In Situ Grown Silver–Polymer Framework with Coordination Complexes for Functional Artificial Tissues

Advanced Materials, Год журнала: 2023, Номер 35(24)

Опубликована: Апрель 29, 2023

Self-sensing actuators are critical to artificial robots with biomimetic proprio-/exteroception properties of biological neuromuscular systems. Existing add-on approaches, which physically blend heterogeneous sensor/actuator components, fall short yielding satisfactory solutions, considering their suboptimal interfaces, poor adhesion, and electronic/mechanical property mismatches. Here, a single homogeneous material platform is reported by creating silver-polymer framework (SPF), thus realizing the seamless sensing-actuation unification. The SPF-enabled elastomer highly stretchable (1200%), conductive (0.076 S m-1 ), strong (0.76 MPa in-strength), where polymer matrix synthesis in situ silver nanoparticles reduction accomplished simultaneously. Benefiting from multimodal sensing capability its architecture itself (mechanical thermal cues), self-sensing actuation (proprio-deformations external stimuli perceptions) achieved for SPF-based pneumatic actuator, alongside an excellent load-lifting attribute (up 3700 times own weight), substantiating advantage unified feature homogenous material. In view human somatosensitive muscular systems imitative functionality, SPF bodes well use next-generation functional tissues, including skins, human-machine robots, otherwise dynamic materials.

Abstract Flexible, breathable, and highly sensitive pressure sensors have increasingly become a focal point of interest due to their pivotal role in healthcare monitoring, advanced electronic skin applications, disease diagnosis. However, traditional methods, involving elastomer film‐based substrates or encapsulation techniques, often fall short mechanical mismatches, discomfort, lack breathability, limitations sensing abilities. Consequently, there is pressing need, yet it remains significant challenge create that are not only flexible, comfortable but also sensitive, durable, biocompatible. Herein, we present biocompatible breathable fabric‐based sensor, using nonwoven fabrics as both the electrode (coated with MXene/poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate [PEDOT:PSS]) interdigitated (printed MXene pattern) via scalable spray‐coating screen‐coating technique. The resultant device exhibits commendable air permeability, biocompatibility, performance, including remarkable sensitivity (754.5 kPa −1 ), rapid response/recovery time (180/110 ms), robust cycling stability. Furthermore, integration PEDOT:PSS plays crucial protecting nanosheets from oxidation, significantly enhancing device's long‐term durability. These outstanding features make this sensor suitable for applications full‐range human activities detection Our study underscores promising future flexible realm intelligent wearable electronics, setting new benchmark industry.
