A technology under development for five years by Xerox is making its way into healthcare and could change the way sensors to support connected health are designed.
Xerox developed a way to produce printed microcircuits using 3D printing and ink and thin circuitry printed to a Polyethylene terephthalate or PET substrate. The sensors are cheap to produce — costing roughly 10 cents to 15 cents — and can retain data for 10 years. Xerox calls its technology Printed Memory and it is currently in production.
Bill Compitello, senior account manager with Xerox Printed Electronics, said the technology was developed through a collaboration between Xerox PARC and Xerox Engineering in Webster, New York. In an interview at HIMSS with Compitello and Denise Fletcher, the chief innovation officer for healthcare and life sciences at Xerox, they talked about the applications for the sensors they envision.
When Investment Rhymes with Canada
Canada has a proud history of achievement in the areas of science and technology, and the field of biomanufacturing and life sciences is no exception.
It licensed the technology from Thinfilm.
Compitello said the technology is connected to Xerox’s history of printing photo receptors and was a logical move for the business.
Fletcher said the printed memory technology could provide an authentication function. Pharmaceutical companies will use printed memory to verify whether prescription medication is counterfeit. A tracking label combining a QR code with its printed memory would be read by a scanning device connected to a smartphone and possibly a cloud database.
It is also talking with a couple of companies in the medical device industry to verify the authenticity of test strips used for blood glucose monitors by diabetics.
Luxury brands, such as a high-end watch maker, will embed the printed sensors to verify that it is the manufacturer’s watch and not a fake.
Some of the other applications it is exploring are patient wristbands to verify the identification of patients in hospitals to ensure they get the correct medication and treatment. Fletcher said the sensors could also be embedded into apparel and wearable devices, potentially reducing the cost to produce them. It considers the printed memory technology as belonging to the realm of the Internet of Things.
