Intelligent sensors and automation are transforming dialysis technology by enabling real-time monitoring, adaptive control, and personalized renal replacement therapy. Conventional dialysis relies heavily on intermittent measurements and manual adjustments, often leading to complications such as electrolyte imbalance, intradialytic hypotension, and suboptimal solute clearance. Recent advances in sensor technology, automation, and data-driven control have enabled the development of intelligent dialysis platforms that continuously adapt to dynamic patient physiology. This chapter examines the role of intelligent sensors and automation in modern dialysis systems, with emphasis on their impact on safety, efficiency, and clinical outcomes. The chapter first traces the evolution of dialysis from traditional machines to smart, automated systems integrating biosensors, optical sensors, and electrochemical sensors for continuous monitoring of hemodynamic and biochemical parameters. Integration of microfluidic and nanoengineered sensors represents a major advance, allowing highly sensitive detection of uremic toxins, electrolytes, and metabolic biomarkers using minimal sample volumes, thereby improving dialysis adequacy and precision of solute removal. Closed-loop control systems are presented as a core component of automated dialysis, using real-time sensor inputs to dynamically regulate ultrafiltration rates, dialysate composition, and treatment duration. The incorporation of artificial intelligence and machine learning further enhances automation by enabling prediction of patient responses and individualized therapy optimization. The chapter also highlights the growing role of wearable and remote sensing technologies in supporting home dialysis and tele-nephrology, improving patient autonomy while maintaining clinical supervision. Finally, future directions include digital twin–based optimization, smart artificial kidneys, and autonomous dialysis systems, supporting safer, patient-centered renal care globally sustainably.
