TOPPAN FORMS CO., LTD. Develops Advanced Printed Microwire Technology
TOPPAN FORMS CO., LTD., based in Tokyo (Japan), has recently developed a technology for the production of printed microwires that is suitable, for example, for use in touch sensor panels. This innovation represents a significant advancement in the field of printed electronics and is poised to have a considerable impact on the industry.
Transparent electrodes
The newly developed technology combines conductive ink with a specialized printing process to produce microwires that are just 4μm (micrometer) wide. These microwires, made from silver salt ink, serve as transparent electrodes, offering a superior alternative to the previously used Indium Tin Oxide (ITO). This makes them ideal for integration into devices with wearable sensors, IoT sensors, and touch panel sensors. The reduction in the size of these microwires from the conventional 10μm to 4μm is a crucial development. This smaller size meets the growing demand for increased power efficiency, reduced dimensions, and enhanced functionality in modern electronic devices.
