The piezoelectric buttress that can be molded into an extended hexagon is composed to fit the torsional flow of a standard shoe sole, as described by Paradiso and Shenck Frontoni (2013) built another “gadget that can be worked in a shoe, and the gadget was assembled with piezo materials and perfusion polymers to run both the outdoor GPS tracker and the identification of radio recurrence “. (E. Frontoni, 2013).Gatto (2014) exposed “four separate arrangements of shoes savvy for the PVDF sheet to provide a GPS gadget .Hwang (2015) planned a piezoelectric floor tile in light of PZT piezo material, which are the transmission of vitality and a peak mass and springs, the power of 55 mW can be produced by examining the impedance (S.

Lee, S. P. Moon , 2015) “The soleplate was divided into 8 components that were associated in parallel, and each component can give a voltage of 2V in open circuit when 70kg of human weight wear a shoe” ( T. S. Gross and R. P. Bunch, 1988) Almusallam makes “a a screen printed piezoelectric shoe comprising a vitality generator using a flexible PZT polymer material (A.
Almusallam, R. N. Torah, D. Zhu, M.
J. Tudor and S. P. Beeby, 2013). Razian (2003) made a tricentered point transducer with 10 * 10 * 2.7 mm in PZT for the estimation of motive force (M.
A. Razian and M. G. Pepper, 2003). In addition, Geng (2010) developed “an essential piezoelectric transducer made of PZT, which was only 10 * 10 * 1 mm” (Zh.

). the same way a piezoelectric copolymer transducer (PVDF-TrFE) to evaluate pressure in the shoe and achieve a defenseless 10% goal ” ( A. J. Nevill, M. G.
