A Multilayered GaAs IPD Resonator with Five Airbridges for Sensor System Application.

ABSTRACT: This work proposes a microwave resonator built from gallium arsenide using integrated passive device (IPD) technology. It consists of a three-layered interlaced spiral structure with airbridges and inner interdigital structures. For integrated systems, IPD technology demonstrated outstanding performance, robustness, and a tiny size at a low cost. The airbridges were made more compact, with overall dimensions of 1590 × 800 µm² (0.038 × 0.019 λg²). The designed microwave resonator operated at 1.99 GHz with a return loss of 39 dB, an insertion loss of 0.07 dB, and a quality factor of 1.15. Additionally, an experiment was conducted on the properties of the airbridge and how they affected resistance, inductance, and S-parameters in the construction of the resonator. To investigate the impact of airbridges on the structure, E- and H-field distributions of the resonator were simulated. Furthermore, its use in sensing applications was explored. Various concentrations of glucose solutions were used in the experiment. The proposed device featured a minimum detectable concentration of 0.2 mg/mL; high sensitivity, namely, 14.58 MHz/mg·mL^-1, with a linear response; and a short response time. Thus, this work proposes a structure that exhibits potential in integrated systems and real-time sensing systems with high sensitivity.

Project description:Tissue engineering is an essential component of developing effective regenerative therapies. In this study, we introduce a promising method to create scaffold-free three-dimensional (3D) tissue engineered multilayered microstructures from cultured cells using the "3D tissue fabrication system" (Regenova®; Cyfuse, Tokyo, Japan). This technique utilizes the adhesive nature of cells. When cells are cultured in nonadhesive wells, they tend to aggregate and form a spheroidal structure. The advantage of this approach is that cellular components can be mixed into one spheroid, thereby promoting the formation of extracellular matrices, such as collagen and elastin. This system enables one to create a predesigned 3D structure composed of cultured cells. We found that the advantages of this system to be (1) the length, size, and shape of the structure that were designable and highly reproducible because of the computer controlled robotics system, (2) the graftable structure could be created within a reasonable period (8 days), and (3) the constructed tissue did not contain any foreign material, which may avoid the potential issues of contamination, biotoxicity, and allergy. The utilization of this robotic system enabled the creation of a 3D multilayered microstructure made of cell-based spheres with a satisfactory mechanical properties and abundant extracellular matrix during a short period of time. These results suggest that this new technology will represent a promising, attractive, and practical strategy in the field of tissue engineering.
