[14a-A408-5] Liquid-state Stretchable Device Using Liquid Metal
Keywords:Stretchable device, Liquid metal
Stretchable devices have many potential applications in wearable electronics, robotics, health monitoring, and more. Mechanically deformable devices and sensors enable conformal coverage of electronic systems on curved and soft surfaces. Sensors utilizing liquids confined in soft templates as the sensing component present the ideal platform for such applications, as liquids are inherently more deformable than solids. A new approach utilizing the concept of “liquid-state electronics” with conductive liquids for stretchable sensors has been proposed. Here, we report five stretchable sensors using liquid metals, highly sensitive pressure sensor based on the Wheatstone bridge, and temperature, humidity, oxygen, light sensors with liquid-liquid “heterojunction”. This report will present an important advancement towards the realization of liquid-state electronic systems.
