. Such an all-3D-printed sensor exhibits excellent sensing performance enabling precise detection of minor strains growth, including high stretchability (> 300%), sensitivity (~12.78) good linearity (0.98), long-term stability over 3,000 loading/unloading cycles. We further validate potential our 3D-printed accurate continuous bamboo both horizontal vertical directions 14 days. Our offers promising avenue systems toward monitoring.

The wearable electronic technique is increasingly becoming an effective approach to overcoming the communication obstacles between signers and non-signers. However, efficacy of conducting hydrogels currently proposed as flexible sensor devices hindered by their poor processability matrix mismatch, which frequently results in adhesion failure at combined interfaces deterioration mechanical electrochemical performance. Herein, we propose a hydrogel composed rigid hydrophobic aggregated polyaniline was homogeneously embedded, while quaternate-functionalized nucleobase moieties endowed network with adhesiveness. Accordingly, resulting chitosan-graft-polyaniline (chi-g-PANI) copolymers exhibited promising conductivity (4.8 S·m-1) because uniformly dispersed components high strain strength (0.84 MPa) chain entanglement chitosan after soaking. In addition, modified adenine molecules not only realized synchronization improving stretchability (up 1303%) exhibiting skin-like elastic modulus (≈184 kPa), but also provided durable interfacial contact various materials. further fabricated into strain-monitoring for information encryption sign language transmission based on its sensing stability sensitivity up 2.77. developed interpreting system provides innovative strategy assist auditory or speech-impaired people communicating non-signers using visual-gestural patterns including body movements facial expressions.
