Method of Wireless Communication using Thermoelectric Generators

A method comprising:

• receiving a first logic signal having one of a first state or a second state;
• generating a first thermal gradient in a first thermocouple in response to the first logic signal being in the first state;
• communicating the first logic signal by generating a second thermal gradient in a second thermocouple, the second thermal gradient caused by the first thermal gradient in the first thermocouple;
• generating a second logic signal based on the second thermal gradient, the second logic signal having a value that corresponds with the first state of the first logic signal;
• and
• using the second logic signal as an input to a control circuit.

A method comprising:

• placing an interposer over a printed circuit board, the interposer comprising:
• an interconnect region that comprises a plurality of metallization layers;
• a first thermoelectric generator disposed under the plurality of metallization layers;
• a second thermoelectric generator disposed under the plurality of metallization layers;
• and
• placing a first die and a second die over the interposer;
• wherein the first die includes a signal input coupled to an electrical input of the first thermoelectric generator;
• wherein the first thermoelectric generator is thermally coupled to the second thermoelectric generator;
• and
• wherein the second die comprises a signal output coupled to an output of the second thermoelectric generator.
