Ultrastretchable Electronics Utilized by Liquid metal and Highly Soft Elastomer |
| 초록 |
Stretchable electrical devices are compelling to be utilized for soft robotics, stretchable display and wearable electronics. A commercially available silicone (Exsil 100) that exhibits ultrastretchability (elongation at break of 5,000%), ultrasoftness (Young’s modulus of 0.02 MPa) and high tear strength (42 N/mm) is proposed as promising elastomer for fabricating soft and stretchable electronics, but the patterned structures are prone to collapse when they are released from the mold due to ultrasoftness of the materials. Herein, we developed ultrasoft and ultrastretchable electronics by non-lithographic approach with Exsil silicone and oxidized liquid metal as an elastomeric substrate and an electrode, respectively. The ultrastretchable elastomeric films patterned with highly oxidized liquid metal can find use in application of stretchable electronics such as soft robotics and pneumatics to wearable devices and sensors integrated with textiles. |
