Enlightened by Mo Qingyan, Chen Xin quickly completed the concept of the health wristband.
This thing is not complicated to make. Even before the meteorite fell, there were already mature products on the market; all Chen Xin needed to do was slightly improve them.
At its core, this wristband is merely a sensor patch and a computing chip. The sensor patch detects bodily data like heartbeat and temperature, while the chip processes the detected data to compute and assess your health status.
As for the alarm function, it only requires a preset value in the chip; when the monitored data deviates from this value, the chip will automatically alert without the need for additional operations.
The only issue is the lack of widespread network signals covering every corner like before, so the wristband's alarm function is only effective within the shelter.
