Yes, through electric current stimulation, to achieve the reminder effect

At present, it is still a concept product, and the structure has been evaluated.

This is very easy to realize. Before that, children bowed their heads and issued an alarm to correct their sitting posture.

Yes, so I went to the structure to get it.

Speaking of the correction belt for correcting sitting posture, I bought a Mi posture belt with millet products before. It cost nearly 200 yuan, which was a complete waste of money. Sometimes it was too sensitive and sometimes it didn't respond after passing a threshold and an angle. Moreover, there was a problem with the design. It was very uncomfortable to wear, not to mention writing. It was uncomfortable to wear and play with computers. Even if I was sitting well, the underarm belt was strapped, I don't quite understand that I have to do homework and think about problems when I really suffer for children. I bought it for a while and then ate ashes. I really can't buy health care smart products casually

I 've tried it too. It's very tight. It's hard for a long time.
