Abstract :
The cartilage membrane of the human ear constitutes lipoproteins in bulk phases. The hydrophobic linkage of the polar heads of the lipids undergo spatial orientation in the presence of electrical stimuli both in bulk phases and in chloroform solvent. The relaxation properties of the human cartilage membranes for both males and females of age groups 20 years and 40 years have been found out in the present experiment with the help of a LCR meter (HP 4284A) programmed in the audio frequency range. It is interesting to note that the relaxation time constant increases with ageing of the membrane. The data obtained from the experimental setup comprising a three electrode system are corroborated satisfactorily for evaluation of the relaxation of the cartilage membrane
