A better RFID implant
As everyone one knows, one of the main issues with current RFID/NFC implants is their read distance. For some of us this probably isn't an issue as you use more powerful readers other than just a planer coil on a smartphone.
Personally, I would like my implant to become another seamless interface in my smartphone experience. Much in the same way that an on screen button or gesture would be used. For example, instead of swiping down my status bar and tapping a button to access the flashlight, it would be much cooler to put my phone over the back of my had for a quick second and have it turn on. Turning on your phone's flashlight with your implant can already be done to a degree, but it is just a little to finicky for my taste.
(Admittedly this is a pretty narrow minded example, but bear with me)
Regardless, I think they key to a better read distance is simply location and form factor.
The idea that I have had rolling around in my head is this:
- A flexible RFID that sits under the skin on the back of one's hand
- Could be rolled up inside of a syringe, injected, and then unfurled
- No bigger than a U.S. quarter.
- Cheaper perhaps(???)
Some issues that I see with this are:
- The material in which we could coat the implant in (The age old question) that would be able to be thin, flexible, and tough enough.
- The idea of unfurling under the skin. I am pretty sure I have seen this technique in plastic surgery, but I am no surgeon.
- The connections between the coil and the chip inside of the chip eventually breaking due to repeated flexing.
Any insights in terms of advantages and disadvantages? What about materials and how it could be made? Implant procedure?
