Dielectric Properties of Eggshell Membrane of Some Select Bird Species

Dielectric constant, loss angle and dissipation factors were determined for eggshell membrane of some select bird species. The results revealed that eggshell membrane of Hen (local free-range fowl), Layer (agricultural farm fowl), Duck, Turkey and Quail has dielectric constant values of 6.016, 5.556, 6.809, 6.145 and 2.632, respectively, at frequency of 1 kHz. The dielectric constant values in each case were found to decrease with increase in frequency towards 3 GHz. Loss angle and dissipation factor also exhibited similar trend with frequency. The values of the eggshell membrane were observed to fall within the range of reported values of some known dielectric materials commonly put to use for production of capacitor. It has sustainability and is cheap to obtain. Hence, it is a good and recommended raw material for electrical and electronic industry for capacitor production.
