Smart consumer packaging that lights up to showcase products on a shelf such as the backside of a Straub beer label is possible utilizing ultra-thin, wirelessly powered printed electronics from PPG and Powercast Corporation.

PPG and Powercast Corporation are paving way for the next-generation smart labels that offer identification as well as wireless illumination to showcase products on a shelf.

The companies have collaborated to produce ultra-thin and wirelessly powered printed electronics products. The solutions will combine PPG TESLIN substrate, PPG conductive inks and Powercast’s POWERHARVESTER receiver technology for delivering over-the-air wireless power.

The companies will introduce LED-based wireless illumination solutions for smart consumer packaging and smart identification (ID) cards, which enable enhanced security.

“With this technology, smart consumer packaging lights up to showcase products on a shelf. Smart ID cards also illuminate to permit or deny access to restricted areas or to verify user credentials”, according to the announcement.

The combined technologies allow developers to seal electronics into packaging and cards via lamination to provide indefinite illumination without wires, batteries, charging ports or direct contact with a power source.

“Powercast is excited to partner with PPG to deliver differentiation to the product packaging and secure credential markets,” said Charles Greene, Ph.D., chief operating and technology officer, Powercast. “PPG Teslin substrate and the company’s conductive inks have great radio frequency (RF) characteristics, which complement Powercast’s long-range wireless power technology.”

Wirelessly Powered, Printed Electronic Label for Consumer Goods

The illuminated products are created by printing graphics or information on one side of PPG Teslin substrate using conventional or digital print technologies. The electronic circuitry is printed directly onto the opposite side of the substrate using PPG’s conductive inks. The ultra-thin (1 millimeter or less) Powerharvester wireless power receiver chip and other components are then attached to the substrate using conductive epoxy, and the label is laminated to seal in the electronic circuitry.

Powercast’s embedded Powerharvester receiver chips harness RF energy wirelessly from a Powercast POWERSPOT transmitter or other RF source. The harnessed RF is turned into usable direct current (DC) energy to power embedded electronics and LEDs.

“A smart illumination solution using Powercast technology is a perfect complement to PPG’s current offering for secure credentials and label and packaging applications,” said Greg Terchick, PPG business director, Teslin substrate products. “The products we are developing with Powercast will enable our customers in these segments to create highly differentiated, value-added solutions for their customers.”

“The technology sharing between PPG and Powercast is an excellent example of the type of collaboration that continues to strengthen PPG,” said John Yundt, PPG global market manager, electronic and conductive materials. “We see this partnership as an ideal way to use the unique synergies of our broad portfolio of coatings and materials technologies to help our customers find solutions.”
