Abstract
Disclosed is a pressure determining unit configured for determining a pressure of a fluid. The pressure determining unit comprises a body structure and a deformation detector. The body structure has a fluidic path configured for conducting the fluid, wherein the body structure has a first surface in a first dimension and in a second dimension, and a thickness in a third dimension. The deformation detector is configured for responding to an elongation into the second dimension of the first surface of the body structure by generating a signal indicative of a value of the pressure of the fluid in the body structure. The fluidic path of the body structure comprises one or more first channel segments, each first channel segment having a height into the third dimension being at least twice of its width into the second dimension.
