Regular measurement is important to prevent disastrous results. But it is difficult for many people to take a minute to stay with their arm in the cuff.
Recently, researchers in the US were reported to have developed a prototype device to measure the blood pressure readings using a smartphone case. It can record the real-time data, according to the media.

In real, blood pressure is easy to measure. A skilled physician can guess the value immediately after touching the vessel of the patient. But it costs quite high to reproduce such an expert's ability with a sensor.
Blood pressure measuring case will be realized in a couple of years. On the other hand, I expect this sensor will be equipped with a smartwatch. I believe the watch is more suitable than the cellphone because it can always be attached to a wrist. In the future, blood sugar, O2 saturation will be recorded with a smartwatch. This device will be able to send an emergency signal to an ambulance. Such future is approaching fast.
