The device measures blood pressure through several sensors which simultaneously measure the contact pressure, pulse and blood flow on the surface of the skin in the vicinity of the wrist.
Yes, Sir Isaac Newton is best known for his work on gravity. He also worked on and discovered many other scientific wonders during his lifetime (1642-1727).
What Else Did Sir Isaac Newton Discover? Besides his work on universal gravitation (gravity), Newton developed the three laws of motion which form the basic principles of modern physics. His discovery of calculus led the way to more powerful methods of solving mathematical problems. His work in optics included the study of white light and the discovery of the color spectrum.
