In this post, we will be reflecting on the journey throughout adopting Jr. Roger as our pet ans what has it inspired us for the past 12 weeks.
In the beginning when we adopted Roger, the shop keeper said that we should change his water once a day. Thus, we decided to do an experiment on him, which is not changing his habitat water for 2 weeks. This showed a clear result that Roger is still able to grow, live and adapt in an unfavourable environment. With this result, we believe that this is closely related to function of the frog's skin which allows roger to filter the unwanted substances from entering its body. The findings had led us to study the structure of frog skin which we found that only water, carbon dioxide and oxygen can passes through the frog skin because of the alveoli that are located at the surface of the skin.
As we know, alveoli is also located in human's lungs. It is used to purify and filter the air that we inhaled for the blood to get oxygen. This is also the reason that human will not get blood cancer but lungs cancer when that always inhale dirty gases.
With these findings, we came out with an idea of air purifier from mimicking the frog's skin.
Previously, one of our groupmates, She-Reen and her group of friends had designed an air purifier in her previous project. In their design, HEPA filter was used to filter particulate matters. The idea of mimicking the structure of the epithelium cell of the frog skin will allow gaseous exchange and filtration to happen naturally with sustainability. If the invention is successful, the newly invented filter based on the frog's skin can replace the HEPA filters used in the air purifiers in the market.
