PAPER BATTERY OFFERS POTENTIAL CHEAP SMART APPLICATIONS FOR FOOD AND DRINK PACKAGING
April 2nd, 2020 After 10 years of research, researchers at the Ångström Laboratory at Uppsala University in Sweden, working with Sweden-based paper packaging manufacturer BillerudKorsnäs, are close to the commercial development of a bio-based paper battery which would serve as a small energy source on paper packages. It could, for instance, power sensors measuring key food and drink qualities, such as temperature, pressure and light. The prototypes of their paper battery are made of electrodes based on cellulose from wood pulp fibres that can be integrated, like a small ...
