ABSTRACT
A simple experimental system was used to investigate the influence of pressure sensor height on the pressure measured under a bandage for an intrusive sensor placed on a cylindrical support structure. The height of the sensor was adjustable in the range 0 to 3.0mm. Pressure values derived from the sensor were significantly larger than the values expected from calculations based upon the ‘Law of Laplace’ for all sensor heights tested. The excess pressure indications for increasing sensor height is attributed to the so called ‘hammocking effect’. A simple model is developed to account for the increased pressures in terms of this effect.
