MOSkin™ Precision Dosimetry System

Clinicians must verify skin-level radiation dose quickly, accurately, and without compromising treatment setup or patient comfort. Existing methods—TLDs and diodes—introduce workflow delays, require specialised processing, and create handling complexity. Electrogenics Labs sought to commercialise a breakthrough MOSFET dosimetry technology from the University of Wollongong into a hospital-ready product. D+I was tasked with developing an integrated system—under ISO 13485 design controls. Requirements included wireless single-use sensors operable in shielded LINAC environments with no sterilization needed. Constraints spanned user variability, mechanical robustness, radiation transparency for interventional procedures, system packaging, and enabling scalable production—all while reducing time-to-results from hours to minutes for the 90 million radiation treatments delivered annually.

Development involved close collaboration with medical physicists, radiation therapists, the inventors of the MOSFET technology, and clinical stakeholders at St George Hospital. Early research captured workflow constraints and identified user needs across roles. The physical system—comprising disposable skin sensors, a wireless hub, and iPad application—was iteratively developed under ISO 13485 design controls. Key challenges included aligning electronic and mechanical requirements, enabling reliable reader-to-sensor contact, and ensuring compatibility with treatment room infrastructure. The spring-loaded flap, compact housing, and charge indicator were refined through prototyping and feedback. The result is a manufacturable, clinical-grade system that enables accurate, near-instant dose monitoring without disrupting existing workflows.

MOSkin™ makes a protected academic invention clinically accessible—translating complex sensor research into a product used in hospitals by real patients. It improves safety by giving clinicians live visibility of delivered radiation dose, reducing risk of underdosing or toxicity. The single-use, wireless format improves patient comfort and allows for faster setup between sessions. Designed for scalable manufacture and integration into existing infrastructure, the system offers a commercially viable solution for high-volume radiotherapy and interventional markets. By reducing workflow delays and eliminating post-processing, it supports better care at lower cost—bringing a precision tool to routine cancer treatment across global healthcare settings.
