I am making some leather wearables with multiple sensors and nfc tags to save everything from links and business cards to encrypted data (about 6k). The important things that I need is flexibility (literally) and over 6k of storage along with small size and the flexDF meets all requirements. As technology is continually improving I am trying to find a way to hack one's physical abilities while not making modifications that while cutting edge today might leave the user stuck in past with the only option of cutting their hand open to upgrade themselves. I want to make an incredibly thin high quality leather patch/second skin that stretches over small parts of the body, something like the wrist or parts of the arm, with sensors in between the two "skins" so that you may both be biologically enhanced and easily upgradeable.
Would you mind telling me what price you would settle on and when I might buy these wonders of technology?
