  • Non-uniform
  • GOAL : overcome thermal and power constraints in electronics. The company has patented thin-film cooling technology and power generation
  • Can be integrated directly into electronic and optoelectronic packaging.
  • converts heat directly into electricity. 
  • Traditional bulk thermoelectric are made with 1mm3 pellets. In contrast Nextreme replaced that by a thin-film that is just micrometers thick
  • To much variation in the heat can affect wavelength integrity. Size is a major stake. The devices become smaller and smaller but the TEC did not manage to keep that pace
  • As the junction temperature rises, a significant loss of light output (luminosity) can be expected.. Increases the performance and longevity of LED devices
  • are used in missile guidance sensors and thermal imaging; are widely used by the U.S. military and others for night vision goggles, These sensors detect wavelengths in the near and far infrared that are not visible to the naked eye.
  • measurement while drilling cooling ; environment of 230˚C
  • Heating reduction is a major stake in this specific stage of die manufacturing
  • is a technique to produce millions of copies of a specific DNA sequence in a short period of time. The vast majority of PCR methods use thermal cycling, i.e., alternately heating and cooling of the DNA sample based on a predefined series of temperature steps. A thermal cycler is an automated instrument specifically designed for this purpose.
  • They had a succesful experience in Chronos
  • A bunch of investors: nt only VCs but also a supplier for the CIA and a Japanese trader in technology products
  • Nextreme: a startup specialized in thermoelectric cooling
