PLEASE READ INSTRUCTIONS CAREFULLY. ONLY NEEDS TO BE ONE AND A HALF PAGES ! ANSWER FOLLOWING QUESTIONS IN PARAGRAPH FORM BASED ON THE SUBJECT OF A SKIN WEARABLE DEVICE (TATTOO FOR IDENTITY) .ALSO WRITE A CONCLUSION BASED ON PORTION OF THE PAPER THAT IS ALREADY WRITTEN IN THE INSTRUCTION SECTION AND PARAGRAPH THAT YOU WRITE. Section 7: How much "running room" will you have? Running room or "runway" as it is sometimes known is how much cash you need to have on-hand/available until your business starts to make money and/or show a positive cash-flow. This is your deadline for making a profit.

Section 1: Based on the continued research that you and your team-mates have completed so far, review your originally postulated problem statement from your Week 1 Team Paper. Then, collaborate and write a more focused and directed problem statement. In essence, what problem have you identified? Why is this important to consider and discuss? The challenge up to this point, creating wearable electronics has required that the components on the device be flexible, themselves. This is no easy it can be a road block; however, after doing some research I found that researchers from Japan have finally succeeded in creating flexible semiconductors, but there are many more challenges for other flexible components. Another key point to discuss would be the idea of using a small chip; however, this might be a problem because it would have to be surface mounted. People may not want to have a surface mount resistor, led or capacitor on their body unless it can be inserted on the upper layer of their skin. Engineers in Japan instead of making the components flexible, they've made the electrical contacts that keep the components and printed silver on the membrane flexible. These keep the component connected, even when under flexing conditions. This allows for a tattoo to use parts already available to the electronics market. However, researchers at MIT are creating tattoos using gold foil as a conductor, cut to create traces on flexible vinyl material. Their tattoo circuit types fall into three categories: Input – Take inputs from the user including touch, temperature, and stress Output – The tattoo changes color depending on the surface temperature of the skin Communication – This tattoo is used for near field communication MIT researchers made these tattoos that can perform different functions.

This membrane, along with the flexible contacts, shows that the future of wearable electronics may not be in revolutionary materials but in finding ways to integrate such technology with already existing technology. Such an attitude in research may help get corporations to fund more projects as the likely hood of a return is significantly increased when the finished product can easily be manufactured and sold.
