How microrobots should be translated: A clinical and value‐centered readiness framework

Abstract

Abstract Untethered mobile milli/microrobots hold transformative potential for interventional medicine by enabling more precise and entirely non‐invasive diagnosis and therapy. Realizing this promise requires bridging the gap between groundbreaking laboratory demonstrations and successful clinical integration. Despite remarkable technical progress over the past two decades, most millirobots and microrobots remain confined to laboratory proof‐of‐concept demonstrations, with limited real‐world feasibility. Here, we identify key factors that slow translation from bench to bedside, focusing on the disconnect between technical innovation and meaningful patient outcomes. We argue that the long‐term impact and sustainability of the field depend on aligning development with unmet clinical needs, demonstrating feasibility, value and integration potential into existing clinical workflows. To foster translational research of milli/microrobots, we introduce a strategic milli/microrobot Technology Readiness Level framework (mTRL), which maps system development from initial conceptualization to clinical adoption through clearly defined milestones and their associated stepwise activities. The mTRL model provides a structured gauge of technological maturity, a common language for multi‐disciplinary collaboration and actionable guidance to accelerate translational development toward new, safer and more efficient interventions.
