The results have now been published in Nature Communications.

“We are the first in the world to present a logic circuit, in this case a transistor, that is controlled by a heat signal instead of an electrical signal,” states Professor Xavier Crispin of the Laboratory of Organic Electronics, Linköping University.

Possibilities for new applications

The heat-driven transistor opens the possibility of many new applications such as detecting small temperature differences, and using functional medical dressings in which the healing process can be monitored.
