Abstract

A thermal device includes a first thermal unit, a second thermal unit, and device electronics. The first thermal unit includes a first plurality of semiconductor elements sandwiched between first and second thermal unit substrates. The first thermal unit substrate exchanges heat with a user. The second thermal unit includes a second plurality of semiconductor elements sandwiched between third and fourth thermal unit substrates. The third thermal unit substrate exchanges heat with the user. The device electronics are coupled to the first thermal unit and the second thermal unit. The device electronics operate the first thermal unit in a heating state in which the first thermal unit transfers heat to the user via the first thermal unit substrate. The device electronics operate the second thermal unit in a cooling state in which the second thermal unit removes heat from the user via the third thermal unit substrate.
