Thermal probe (10) for a scanning thermal microscope (100), use, and process of manufacturing. The thermal probe (10) comprises a single-material (M1) thermal conducting body (12) consisting of a probe frame (14) ending in a probe tip (11). A bi-material (M1,M2) cantilever strip (13) is connected to the probe frame (14) in thermal communication with the probe tip (11). The cantilever strip (13) in unbended state lies in-plane (X,Z) with the probe tip (11). The cantilever strip (13) comprises layers of material (M1,M2) having different coefficients of thermal expansion configured to bend the cantilever strip (13) with respect to the single-material thermal conducting body (12) as a function of the heat exchange (H) between the probe tip (11) and the microscopic structure (2) for measuring heat exchange (H) with a sample interface (1) by means of measuring the bending of the cantilever strip (13).
