Summary: A coaxial wet-spinning process was used to fabricate intrinsically stretchable, highly conductive, and conductance-stable liquid metal sheath-core microfibers, which can be stretched up to 1170% and maintain high conductivity with minimal resistance change. These microfibers can be woven into everyday gloves or fabrics, serving as efficient joule heaters, electrothermochromic displays, and self-powered wearable sensors for monitoring human activities.

Summary: Model-based compensators are proposed for force sensors with soft materials to eliminate the negative effects of viscoelasticity. The first-order Volterra gray box model accurately characterizes high-order linear viscoelasticity, avoiding the need for high-order parameters and complex calculations. Experimental results on a soft-material-based capacitive force sensor demonstrate improved compensation performance and reduced calculation time compared to existing methods.

Summary: The out-of-autoclave processes of carbon fiber thermoplastic composites are gaining attention due to their potential for reducing economic costs. This study proposes a method for measuring the viscosity of carbon fiber/polyetherketoneketone composites using squeeze flow experiments in a rheometer. The flow behavior is characterized using a modified Stefan's law assuming a power law fluid behavior with full anisotropy, and the values of the power law parameters K and n are obtained. Furthermore, the study shows that the squeeze flow behavior is different from dynamic measurements, invalidating the Cox-Merz rule for these materials.

Summary: The silver nanoparticle sensor fabricated using an aerodynamically focused nanomaterial (AFN) printing system showed high performance with a maximum measurable frequency and gauge factor. The sensor allowed independent measurement of strain and vibration, and real-time measurement using a Kalman filter-based signal separation algorithm. Moreover, the sensor was applied to quadrotor condition monitoring for motion prediction.

Summary: This study investigates the flexural performance of hybrid reinforced concrete beams with steel and basalt fiber-reinforced polymer bars. The results demonstrate that adding BFRP bars on the tension side can significantly improve the structural performance of the beam. Furthermore, the flexural capacity and post-yielding stiffness of the HRC beams are governed by the bond characteristics of the FRP bars used.

Summary: This paper presents a new approach to investigate the bond deterioration of corroded steel bars embedded in reinforced concrete (RC) beams. The study utilizes a nonlinear finite element model to simulate an experimental database of existing corroded RC beams, divided into accelerated and long-term corroded beams. The results demonstrate the need for different simulation methods based on the corrosion condition, and propose a novel bond-slip model which shows excellent accuracy in predicting the bond deterioration due to corrosion in RC beams.
