Thermoelectric generators enable to receive usable electric energy from temperature gradients. When placed between a cold and a warmer surface these generators produce electric energy from the heat flowing through the generator. Manufacturing thermoelectric generators (TEG) is still expensive and in addition, conventional TEGs are rigid and sometimes contain toxic, rare or expensive materials. For printed thermoelectrics we use non-toxic polymers with a thickness of 20 to 30 micrometers.

To evaluate the efficiency of developed thermoelectric materials we offer thermoelectric modules in different designs ready to fit for respective application.
