“…The antenna operating in free space achieves a maximum gain of 4.06 dB, while the antenna on the body reaches a gain of 4.93 dB. This slight gain increase could also be understood from the perspective of the body's dissipative nature [68,69].…”

The development of e-textiles necessitates the creation of highly conductive inks that are compatible with precise inkjet printing, which remains a key challenge. This work presents an innovative, syringe-based method to optimize a novel bio-sourced silver ink for inkjet printing on textiles. We investigate the relationships between inks’ composition, rheological properties, and printing behavior, ultimately assessing the electrical performance of the fabricated circuits. Using Na–alginate and polyethylene glycol (PEG) as the suspension matrix, we demonstrate their viscosity depends on the component ratios. Rheological control of the silver nanoparticle-laden ink has become paramount for uniform printing on textiles. A specific formulation (3 wt.% AgNPs, 20 wt.% Na–alginate, 40 wt.% PEG, and 40 wt.% solvent) exhibits the optimal rheology, enabling the printing of 0.1 mm thick conductive lines with a low resistivity (8 × 10−3 Ω/cm). Our findings pave the way for designing eco-friendly ink formulations that are suitable for inkjet printing flexible antennas and other electronic circuits onto textiles, opening up exciting possibilities for the next generation of E-textiles.

“…These progresses have allowed accommodating new challenging requirements, opening room for new applications at the same time. Among these advancements, wearable wireless devices can play a defining role in the development of a wide range of emerging applications, such as sports analytics [1], wellbeing and health monitoring [2,3], or positioning systems [4]. Generally, wearable wireless technology will have some form of communications capability, such as mobile communications, Bluetooth, or Wi-Fi that will allow the wearer to share and access to information in real-time.…”

Together with wireless technology, advances in nanotechnology and rapid and scalable synthesis of nanomaterials including the 2D graphene has transformed the realms of biomedical sciences. Recent research in the areas of drug delivery, cancer therapy, bio-sensing and bio-imaging have exploited the unique structural and physiological features of graphene and its different forms. Along with the Graphene, several other nanomaterials including carbon nanotubes (CNTs), make excellent candidates for applications associated with loading of drugs, cellular imaging, sensing other molecules and in-vivo cancer studies due to their biocompatibility and stability. Assimilating from the fundamentals of electromagnetic, wireless communication, medical and material science, a novel concept of nanonetworks was first introduced in 2008, which stems from the concept that a collection of nanodevices have the potential to harness the innate communication capabilities of the human body, thereby allowing them to cooperate and share information. It is anticipated that the advanced healthcare diagnosis can be realised if an efficient communication mechanism and data transfer are established between these nanodevices.

“…Among standards of communications, ultra-wideband (UWB) technology provides high capacity with large bandwidth signals, multi-path robustness and low-power systems. UWB antennas are ideal candidates for body-worn units in sports analytics [33], health monitoring [34][35] and positioning systems [36]. Thus, the effect of the presence of the human body has been studied several times while its impact on the performance of UWB antennas has been analysed [37].…”
