Summary: This paper proposes a conceptual self-powered temperature monitoring platform for simultaneous real-time tracking of the temperature variation in the lower limb of a pregnant woman and her surrounding environment. The single yarn-based temperature (SYBT) sensor exhibits ultrahigh sensitivity, bending resistance, biocompatibility, and integrability with fabrics. The triboelectric nanogenerator embedded into a shoe provides energy for the self-powered features of the platform, and the temperatures are continuously monitored wirelessly with user interfaces.

Summary: Recent advancements in smart, wearable technologies have led to the ability to detect various medical conditions, including pathologic cardiac rhythms, through continuous collection and real-time analysis of electrocardiogram (ECG) data. This study presents a modified QRS detection algorithm, AMPT, which is a simplified version of the well-established Pan-Tompkins algorithm. Using archived ECG data, the AMPT algorithm demonstrated improved computational efficiency by 5-20x compared to the Pan-Tompkins algorithm, while also universally enhancing correctness. These findings support the translation of the AMPT algorithm to mobile platforms for continuous, real-time QRS detection.

Summary: This study aimed to quantitatively evaluate the effects of air purifiers on the spread of COVID-19 and suggested guidelines for their safe use. The results showed that while the air purifiers had little impact on the spread of simulated respiratory droplet nuclei, they significantly affected the spread of nano-sized virus aggregates. The constant operation of air purifiers with HEPA filters reduced the concentration of both simulated respiratory droplet nuclei and nano-sized aggregates, indicating their effectiveness in reducing airborne particles.
