LONDON The Fraunhofer Research Institution for Electronic Nano Systems (Chemnitz, Germany) has demonstrated a flexible printed battery.
The development allows series connections of printed batteries for the first time, according to
Fraunhofer ENAS, and thus integer multiples of the nominal voltage of 1.5 volts are possible.
The battery system is zinc manganese of which some parts are disposable and can even be composted, Fraunhofer said. By using efficient printing technologies and the adaptation of the used materials, the production yield reaches almost 100 percent.
Printed batteries are suitable for thin and flexible products including tags and sensor cards, medical patches and plasters for transdermal medication and biomedical monitoring. The battery technology can be combined with flexible displays and solar cells where required.
The first application being targeted for volume production is expected to be in production in the fourth quarter of 2009.
