Bio-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method of assessing your body composition, the measurement of body fat in relation to lean body mass.It is an integral part of a health and nutrition assessment. Research has shown that body composition is directly related to health.io-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method of assessing your body composition, the measurement of body fat in relation to lean body mass.
Piezoelectricity /piËeÉªzoÊËilÉkËtrÉªsÉªti/ is the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins) in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure. It is derived from the Greek piezo or piezein (ÏÎ¹Î­Î¶ÎµÎ¹Î½), which means to squeeze or press, and electric or electron (Î®Î»ÎµÎºÏÏÎ¿Î½), which means amber, an ancient source of electric charge. Piezoelectricity was discovered in 1880 by French physicists Jacques and Pierre Curie. The piezoelectric effect is understood as the linear electromechanical interaction between the mechanical and the electrical state in crystalline materials with no inversion symmetry.
