2. What is sustainability Sustainability is based on a simple principle: Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment. Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations.

3. Electrical Engineering Department Importance Sustainability is important to making sure that we have and will continue to have, the water, materials, and resources to protect human health and our environment.

4. Electrical Engineering Department How to obtain sustainability? 1.Waste production: minimize the amount of waste produced during manufacturing process 2.Material management : use and reuse material in the most productive and sustainable way across their entire life cycle 3.Pollution prevention: reduce or eliminate waste at the source by modifying production processes, promote the use of reusable materials 4.Product enhancement: create better products that have longer lifetime to ensure less trash for environment.

7. Electrical Engineering Department Our project By using RFID technology, we reduce the antenna size which means we reduce the material cost. For most of the part, we use computer to do the simulation first then the fabrication. To maximize the material efficiency, we are going to use 3-D printing technology to rebuild the marker * Use copper tape instead of copper
