## Abstract The complex piezoelectric constant (__d__ = __d__β² β __id__β³), elastic constant (__c__ = __c__β² + __ic__β³), and dielectric constant (Ξ΅ = Ξ΅β² β __i__Ξ΅β³) were measured at a frequency of 10 Hz over the temperature range from β150 to 50Β°C and for a range of hydration up to 0.26 g/g for decal
The interaction of water with wood, such as bamboo and cedar, is investigated by measuring their complex piezoelectric, dielectric, and elastic constants between -150 and 150O C at 10 Hz. Bamboo and cedar are found to have two hydration-dependent elastic loss peaks, one is observed at about -looo C
