Researchers got new breakthrough in new metal-elastomer composite, which can self heal and create new electrical connection that bypass the damage area. This new material does not only apply to robot, but also adjustable circuit, soft machine, biological inspiration robot and wearable electronics.
Before this research, the problem of soft and transformable circuit is easy to broke the soft structure, puncture or mechanical breakdown. That mean conductivity loss lead to circuit broke. This new material is a kind of soft silicone rubber and inside is Ga-In basis metal alloy liquid drop of micron size, which is liquid at room temperature.
