Google Life Sciences Division Verily develops smart watches that measure heart rate
Release date: 2016-10-08
According to MIT, Verily, a life sciences laboratory owned by Google's parent company Alphabet, is developing a health smart watch and has produced hundreds of watch prototypes. Antonio Regalado said that the current white round watch shape (at least two upgrades), compared to the first generation of the square shape in 2015, the change is quite large, as for the future final product, what is the chief technology Official Brian Otis did not disclose accurate information.
A year ago, the first time I learned about Alphabet's smart watch, the square shape, designed for research and clinical use, can measure heart rate, skin temperature, low-dose illumination, noise level, etc. At that time, it was a very forward-looking look at Google X Lab. s project. Although Google has undergone a major restructuring within a year, the pace of innovation has not slowed down.
Unlike the Apple Watch, the Verily watch is not a consumer device, but is positioned for medical research to monitor a person's physical condition on a large scale, most likely for a large health Baseline project.
The Baseline project is a collaboration between Verily and Duke University and Stanford University to create a big data disease prevention diagnostic technology by collecting biological samples, depicting a biologically significant biological data, and identifying biomarkers for each disease. Even prevention of epidemics or common diseases such as heart disease and cancer. Later this year, Verily may test 1,000 to 2,000 people.
There are some special differences about the specific technical details of the watch. Traditional smart watches use LCD or OLED displays to display rich colors, and this watch is equipped with an electronic ink display, which not only helps the wearer achieve longer battery life, but also from another The side proves that the device is not for consumers, and more uses to collect health data.
What data is collected? Brian Otis calls it "a heart and activity monitor." On the sensor, there is nothing new on the hand. It is used to detect motion accelerometers and gyroscopes. There is also a pulse volume wave on the back. LED lights to measure heart rate, as well as other sensors that can be used to detect skin electrical responses, will also incorporate blood pressure measurement features in the future, which are not common on Apple Watch and Fibit fitness bracelets. It is foreseeable that the new watch will play a big role in preventive care and remote monitoring.
Verily has made some efforts to improve the accuracy of data collection. The first is to test the data of different positions of the body through the ring of peripherals, and use the metal pad on the back of the watch to complete more accurate ECG measurement. As for the accuracy of the data, The engineer did not give an exact number. In addition, in the measurement of blood pressure, Verily is also looking for a new breakthrough method. At present, David He, a blood pressure measurement expert of the famous startup Quanttus, has been dug up, and the road to innovation is arrogant.
According to Brian Otis, chief technology officer of Verily, the company is still developing its own chips, trying to minimize energy consumption. With sensors for various data in the human body, the index of the user's body can be monitored at any time. From this perspective, Apple's Apple Watch can't do this. Perhaps this watch is just a small part of Verily's big health project, and the company is working hard to support better clinical research services through smart hardware and big data analytics. This is Verily's great ambition.
