Xerox says it has developed a conductive ink that creates a low-cost method to add computing power to plastic and other surfaces. One potential application is a “smart” pill box that tracks how much medication a patient has taken.
One of the technical breakthroughs was development of a conductive ink with a melting point below that of plastic. The silver ink has a melting point of 140C, compared to 267C for polycarbonate. Melting points for commodity plastics, such as polyethylene, are much lower and would not be used with the new inks.
Oak Ridge National Laboratory has developed a surface preparation method to improve joining carbon composites with aluminum, with potentially far-reaching ramifications for high-volume industrial applications.
