Summary:Piezoelectric tubes with various dimensions were using the electrophoretic deposition process. The are for use as actuators in fibre-optic switches require a tip deflection of at least 65 micron. maximise the tip deflection of the tubes and to multiple-direction switching, the tubes had a electrode arrangement and, therefore, new equations were needed to analyse their tip Equations for thick-walled and thin-walled tubes were developed by modifying existing which could be used to estimate the performance new tubes and to optimise their dimensions for applications. Experimental verification showed the new equations gave a good estimation of the piezoelectric tubes' deflection. The advantages limitations of the modified equations are also
