Materials intelligence (Ih(50)) of tourmaline and piezo electric materials.
Ayumu Yazawa, Kazuya Oguri, Yoshitake Nishi · Journal of Advanced Science · 1996
Based on functions of human being, the materials intelligence (Ih(50)) has been suggested, and the Ih(50) and practicality (Pr) were evaluated. When the Ih(50) and Pr values are 1.0 for the intelligent materials, the values [Ih(50), Pr] are [0.38, 0.7] for tourmaline and [0.33, 0.75] for piezo electric materials, respectively.
