A vertically stacked thermopile and an IR sensor using said stacked thermopiles are provided. The vertically stacked thermopile may include multiple thermocouples stacked vertically on one another. The thermocouples may be connected in series, parallel, or a combination of series and parallel. One or more vertically stacked thermopiles may be included in an IR sensor and the thermopiles may be connected in series, parallel, or a combination of series and parallel.

Vertically stacked thermopile

Graphene-based thermopiles are provided. The graphene-based thermopiles may include thermocouples having one or more graphene strips that may be polarized to adjust their Seebeck coefficients. The polarized graphene strips may have larger Seebeck coefficients than the materials conventionally used in thermopile devices. As a result, the graphene-based thermopiles may generate large output voltages using fewer thermocouples than conventional thermopile devices.
