This teardown reveals the capacitive senor design in Mi Band 3.
I did an experiment to demo what I have always emphasized, the input signal appears more on the smaller plate than on the bigger plate.
The Mi Band design showcase an innovative way of implementing swipes on display, without using ITO, an expensive material.
Last but not least, the battery life of Mi Band is impressive, 3 weeks on one single charge, thanks to the capacitive sensor used.
In case you are just as impressed as me and want to find out more about the sensor IC, here is the link:
