The first printed plastic magnetic field sensors


Conducting polymers just keep getting better. This week, Sayani Majumdar at Åbo Akademi University in Finland and pals say they’ve used using an inkjet printer to print a plastic circuit onto a plastic substrate that clearly shows magnetoresistance at room temperature.

That means they can print plastic microchips capable of sensing magnetic fields.  Cool, huh?
