High-Resolution Stretchable Soft Liquid Metal Circuits Based on Cu–Ga Alloying and Femtosecond Laser Ablation

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: March 13, 2025

Flexible electronic circuits are critical in biomedical devices, human–machine interfaces, and wearable sensing systems, which further require flexible conductive materials with high conductivity, stretchability, electrical stability. Liquid metal (LM) has attracted much attention due to its unique metallic conductivity room-temperature fluidic properties. However, LM's surface tension properties increase the difficulty of patterning processing. Here, we report a scalable simple fabrication method based on femtosecond laser ablation for facile patterned LM Cu composite electrodes (LM@Cu) substrates. The LM@Cu electrodes, fabricated utilizing exceptional micro–nanoprocessing precision three-dimensional capabilities lasers, exhibit resolution (approximately 5 μm), superior (4.08 × 104 S/cm), enhanced In addition planar circuits, successfully 3D-patterned electrode PDMS hemispheres. presence ultrathin copper foils significantly improves wettability substrate, occurrence alloying reactions between circumvents challenges posed by pattern fabrication. We investigated electromechanical under twisting, bending, stretching detail. addition, serve as an interface rigid devices When suffering external damage, remain working after brush coating excellent fluidity LM. To explore this approach's potential, demonstrate various applications electronics, including stretchable luminous wristbands, strain sensors, "visible" thermotherapy panels relieving aching joints.
