| contents | Molecular communication (MC) enables biocompatible and energy-efficient information transfer through chemical signaling, forming a foundational paradigm for emerging applications in the Internet of Nano Things (IoNT) and intrabody healthcare systems. The realization of this vision critically depends on developing advanced receiver architectures that merge nanoscale communication and networking techniques with bio-cyber interfaces, ensuring energy-efficient, reliable, and low-complexity modulation and detection while maintaining biocompatibility. To address these challenges, the Flexure-FET MC receiver was introduced as a mechanically transducing design capable of detecting both charged and neutral molecular species. In this study, we present a cylindrical nanowire array-based Flexure-FET MC receiver that enhances design versatility and scalability through distributed electromechanical coupling in a suspended-gate configuration. The proposed array architecture offers additional geometric degrees of freedom, including nanowire radius, length, spacing, and array size, providing a flexible framework that can be tailored to advanced MC scenarios. An analytical end-to-end model is developed to characterize the system's electromechanical response, noise behavior, and information-theoretic performance, including signal-to-noise ratio (SNR) and channel capacity. The results reveal the strong interdependence between geometry, electromechanical dynamics, and molecular binding processes, enabling tunable control over sensitivity, noise characteristics, and communication capacity. The enhanced structural tunability and array configuration of the proposed design provide a flexible foundation for future mixture-based and spatially modulated MC systems, paving the way toward scalable and multifunctional receiver architectures within the IoNT framework. |
