Summary: This article presents the design of a wearable textile antenna sensor for knee effusion diagnosis application. The antenna sensing patch region is embroidered using an automated computerized embroidery machine, while the design parameters were optimized using machine learning algorithms. The fabricated antenna sensor operates at a resonance frequency of 2.19 GHz and performs diagnosis based on the concept of reflection coefficient parameter. Additionally, the specific absorption rate (SAR) level of the sensor device is evaluated and kept below the safety limit value.

Summary: This article presents a dual functional dual patch wearable antenna integrated into a military beret for indoor and outdoor positioning. The antenna consists of an inner circular patch for global positioning systems and an outer square ring patch for radio frequency identification. The antenna is fabricated using felt as substrate and conductive metalized nylon fabric. The performance of the antenna is analyzed and compared with pre-published antenna systems, showing superior performance. The radiation effect on a human head is evaluated through specific absorption rate analysis.

Summary: Cell analysis at the single-cell level is crucial for understanding the heterogeneity within cell populations and the characteristics of individual cells. Microfluidic chip systems have been widely used for single-cell analysis due to their precise manipulation and sensitive detection capabilities. This review focuses on the optical technologies used in single-cell analysis on microfluidic chip systems, including fluorescence, surface-enhanced Raman spectroscopy, surface plasmon resonance, and interferometry. The recent applications and future directions of these optical technologies are discussed.

Summary: This work presents a compact and conformal frequency reconfigurable antenna for automotive applications. The proposed antenna is designed on a liquid crystal polymer substrate and utilizes coplanar waveguide feeding, circular ring radiating element, and parasitic circular elements. The antenna achieves multiband operation and can be reconfigured in the 4.5-6.5 GHz region using PIN diodes as switching elements. The study explores the bending and conformal effects of the antenna, making it suitable for connected driving scenarios.
