“…Humidity detection is another application of 5G radio sensing. In [82] and [83], on-body humidity sensing antenna was designed at the 38 GHz frequency by detecting the dielectric constant of polyimide and changes in resonant frequency. UAV detection becomes a popular area in recent years, due to many unauthorized UAV flights and safety concerns.…”

This manuscript demonstrates a comprehensive analysis of a low-profile dual-band flexible omnidirectional wearable antenna, designed for Wireless Body Area Network (WBAN) applications. The proposed antenna is designed and fabricated on a commercially available semiflexible RT/duroid 5870 substrate. The antenna prototype is composed of a circular radiating patch with a star-shaped slot at the center, providing dual-band operations that resonates at the 2.45 GHz ISM band and 5.2 GHz WLAN band. Meanwhile, two truncated arc-shaped slots at the top and bottom edges of the radiating patch and the partial ground were utilized to improve the reflection coefficients (S11) and impedance bandwidth of the antenna. The proposed antenna has a compact footprint of 47×30×0.787 mm 3 (0.38 λo × 0.25 λo × 0.006 λo at 2.45 GHz), with measured impedance bandwidth of 48% and 38.5% at 2.45 GHz and 5.2 GHz respectively. Moreover, the designed antenna has an omnidirectional and bidirectional radiation feature with the estimated gain of 2.5 dBi, 4.63 dBi and numerical efficiencies of 98.5% and 95% at 2.45 GHz and 5.2 GHz respectively. Furthermore, a comprehensive investigation encompassing a specific absorption rate and an exploration of bending aspects validated the effectiveness of the suggested design in adhering the SAR threshold and its remarkable robustness, when confronted with the demands imposed by human body loading and structural deformations. Consequently, both the numerical and measured results strongly endorse the significance of the suggested design for lightweight, body-worn wearable devices within the Wireless Body Area Network applications.

Polyimide (PI) is one of the most dominant engineering plastics with excellent thermal, mechanical, chemical stability and dielectric performance. Further improving the versatility of PIs is of great significance, broadening their application prospects. Thus, integrating functional nanofillers can finely tune the individual characteristic to a certain extent as required by the function. Integrating the two complementary benefits, PI-based composites strongly expand applications, such as aerospace, microelectronic devices, separation membranes, catalysis, and sensors. Here, from the perspective of system science, the recent studies of PI-based composites for molecular design, manufacturing process, combination methods, and the relevant applications are reviewed, more relevantly on the mechanism underlying the phenomena. Additionally, a systematic summary of the current challenges and further directions for PI nanocomposites is presented. Hence, the review will pave the way for future studies.
