We describe how mechanical strain is able to control the flow of heat on a graphene sheet, since this material can either absorb or expel heat from/to a thermal reservoir, depending on the strain energy. In a similar fashion as the magneto- and electro-caloric effects, the present case considers the fact that a mechanical strain produces a pseudo-magnetic field that, on its turn, is responsible for the barocaloric effect. This result pushes graphene to the list of multicaloric materials.
我们描述了机械应变如何能够控制石墨烯片上的热流，因为这种材料可以根据应变能从热库吸收热量或向热库释放热量。与磁热效应和电热效应类似，在当前情况下，考虑到机械应变会产生一个伪磁场，而这个伪磁场反过来又会导致压力热效应。这一结果将石墨烯列入了多热材料的名单之中。
