Self-healing soft electronics developed in the US

29th June 2021 12:02 am 28th June 2021 11:53 am Researchers at Virginia Tech University have developed a new type of soft electronics that can self-heal and be recycled at end of life. Current passes through a self-healing circuit. Credit: Alex Parrish, Virginia Tech The ‘skin-like’ circuits, developed at the university’s Department of Mechanical Engineering and Macromolecules Innovation Institute, aim to pave the way for a new generation of reconfigurable, robust self-healing devices.  Led by assistant professor Michael Bartlett, the team’s approach replaces rigid materials and soldered wires currently used in consumer electronics with soft electronic composites and tiny electricity-conducting liquid metal droplets. The result is said to be a soft and stretchy circuit that can sustain ‘numerous damage events’ under load without losing conductivity.

Virginia Tech Researchers Build Soft, Stretchable, Self-Healing, Recyclable Electronic Circuits

Virginia Tech Researchers Build Soft, Stretchable, Self-Healing, Recyclable Electronic Circuits These novel circuits can be deformed any way you like, have a hole punched through them, and keep on ticking. a few seconds ago • Sustainability / Wearables A team of researchers from Virginia Tech claim to have developed a new form of soft electronics that can stretch, survive numerous damage events, and heal themselves automatically — and are even recyclable at the end of their lives. Described in the paper covering the team s research as a self-healing liquid metal composite, the new material aims to improve a number of aspects of current soft electronics — including their ability to operate while damaged and how recyclable they are once the device for which they are built is no longer needed.
