Button cell scanner

According to the statistics, in Australia four children per week on average go to an emergency department or hospital after swallowing a button cell battery. Children under five face a greater risk and the majority of them cannot clearly descrbe the object they have swallowed. Therefore, in this thesis I aim to design a button cell scanner for doctors and families so that the swallowed object can be identified as soon as possible and surgery performed if needed. In this project, I did substantial research on the difference between button cells and coins which are similar in material and sharpness, as well as into feasible methods to solve the problem. Finally, prototypes are manufactured according to the feasible design and improvements. This document reports work that I have done this semester as well as problems that arose from the experiments.
