Summary:A temperature control device 2 comprises a number of active thermal sites 6 disposed at respective locations on a substrate 10, each comprising a heating element 13 for applying a variable amount of heat to a corresponding site of a medium and a thermal insulation layer 16 disposed between the heating element and the substrate. At least one passive thermal region 8 is disposed between the active thermal sites 6 on the substrate 10, each passive thermal region 8 comprising a thermal conduction layer 18 for conducting heat from a corresponding portion of the medium to the substrate 10. The thermal conduction layer 18 has a lower thermal resistance in a direction perpendicular to a plane of the substrate 10 than the thermal insulation layer 16. This enables precise control over both heating and cooling of individual sites in a flowing fluid, for example.
