KU research group discovers the principles of in vivo thermopower generation

Professor Yoon Hyo-jae’s research team at Korea University has discovered that rubber plant leaves can naturally generate electricity through a phenomenon called the ionic Seebeck effect, without any additional processing. This effect occurs when moisture and ions within the plant tissues move in response to temperature differences, creating voltage. Notably, partially drying the leaves forms […]

Novel kiri-origami structures enable high-performance stretchable electronics

Stretchable electronics are increasingly used in devices like smartphones, smartwatches, curved displays, and wearable sensors, but they face a trade-off between flexibility and electrical performance, as stretchable materials like elastomers typically underperform compared to rigid ones like metals or semiconductors. To address this, researchers have turned to origami and kirigami—Japanese techniques of folding and cutting […]
