From Solution to Innovation: Flexible & Formable Silver Nanowire Based Inks for Transparent Electronics

In this presentation we will provide an overview of Activegrid™- a highly flexible and stretchable silver nanowire-based transparent conductor (TC) that rivals—and often exceeds—the optoelectronic performance of traditional brittle sputtered TCs like indium tin oxide (ITO).

Activegrid ink can be deposited from solution using various high-speed low-takt-time methods and processed at much lower temperatures (as low as 25C) compared to other TCs. It has already been commercialized in some of the world’s first mass-produced flexible consumer electronic devices, primarily serving as the TC for capacitive touch sensors.

Activegrid has also been prototyped, qualified and designed into applications ranging from smart windows, EMI shielding, and photovoltaics, to next-generation displays, and even biomedical devices.

An advanced generation of Activegrid is now being commercialized for various automotive applications, especially in transparent heating for LiDAR and camera sensors, offering significant performance and processing advantages.

Finally, we will also highlight some very unique properties of highly concentrated silver nanowire based inks and dispersions under development which exhibit remarkable electrical, and rheological properties and may also enable a variety of next generation electronics.
