Formi continues to develop novel printed electronic solutions
When developing electronic devices, special considerations must be given to function, cost, and design flexibility. Formi 3DP has been working on various printed electronic technologies for both 3D and 2D applications. Our goal is to develop a high speed, low cost technology for the printed electronics industry. An example of our capabilities are showcased in the biomedical applications below, where we have developed a fabric based printed electronics solution that builds upon a new patent pending technology for printing high-performance flexible electronic circuits.
Fabrication process of fabric electrodes.
Step 1: pristine cotton fabric and P4VP are connected by polymeric graft chains containing epoxy groups.
Step 2: Silver ions are attached to P4VP because of the affinity of pyridyl groups.
Step 3: copper is deposited onto cotton fabric.
These fabric-based electrodes are extremely useful for many applications including motion detection or ECG measurements.
