CERAGEM Co. said on the 30th that a study jointly conducted by the company's clinical research team and the CERAGEM-KAIST Future Healthcare Center was published in the March 2026 issue of the SCI-listed international journal Annals of Biomedical Engineering.
CERAGEM Co. Clinical is CERAGEM Co.'s specialized clinical research institute. The CERAGEM-KAIST Future Healthcare Center is a joint research organization established by CERAGEM Co. and KAIST in 2021 that is advancing medical appliance technologies and developing next-generation healthcare solutions.
The study applies technology used in limb compression circulation devices employed in clinical settings. The existing 3D simulation method divides the human body into numerous small units (grids) and calculates each one, making computation complex and time-consuming, which has limited the optimization of medical devices that reflect individual physical characteristics.
To overcome these limitations, the joint research team developed a "multi-fidelity fluid-structure interaction modeling" approach and focused the study on verifying the suitability and accuracy of the model.
This technology uses a "hybrid (1D+3D) simulation method" that reflects both body structure and blood flow, analyzing complex parts precisely in 3D and handling simpler parts in 1D to improve efficiency. As a result, it achieved computation speeds up to 46 times faster than conventional methods while maintaining accuracy, enabling more efficient validation in clinical trial design and result analysis.
In particular, the study secured foundational technology to implement simulations that reflect individual differences in body shape and blood flow characteristics at a "near real-time" level. This allows for quantitative analysis and prediction of deep venous blood circulation during device operation, enabling more precise evaluation of therapeutic efficacy and safety.
Based on the technology secured through this study, CERAGEM Co. Clinical plans to develop it into a control technology that optimizes compression intensity and location according to the user's physical condition, and to expand its application to CERAGEM Co.'s spine care medical devices, massage chairs, air cell massagers, and future medical wearable devices.
