Generation of piezoelectricity from the human body

Bones are the integral part of human body that shows piezoelectric properties. It means that when mechanical stress or mechanical excitation is applied to human body, this mechanical excitation directly affects the bones in body. Due to this excitation bones produce a current within itself which is a human bone property called as piezoelectric effect also known piezoelectricity. It is ability of certain materials for generating AC voltage when it is subjected to mechanical excitation or vibration. Human bones are made up of piezoelectric material thereby when human comes under mechanical excitation, AC voltage sets up in whole body due to piezoelectric effect in bones. A current starts flowing in all parts of body thereby the aim of our research is to determine the electrical conductivity in human body to establish the maximum voltage of 30–60 volts so that this produced piezoelectric charge could be stored in our designed human electricity sensor device. The major goal of our paper is to find out nature and amplitude of produced electric voltage signal waveform from human body and make it storable.
