Chip in the nail

Support

Hi, today a friend as I use a chip in my hand, asked if I can paste such a chip into her nail. Do you know any t5577 in a very small version? I know there are already such but I am looking for something at 125khz.

Not really buddy, the “problem” is the frequency, and therefore the antenna.

The antenna needs to be long, wide or tall, so you won’t find something finger Nail :nail_care: size that is practical

HF is a different story,

For measuring how dense our heads are?

I believe this is mostly due to the sheer number of turns one needs to balance the resonant frequency. It should be possible to bump the capacitance and lower the turn count and still get performance. With the xEM and other small implants that use a T5577 125khz chip inside we go for very fine wire and the total antenna size is quite miniscule… yet still works well enough with most readers.
