This work reports a flexible fiber sensor with a core–shell structure that combines high strain with high sensitivity prepared by a swelling diffusion method. The fiber sensor has been integrated into a glove to develop a wearable gesture speech recognition system with high sensitivity and accuracy. In addition, the pressure distribution on the curved...

Abstract The dynamic mechanical strength of the extracellular matrix (ECM) has been demonstrated to play important role in determining the cell behavior. Growing evidences suggest that the gradual stiffening process of the matrix is particularly decisive during tissue development and wound healing. Herein, we provide a novel strategy to prepare hydrogels...

Abstract The utilization of polymer conformations to construct a variety of superlattices is a common method within the field. However, this technique often results in only long-range ordering rather than the formation of distinct superlattices. In our study, we successfully obtained a well-organized array of discrete pancake-shaped superlattices (DPSs)...

Abstract The rapid growth of the Internet of Things and wearable sensors has led to advancements in monitoring technology in the field of health. One such advancement is the development of wearable respiratory sensors, which offer a new approach to real-time respiratory monitoring compared to traditional methods. However, the energy consumption of...

Rational design of europium (Eu)-, terbium (Tb)-, and dysprosium (Dy)-based single-chain nanoparticles (SCNPs)−with diameter below 10 nm−and their use as “visual” pass/fail sensors of maximum permissible concentration (m.p.c.) of Cu2+ ions in water. Abstract The maximum permissible concentration (m.p.c.) of Cu2+ ions in drinking water, as...

A thermal-responsive surface-enhanced Raman scattering (SERS) substrate is constructed by utilizing poly(ionic liquid)s (PILs) as joint parts to tether both gold nanoparticles (AuNPs) and analytes onto poly(N-isopropylacrylamide) (PNIPAm). The activity of the SERS substrate can be reversibly changed in response to the temperature stimuli, which means...
