Ion Integrated Circuit

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 similar way to traditional silicon-based electronics.An advantage of chemical circuits is that the charge carrier consists of chemical substances with various functions. This means that we now have new opportunities to control and regulate the signal paths of cells in the human body.

“We can, for example, send out signals to muscle synapses where the signalling system may not work for some reason. We know our chip works with common signalling substances, for example acetylcholine,” says Magnus Berggren, Professor of Organic Electronics and leader of the research group.

That means we will be able to push chemical actuators 1 where needed to replace a damaged pathway, re-instantiating signals between the brain and muscle groups. There are some rather nifty servo-mechanical devices at in use already, but this might seriously mean nerve dead limbs could function again.

Totally awesome.
