Water-based nanoprinting moves metal films onto delicate 3D surfaces without damage

A new technology allows metal circuits floating on water to be transferred directly onto any desired surface. A South Korean research team has introduced a novel technique capable of transferring ultra-fine nanocircuits onto plant leaves and fruits, as well as curved automotive surfaces and robot exteriors, all without causing any damage. This technology could be widely used across industries, including smart agriculture, wearable health care and bioelectronics.
