Stretchable printed circuit board (S-PCB) is critical for the realization of stretchable electronics including soft robotics, wearable technologies and biomedical applications. Since S-PCB is responsible for the connection between electrical components, S-PCB should have high electrical conductivity, negligible resistance change during stretching and tough bonding with rigid electronic components. To address this need, I suggest liquid metal particle assembled network (LMPNet), a stretchable conductor with record-high conductivity (2.10×106 S m-1), extreme stretchability (4,000%), high mechanical toughness (27.94 MJ/m3) and reliable interface (588 J/m2) with other surfaces. Based on superior properties of LMPNet, I demonstrated stretchable display and stretchable health-monitoring system with S-PCB consisted of LMPNet.
