The electrolyte strain along the cantilever's axis was calculated from the measured strain based upon the above equation. Given that the radius 𝑟𝑟 𝑎𝑎𝑎𝑎𝑦𝑦𝑐𝑐𝑎𝑎 of the electrolyte (0.25") is very small compared to the distance from the end of the bar (~18"), the strain state differs minimally at the edges of the electrolyte as compared to the center of the electrolyte (𝜀𝜀 𝑎𝑎𝑎𝑎𝑦𝑦𝑐𝑐𝑎𝑎 𝑎𝑎𝑎𝑎𝑔𝑔𝑎𝑎𝑒𝑒 = 𝐿𝐿 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒 ±𝑐𝑐 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒 𝐿𝐿 𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒𝑒 = (1 ± 0.014)𝜀𝜀 𝑎𝑎𝑎𝑎𝑦𝑦𝑐𝑐𝑎𝑎 ).
