Lee, also recognized as the father of K-pop star CL from the group 2NE1, has successfully conducted animal trials for a blood sugar measurement technique that doesn’t require drawing blood, Sogang University announced on October 21.

Working with Armenian researcher Zhirayr Baghdasaryan, Lee’s team developed a CCD camera sensor utilizing microwaves. In trials with rats, they achieved a remarkable accuracy of 7.05% MARD (Mean Absolute Relative Difference), a significant advancement in the field.



This development addresses long-standing concerns in the medical community about traditional blood glucose testing methods, which can be painful for patients and pose hygiene challenges. While alternatives using lasers, ultrasound, and osmosis have been explored, they’ve fallen short in accuracy and reproducibility. The research, published in the prestigious journal IEEE Access on September 28, marks a potential turning point in diabetes management.

However, the project faces an uncertain future. “Despite securing core technology and patents, follow-up clinical research has been halted after failing to secure funding from the Ministry of Science and ICT’s mid-career researcher program this year,” a Sogang University spokesperson explained. Lee’s integrity in research ethics came to public attention in 2021 when he revealed on a popular TV show that he had turned down a lucrative offer from Huawei for his diabetes research technology.

“There are things you should and shouldn’t do in this world,” he said at the time, emphasizing the importance of scientific conscience and loyalty to his country’s research investment. The physicist’s principles extend beyond his professional life. He’s also known for his progressive parenting approach, having supported his daughter CL’s decision to leave high school to pursue her music career.

“I thought I shouldn’t ask ‘why’. She must have contemplated it for a long time. I just said, ‘Okay, do what you want,’” Lee recalled.
