Stretchable Optoelectronics

For next-generation wearable and skin-interfaced devices, stretchability is crucial to maintain reliable performance while ensuring user comfort during motion. The form factor of future displays and sensors must go beyond simple flexibility to accommodate large and repeated deformations without compromising optical or electrical stability.

However, achieving such mechanical compliance in optoelectronic systems remains challenging due to the intrinsic brittleness of active materials, interfacial delamination, and performance degradation under strain. Conventional strategies based on structural design often provide only limited deformability and are not sufficient for long-term operation.

Our group focuses on material engineering approaches to realize intrinsically stretchable optoelectronic devices. In particular, we develop stretchable active layers and compliant electrodes that integrate mechanical robustness with high optical quality, aiming to establish practical platforms for wearable and adaptive optoelectronics. By combining mechanical compliance with stable optical and electrical properties, our research opens pathways toward practical, industry-ready stretchable optoelectronic devices.
