Summary: This study presents a method of spray coating liquid metal nanoparticle systems onto textiles to create flexible and robust electrodes. The resulting electrodes, known as TILEs, exhibit comparable sensing capabilities and skin-electrode impedance to commercial wet electrodes, while also providing improved wearability. The biocompatibility of TILEs in a skin environment is demonstrated, and they outperform previously reported textile-based dry electrodes in terms of sensing performance.

Summary: Textile stretchable electronics are favorable for various wearable applications due to their ability to conform to the curved human skin. However, the importance of mechanical stretchability has been overemphasized, while the essential electrical characteristics, such as conductivity and electrical stability, have been neglected. In this study, we present a stretchable textile interconnects called multi-layer helical yarn (MLHY), which exhibits both supreme stretching capability and ultrahigh conductivity with nearly 100% electrical stability. The MLHYs can be easily integrated into textile structures using sewing, weaving, or knitting technologies, making them reliable and promising stretchable interconnects for versatile textile stretchable electronics.

Summary: This paper proposes a portable ECG monitoring system for recording abdominal ECG of pregnant women, including both maternal ECG (MECG) and fetal ECG (FECG), which can be used for fetal heart rate (FHR) monitoring at home. The system utilizes an adaptive dual threshold and independent component analysis algorithm to extract FECG from the signals. Experimental results demonstrate that the system can accurately record FECG and heart rate information in different postures with good signal quality.

Summary: This study explores the use of statistical methods and various signal quality indices (SQIs) to optimize knitted textile electrodes for electrocardiogram (ECG) recordings. The best SQIs were achieved with dry electrodes made of conductive yarn, compact knit structure, and medium roughness. Sewing electrodes at their edges into the knitted garment outperformed other methods, reducing motion artifacts and allowing for independent movement of the garment. Tests on a healthy volunteer showed excellent system performance during gentle ambulation. The advantage of using SQIs in optimizing dry textile ECG electrodes is the availability of a quantitative benchmark for comparison.

Summary: This study investigates the efficacy and feasibility of dry-contact electrode materials employed in smart textiles for electromyography (EMG) recordings. Results show that most materials have a strong positive correlation with gel electrodes in terms of mean power spectral density (PSD), and the inclusion of ionic liquids or the use of raised or flat electrodes does not significantly affect signal quality. Durability and long-term stability of the electrodes are recommended to be studied in future research.

Summary: Researchers have developed a mechanical approach using magnetic carbon nanotubes to treat chemoresistant glioblastoma (GBM). GBM cells can internalize the nanotubes and their mobilization by rotating magnetic fields leads to cell death. In vivo studies show that spatiotemporally controlled release of the nanotubes inhibits GBM growth. Functionalizing the nanotubes with an antibody that recognizes GBM cell surface antigen CD44 enhances their recognition of cancer cells and improves therapeutic efficacy. This study establishes the use of magnetic carbon nanotubes as a treatment option for GBM.
