Present integrated stretchable electronics easily suffer from electrical deterioration and face challenges in forming robust multilayered soft-rigid hybrid configurations. Researchers in Singapore have developed a bilayer liquid-solid conductor (b-LSC) with amphiphilic properties that reliably interfaces with both rigid electronics and elastomeric substrates. The top liquid metal could self-solder its interface with rigid electronics at a resistance 30% lower than the traditional tin-soldered rigid interface. The bottom polar composite comprising liquid metal particles and polymers could not only reliably interface with elastomers but also help the b-LSC heal after breakage. The b-LSC fabrication could be scaled up by printing and subsequent peeling strategies, showing ultra-high strain-insensitive conductivity, extreme stretchability, and negligible resistance change under ultra-high strain. It could act as stretchable vertical interconnect access for connecting multilayered layouts and could be universally fabricated on various substrates with a resolution of ≈200 µm… read more.
