The chemical department of IIT Bombay has developed a biosensor that works on conducting polymers. These types of sensors can check the presence and quantity of various elements in a liquid. Media Lab Asia took this project for further development and appointed people from various departments like electrochemistry, microelectronics, biomedical, industrial design centre of IIT Mumbai, and people from Media Lab Asia. I took this project under the guidance of Prof. Munshi of IDC, IIT Bombay. The project's main aim was to do research in water quality checking. On every Friday, a meeting is used to be held in the Chemistry department where all the people in the group meet and discuss various issues of design at various levels of sensor design. Group looks on to the progress of every person. Inputs are given from experts in different fields and are used in the design of the product. The project's main aim is to develop a water quality checking product that can be carried in fields outside the laboratory. Each and every technical issue is discussed in a meeting, and solutions for problems were finalised by consulting with the people. The effort is to make such a product that is useful to people who are doing research in this field. Exploration for design ideas was done in many ways. At every level of design, concepts were evaluated and then carried forward.
