A research team led by Professor Sung-Min Park (Department of IT Convergence Engineering, Mechanical Engineering, Electrical Engineering, and Graduate School of Convergence Science and Technology) and Dr. Sunguk Hong (Department of Mechanical Engineering) at POSTECH (Pohang University of Science and Technology) has developed a spinal cord stimulator that remains rigid during insertion but softens upon contact with bodily fluids.

The findings are published in npj Flexible Electronics.

Chronic diseases like hypertension and diabetes are often attributed to lifestyle or genetics. However, recently, the medical community has increasingly recognized “neural imbalance” as a fundamental cause. This is why neuromodulation—restoring the body’s regulatory functions by sending electrical signals directly to nerves—is emerging as a powerful alternative to traditional drug therapy.
