Material design for Stretchable Electronics

  • Stretchable Conductor

 Stretchable electronics are having great interests because of their wide availability in wearable devices, soft robotics, and implants. For the stretchable electronics, one of the most important and fundamental components is stretchable conductor. Stretchable conductor must maintain their original mechanical, and electrical performance despite of the stretching cycles. Our lab research aims the development of structural, and intrinsically stretchable conducting materials as a basic component for stretchable electronics for the actual use of display, transistor, sensors, and batteries. The materials include metallic hybrid materials which are composed of 0-D, 1-D, 2-D nanomaterials and stretchable polymer, in addition, organic conductive material such as PEODT:PSS.

  • Stretchable Electroluminescent & Electrochemical System

  As interest in human-friendly devices grows, interest in the development of displays that enable visual communication between electronic skin system and human is also increasing. In addition, there are growing demands for new displays that require folding/stretchability, such as curved lighting, various forms of the Internet of Things (IoT) displays, and electronic skins.

 Our lab designs stretchable display systems such as alternating current electroluminescent (ACEL), and light-emitting electrochemical (LEC) devices, through various materials and structural approaches.
