Provided is a method (400) of positioning a sweat sensor device (100), the method comprising: determining (410) a first skin location (i) of a mammalian subject, which first skin location (i) contains apocrine and eccrine sweat glands; determining (420) a second skin location (ii), adjacent to the first skin location (i), and having a different sweat gland composition than the first skin location, wherein at the second skin location (ii), predominantly eccrine sweat glands are present, and wherein the determining (410, 420) of the first (i) and second (it) skin locations is achieved by detecting differences between the first (i) and second (ii) skin locations; and positioning (430) the sweat sensor device (100) such that a first part of the sweat sensor device (100) is present on the first skin location (i), while a second part of the sweat sensor device (100) is present on the second skin location (ii).
