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.

确定了某些精选鸟类的蛋壳膜的介电常数，损失角和耗散因子。结果表明，在1 kHz的频率下，母鸡（本地散养禽），蛋鸡（农用禽类），鸭，土耳其和鹌鹑的蛋壳膜的介电常数分别为6.016、5.556、6.809、6.145和2.632。 。发现在每种情况下，介电常数值都随着频率朝3 GHz的增加而降低。损耗角和耗散因数也表现出与频率相似的趋势。观察到蛋壳膜的值落在通常用于制造电容器的某些已知介电材料的报道值的范围内。它具有可持续性，而且价格便宜。因此，
