Characterisation of electromechanical response of forehead tissues due to fluid impact during shirodhara treatment

Shirodhara, an Ayurveda treatment, is idealised as an application of fluid impact on a piezoelectric plate completely bonded with another elastic plate. The human forehead is approximated as an isotropic homogeneous curved piezoelectric plate over another plate which is idealised as an elastic foundation. Displacement, stresses and voltages will be induced in the plate due to the impact of fluid. The fluids used for force analysis are Ksheerabala oil and Mahanarayana oil. A pure mechanical analysis was conducted to estimate displacements and stresses induced by fluid impact with different boundary conditions under static loading condition. Induced voltages due to fluid impact are estimated using appropriate piezoelectric constants. The implication of these generated voltages on the effectiveness of shirodhara treatment is discussed.
