Shape-Controlled Poly(N-isopropylacrylamide) Actuators Enabled by Tensile-Stress Mismatch for Temperature-Adaptive Textiles

Thermal comfort is a key determinant of human health and requires adaptive responses to dynamic environments. Here, we report a temperature-adaptive textile enabled by a tensile stress mismatch-driven poly(N-isopropylacrylamide) (PNIPAM) actuator operating within a human-friendly...

Wearable photovoltaic textiles: From device technologies to long‐term reliability

Abstract Photovoltaic (PV) textiles are emerging as a promising class of energy‐harvesting systems that combine solar conversion capability with the softness, porosity, and wearability of fabrics. Unlike conventional rigid modules, PV textiles are designed to conform to the human...

Residential indoor air monitoring to assess long-term exposure to air pollution in susceptible populations for epidemiology: overview and early findings

While there has been accumulating evidence of the association between long-term exposure to air pollution and various health endpoints, most epidemiological studies relied on ambient air pollution which showed substantial deviation from indoor. This difference could lead to biase...

Effect of Plasma Excitation Mode on Rutile TiO2 MIM Capacitors Grown on RuO2 Seed Electrodes

Maintaining low leakage current with high capacitance density in metal–insulator–metal (MIM) capacitors is essential for next-generation dynamic random-access memory (DRAM) scaling. Rutile TiO2 is a promising high-k dielectric; however, its narrow bandgap causes high leakage, whi...

Beyond Dissolved Oxygen: Integrated Assessment of Multistage Vortex Aeration Effects on Urban Reservoir Water Quality

Aeration is widely used to increase the oxygen concentration in urban reservoirs, but its broader effect on nutrients, organic matter, and integrated water quality status remains uncertain. This study evaluated the response of the Jangrim reservoir, Busan, South Korea, to a multi...

Analysing Korean children's speech data for early childhood educational services: age-specific insights from text and audio analysis

Abstract As speech-based artificial intelligence (AI) becomes integrated into educational contexts, attention is growing towards its role in supporting child-centred learning environments. This study offers insights for developing child-friendly conversational AI systems by analy...

Effect of visual stimulation on quantitative light-touch assessment using the active von Frey filament test

Quantitative assessment of light-touch sensation is essential in the evaluation of peripheral nerve disorders. Although the active von Frey filament test (AvF) provides objective and continuous tactile threshold measurements, the influence of testing conditions on AvF values rema...
