FIELD: chemistry.
SUBSTANCE: disclosed is a method of detecting urine, which involves: using a urine sensor having a matrix, the matrix containing a thermochromic substance distributed therein and a temperature varying means, where said temperature varying means is capable of either raising temperature or lowering temperature upon contact with urine so as to cause temperature change in the thermochromic substance, resulting in colour change; contacting the urine with the sensor matrix; and determining presence of urine based on colour change of the thermochromic substance. A sensor for determining presence or absence of urine is also disclosed.
EFFECT: high accuracy and reliability of detection.
