The 42^nd International Exhibition of Inventions, Geneva, took place from April 2^nd to 6^th in the year of 2014. The YunTech team was granted 2 gold and 2 silver awards among all the entrees, which showed the research and development power of the staff members and students of YunTech.

The awarded products are listed below:

The gold-awarded product, “Si-Ge Thin-Film Solar Cells with Poly-Germanium Thin Film and Method for Performing the Same,” was invented by students Hung Wei-chin, Li Chao-chen and Yang Ting-yu instructed by Associate Professor Li Jian-yang of the Department of Electronic Engineering. The purpose of this product was to improve the conversion efficiencies of solar cells. By adopting the researchers’ method, people don’t need expensive or high risky airs. It is believed the method eases the manufacturing process. If the method is applied to crystalline silicon solar cells, the energy-producing efficiency and the values of products will be higher.

The other gold-awarded product, “Preparation of Radar Absorbing Materials,” was invented by student Lin Pei-ju instructed by Associate Professor Nien Yu-hsun of the Department of Chemical Engineering. The graphene films on the market have the problem of multiple scattering due to their small sizes. Due to this problem, the main purpose of the invention is to help absorb most of the radar waves on a high frequency of X-Band. It is believed that the new absorbing materials can be applied for military uses, for example, radar absorbing and electromagnetic interference (EMI). Furthermore, the absorbing materials can be used for absorbing the electromagnetic wave radiation occurring in our daily lives, such as the electromagnetic waves from our cell phones, local area network (LAN), 3C appliances and so forth. With the materials, our health will be protected.  

The silver-awarded product, “Fly Catcher,” was invented by students Hung Rei-yung and Chang Shi-shun instructed by Associate Professor Wang Ching-liang of the Department of Creative Design. According to student Hung traditional covers of trash cans can only prevent the smell of trash, but can prevent fruit flies from producing new fruit flies and growing. The cover of Fly Catcher is in the shape of a funnel which causes fruit flies to fly into the trash can easily but makes it difficult for them to fly out. The smell of the trash inside the can will flow from the bottom through an air path. There are 3 sizes for the Fly Catcher, making it easy for everyone to choose the right sizes for their own trash cans.  

The other silver-awarded product, “Convenient Jelly,” was invented by students Hsieh Tsai-en instructed by Associate Professor Chang Tsen-yao of the Department of Creative Design. Student Hsieh integrated the concepts of jelly and jelly slipper to create a new product. By using Convenient Jelly, you don’t need to prepare another jelly slipper but still can plaster jelly on the bread or toast you are going to eat. The new design not only preserves jelly but also makes the jelly plastering easier and more convenient. Besides this advantage, the integrated design lessens the amount of trash, making it environmentally friendly and fulfilling the basic concepts of green design theory.
