Stretchable electronics have broad applications, including wearable sensors and curved displays. However, the electronic performance of stretchable materials is poor in comparison to non-stretchable rigid electronic materials. In a new study, researchers have developed a new technique, using kiri-origami structures, that combines the benefits of both origami and kirigami to achieve stretchable devices with high-performance non-stretchable materials. This innovative technique can lead to the development of advanced stretchable electronic devices.

In the Materials Horizons Emerging Investigator Series, Dr. Eunho Lee from SeoulTech talks about his recent study on novel organic semiconductor materials with glycol side chains that enhance artificial synapses by shifting from surface-limited to bulk-mediated ion transport mechanisms. The research demonstrates how molecular design of conjugated polymers can improve synaptic performance in neuromorphic computing devices, offering pathways toward brain-inspired artificial intelligence hardware.

Embedded systems such as Internet of Things (IoT) devices and single-board computers require careful memory allocation management. In a recent breakthrough, SeoulTech researchers have proposed LWMalloc, a lightweight dynamic memory allocator designed for resource-constrained environments like IoT devices and embedded systems. The research demonstrates up to 53% faster execution times and 23% lower memory usage compared to Linux's default allocator, while requiring only 530 lines of code versus ptmalloc's 4,838 lines.
