摘要

The device for monitoring temperatures comprises a container (1) incorporating an ultraphobic (both hydrophobic and oleophobic) surface (4) with protrusions (5) and depressions (6), holding a liquid (2) with a temperature dependent expansion coefficient and a capability of wetting under pressure the ultraphobic surface, and a gas cushion (3) located between the ultraphobic surface and the liquid.
