6 – Data Update

1 Reply

Our project started ambitiously with the goal of amplifying NFC signals, or reversing the nullification of NFC that occurs when a chip is backed with metal. Unfortunately we could not acquire thin enough materials (such as permalloy or ferrite foil/film) to properly test whether this was possible. We then pivoted and decided to test the range of data transfers when the NFC chip was backed with various materials of different electromagnetic permeability.

    I have a lot of questions about this data run. The headings for two different data runs are identical. What is different about them? It is okay to change your focus, but explain how you took the data. How are you initiating the data transfer? How do you know it was successful? You have a very interesting project. It is easy to get lost in the details and forget what your audience does not know.
