Communication System Design Using Synthetic Photoisomerizable Azobenzene-Regulated K ⁺ (SPARK) Channel

Biomolecules exhibit a remarkable property of transforming signals from their environment. This paper presents a communication system design using a light-modulated protein channel: Synthetic Photoisomerizable Azobenzene-regulated K+ (SPARK). Our approach involves a comprehensive design incorporating the SPARK-based receiver, encoding methods, modulation techniques, and detection processes. By analyzing the resulting communication system, we determine how different parameters influence its performance. Furthermore, we explore the potential design in terms of bioengineering and demonstrate that the data rate scales up with the number of receptors, indicating the possibility of achieving high-speed communication.
