Gold wire is widely used in microelectronics as a conductive interconnect material, especially in semiconductor devices and integrated circuits. Its excellent electrical conductivity, resistance to oxidation, and high reliability under thermal cycling make it ideal for bonding connections between the silicon chip and the package leads. Gold wire is preferred in high-temperature or high-humidity environments where corrosion resistance is critical. In medical devices, gold wire serves in implantable technologies such as pacemakers and neurostimulators due to its biocompatibility and stable electrical performance. It is also used in specialized sensors and aerospace electronics where long-term stability and minimal signal loss are essential. Additionally, gold wire finds use in jewelry and decorative applications, particularly in high-end watchmaking and textile embellishment, where its malleability and luster are advantageous. In research and analytical instruments, it acts as a fine electrode material in electrochemistry and scanning probe microscopy.
