Fig. 2. Assembly process of a functional model of a low-cost pressure transducer consisting of a silicone tube, electrodes (copper-coated
polyimide flex board) and a PMMA alignment block to guarantee concentricity of the electrodes to the tube comprising of a standard silicone
tube, ID = 2.5 mm, WT = 0.2 mm, L = 5 mm which expansion behavior is characterized in [1].
