Can Taobao's smart watch measure blood pressure? Is it true?/You don't say.

Can Taobao's smart watch measure blood pressure? It's fake. Some smart watches sold on Taobao claim to be able to measure blood pressure, but the authenticity of these claims cannot be confirmed. At present, some smart watches on the market do have the function of measuring blood pressure, and they are usually equipped with heart rate sensors and other related sensing technologies to estimate blood pressure. The measurement results of these non-medical devices may not be as accurate and reliable as professional medical devices. So some smart watches claim to be able to measure blood pressure, but the accuracy may be different.
