Chemical chip uses ions instead of electrons and holes

Chip integrates chemical, logic functions

An integrated chemical chip that could control and regulate the signal paths of cells in the human body has been developed by Klas Tybrandt, a doctoral student in Organic Electronics at Linköping University, Sweden.

It creates the basis for an entirely new circuit technology based on ions and molecules instead of electrons and holes.

The Organic Electronics research group at Linköping University previously developed ion transistors for transport of both positive and negative ions, as well as biomolecules.

Tybrandt has now succeeded in combining both transistor types into complementary circuits, in a way that is similar to traditional silicon-based electronics.
