Abstract

Extensive research is currently underway across the world for employing piezo sensors for biomedical health monitoring in view of their obvious advantages such as low cost,fast dynamics response and bio-compatibility.However,one of the limitations of the piezo sensor in bonded mode based on the electro-mechanical impedance (EMI) technique is that it can cause harmful effects to the humans in terms of irritation ,bone and skin disease. This paper which is in continuation of the recent demonstration of non-bonded configuration is a step towards simulating and analyzing the non-bonded configuration of the piezo sensor for gauging its effectiveness using FEA software. It has been noted that the conductance signatures obtained in non-bonded mode are significantly close to the conventional bonded configuration, thus giving a positive indication of its field use.
