Dan Zhao and Simone Fabiano at the Laboratory of Organic Electronics, Linköping University, have created a thermoelectric organic transistor. A temperature rise of a single degree is sufficient to cause a detectable current modulation in the transistor. 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.
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.
It is also possible to produce circuits controlled by the heat present in infrared light for use in heat cameras and other applications. The high sensitivity to heat, 100 times greater than traditional thermoelectric materials, means that a single connector from the heat-sensitive electrolyte, which acts as sensor, to the transistor circuit is sufficient. One sensor can be combined with one transistor to create a "smart pixel."

TCC activation temperature: The temperature, measured at the CPU core(s), at which a PROCHOT# signal is sent. This is the signal that activates throttling of the CPU. In essence, the CPU will rapidly step down voltage and clock speed until temperature drops below the TCC activation temperature. If this doesn't work, the CPU will cycle the clock on and off repeatedly (effectively only remaining active a fraction of the time) to reduce temperatures.
