New highly sensitive flexible screen printed electrode (SPE) designed and developed for possible applications in chemical, biological and environmental species detection. The electrodes were screen-printed on a flexible polyester film using conducting inks.

Salient Features

1. The electrode is developed using a flexible polyester film substrate support material to make a highly sensitive electromechanical sensor. 

2. It is an indigenously developed, easy to fabricate, low cost electrode in comparison to commercially available expensive imported electrode. 

3. Experimental results are reliable and stable 

4. Wide scope of contribution to the other relevant supported projects like “MEMS based immune sensor for the determination of antigen”.
